E34 Forum Members (newbie or OG):
Please read over the FAQ... all of it.
I have tried to organize it into more manageable sections with the most frequent questions and helpful answers.
It should take no more than a couple of minutes to scroll thru and find an answer, and no more than 5 minutes per section to read it.
Some answers are a bit tongue in cheek... but will give you a taste of what to expect in the forum itself.
Tips for newbies: Click on links that say 'search' and it will take you to a search with the best keywords for that question.
This is provided just in case you don't know the technical terms or common terminology used by the forum, and should help you get more valid and up-to-date results than a single link.
As always much thanks to Binjammin for lighting a fire under my butt to create this.
Thanks also to the rest of the e34 group, without whom this FAQ would not be possible.
Thanks guys for almost two years of great assistance and e34 knowledge sharing as our own subforum!!!

forum member Jan K /5mall5nail5 has built his own kit using radial mount wilwood 6pistons and larger diameter OEM BMW rotors,
you can buy the mounts from him and source the other parts yourself from your choice of discounters. Check for details at newsweden.com
2: what are some recommended pads?
Hawk HPS, HP+, Raybestos QS and others... best is to search and/or research for yourself. Everyone is looking for some compromise between quiet, rotor friendly, dustiness, cold performance, and maximum braking power.

Major updates to the E34 along the model cycle:
1989: 525i/535i debut in North America
1991: M50 debuts in 525i, replacing M20
1992: 525iT debuts in North America
1993: M50TU debuts in 525i, replacing M50
mid-1993: 530i/540i replace 535i. M60 engine replaces M30. 530iT debuts.
1994: Prewiring for autodim mirror/rear maplights changes to PnP harness. Search for more info.
1995: 525i gets wide grill from 530/540.
Changes are MTech sideskirts, body colored lowers, gathered leather door panels, repeaters, &
power telescoping steering column (late build), EWSII (1/95+), and a colored roundel on steering wheel.
525i Value Edition (stripper model) is available.
525i Olympic Edition also available: featured rear headrests and green piping on the seats...
Wheels:
1: Will the wheels from _____ model BMW fit?
A: ALL 5 lug BMW wheels that are NOT from one of the 3 series, 3 variants (z3/z4) or SAVs (x5 x3) will fit.
Exceptions: e30 M3 wheels will fit, e39 5series wheels will only fit with a hubcentric ring... see #2.
2: what is hub bore diameter? why do I care?
BMW wheels are hubcentric, not lugcentric. This means the hub is what holds the wheels centered, not the lugs.
As a result, it is very important that the hub bore is the correct diameter, 72.56mm.
E39s are oddballs, they use a 74.1 mm hub hole diameter, which requires the use of hubcentric rings on our cars. It is recommended by members here that you call jim @ the tire rack to order the aluminum rings if the wheels you want are e39 fitment, or you can also order plastic rings from discount tire (A670). As to which is better? <<<SEARCH>>>
3: what is the bolt pattern and offset?
A: bolt pattern is 5x120mm, NORMAL offset is in the ET 20 range... though many larger/wider wheels are et15 which is fine.
4: what are the widest wheels I can run?
A: I don't want to touch that one except generally.. but 8.5 front is almost standard aftermarket fitment and 9.5 rear is also about standard when using "staggered" wheel fitment. Others have wider rims, but for that i recommend <<<search>>> as ET, tire sizing, and ride height and even tire BRAND can become critical factors.
5: what are the largest diameter wheels I can run?
A: 20's have been done, rarely. 19's are a lowered street driven car's limit IMO, and 18's are the most common "large" size. 17's are probably the best handling and riding, and every inch bigger than 17" is an ever bigger trade off between looks and performance/durability.
6: what size tires do I need?
Something with an OD very similar to the stock tire size.
For me that is a 245/40/18 all around.
other frequent choices are 235/40/18 and 255 (or 265)/35/18 in 18.
Others are 245/45/17 or 235/45/17 and 255/40/17 in 17.
there are numerous tire calculators on the web to assist, if you just plug in the OEM tire size.
Suspension:
1: shimmy at 50-60? especially after larger wheels?
Most often thrust arm bushings need replacing. Use 750 or m5 complete arms from reputable manufacturers, lemforder seems to be the best according to board members. It is difficult and false economy to try and replace only the bushings. And yes, the additional weight from larger wheels may cause the problem to become noticeable though it never exibited it on the OEM 15's.
2: What springs/shocks should I choose?
This is absolutely a subjective choice. I suggest <<<SEARCH>>>
And then search some more.
3: How low will ________ get my car?
Vogtland
Drop: 1.8" (45mm) front and 0.8" (20mm) rear
H&R
Drop: 1.3” (33mm) front and 0.75” (19mm) rear
Eibach
Drop: 1.2” (30mm) front and 1” (25mm) rear
Bavauto
Drop: 1.5” (38mm) front and 1” (25mm) rear
Also remember to search.
4: What is SLS/LAD and do I have it?
SLS/LAD is a hydro-neumatic suspension used on the rear of m5s and also 92-93 Touring models (US) Works very similarly to Lowriders, with a hydraulic pump, accumulator, and spring to provide a good ride and maintain height between loaded and unloaded... instead of lifting and lowering.
5: What else can I do to improve my steering/suspension?
Sway Bar Upgrade, Poly bushings, strut tower brace, replace wear items like thrust arms, drag link, pitman arm, tighten steering box, etc.
Lighting:
1: what are smileys/ ellipsoids/ free forms?
Names for the 3 different kind of headlights available on e34s.
US got ellipsoids (projectors) for all but two years
free forms were available those two years, and were far worse (either 91-92 or 92-93).
Smileys is the nick name for E-code projectors, which are the best of the 3.
2: what kind of Taillights can I get for my sedan?
Hella made clear turnsignal lights and smoked lights for your enjoyment.
LOADS of off brand stuff on ebay, as well, if your tastes swing that way.
3: what kind of taillights can i get for my Touring?
None. Seriously. It is DIY paint mods like, red-ed turns or DIY smoked tails or leave em OEM.
The rumours are not true, there were never OEM clears in Europe or South Africa, or OZ, or Japan, or anywhere else.
Hella never made any clears or smoked lenses for Tourings, and there are so few Tourings that the Ebay guys don't make them either. And no, sedan lights don't fit the Touring, outer or inner... sorry!
---"But I have seen pictures!" you say?---
Radicast in Sweden once upon a time, in a galaxy far far away, made clear rear turn signal lenses you could glue in after carefully cutting out the oem amber turns, but those were the only 'aftermarket' lenses ever made for them... They WERE NLA and never came up for sale anywhere.
-UPDATE- Looks like as of today 9/14/08 that radicast is offering them again on their website.
Elekta notes the price in dollars is about $180+ shipping from sweden.
4: Can I add HIDs?
Yes you can... <<<search>>>
5: Brake circuit, Low beam, foglight, or other check control messages
Please take the 30-60 seconds to search the forum for the exact message as it is spelled ... or for it in Clear language.
Stereo:
1: Can I add ______ to my factory radio?
Remember this radio was originally designed in ~1989. If it existed before or by then, probably.
Luckily the CD43, which is newer, is a plug n play option for 91+ e34s. There are many more add on devices for it.
2: Why does my factory radio say CODE?
When power is disconnected, it requires you to enter the antitheft code to reactivate the radio.
3: Can I swap to an aftermarket radio?
YES!!!
4: Can I bypass the factory amp?
94-95 no, sorry. take it to a pro to build all new passive xovers for all 10 speakers
<94 yes but needs an aftermarket radio or an external 4 channel amp
92-93 yes no problem
89-91 maybe... if you are skilled and/or can get moroza to take pics of his amp for reference.
5: What sizes are the speakers? are there any "plug n play" replacements?

2: Why does my car ding when it's 38 degrees?
Simply to warn you that it is cold outside!
At 38 degrees the possibility of ice forming on overpasses and bridges begins, thus the 38 degree ding.
3: Can I jump the car without removing the back seat?
Sure, there is a jump terminal under the hood.
4: How do I unlock my car when the battery is dead?

Fortunately, the E34 does not enjoy the availablity of body kits like the E36 does. this means there are very few to choose from, but also means that we are not barraged with unpainted or tacky kits on every other e34 on the road... thank god. If you live for kitting out cars with fiberglass body mods, the e34 may not be for you.
Bumpers:

1: Will the wheels from _____ model BMW fit?
A: ALL 5 lug BMW wheels that are NOT from one of the 3 series, 3 variants (z3/z4) or SAVs (x5 x3) will fit.
Exceptions: e30 M3 wheels will fit, e39 5series wheels will only fit with a hubcentric ring... see #2.
2: what is hub bore diameter? why do I care?
BMW wheels are hubcentric, not lugcentric. This means the hub is what holds the wheels centered, not the lugs.
As a result, it is very important that the hub bore is the correct diameter, 72.56mm.
E39s are oddballs, they use a 74.1 mm hub hole diameter, which requires the use of hubcentric rings on our cars. It is recommended by members here that you call jim @ the tire rack to order the aluminum rings if the wheels you want are e39 fitment, or you can also order plastic rings from discount tire (A670). As to which is better? <<<SEARCH>>>
3: what is the bolt pattern and offset?
A: bolt pattern is 5x120mm, NORMAL offset is in the ET 20 range... though many larger/wider wheels are et15 which is fine.
4: what are the widest wheels I can run?
A: I don't want to touch that one except generally.. but 8.5 front is almost standard aftermarket fitment and 9.5 rear is also about standard when using "staggered" wheel fitment. Others have wider rims, but for that i recommend <<<search>>> as ET, tire sizing, and ride height and even tire BRAND can become critical factors.
5: what are the largest diameter wheels I can run?
A: 20's have been done, rarely. 19's are a lowered street driven car's limit IMO, and 18's are the most common "large" size. 17's are probably the best handling and riding, and every inch bigger than 17" is an ever bigger trade off between looks and performance/durability.
6: what size tires do I need?
Something with an OD very similar to the stock tire size.
For me that is a 245/40/18 all around.
other frequent choices are 235/40/18 and 255 (or 265)/35/18 in 18.
Others are 245/45/17 or 235/45/17 and 255/40/17 in 17.
there are numerous tire calculators on the web to assist, if you just plug in the OEM tire size.
Suspension:
1: shimmy at 50-60? especially after larger wheels?
Most often thrust arm bushings need replacing. Use 750 or m5 complete arms from reputable manufacturers, lemforder seems to be the best according to board members. It is difficult and false economy to try and replace only the bushings. And yes, the additional weight from larger wheels may cause the problem to become noticeable though it never exibited it on the OEM 15's.
2: What springs/shocks should I choose?
This is absolutely a subjective choice. I suggest <<<SEARCH>>>
And then search some more.
3: How low will ________ get my car?
Vogtland
Drop: 1.8" (45mm) front and 0.8" (20mm) rear
H&R
Drop: 1.3” (33mm) front and 0.75” (19mm) rear
Eibach
Drop: 1.2” (30mm) front and 1” (25mm) rear
Bavauto
Drop: 1.5” (38mm) front and 1” (25mm) rear
Also remember to search.
4: What is SLS/LAD and do I have it?
SLS/LAD is a hydro-neumatic suspension used on the rear of m5s and also 92-93 Touring models (US) Works very similarly to Lowriders, with a hydraulic pump, accumulator, and spring to provide a good ride and maintain height between loaded and unloaded... instead of lifting and lowering.
5: What else can I do to improve my steering/suspension?
Sway Bar Upgrade, Poly bushings, strut tower brace, replace wear items like thrust arms, drag link, pitman arm, tighten steering box, etc.
Lighting:
1: what are smileys/ ellipsoids/ free forms?
Names for the 3 different kind of headlights available on e34s.
US got ellipsoids (projectors) for all but two years
free forms were available those two years, and were far worse (either 91-92 or 92-93).
Smileys is the nick name for E-code projectors, which are the best of the 3.
2: what kind of Taillights can I get for my sedan?
Hella made clear turnsignal lights and smoked lights for your enjoyment.
LOADS of off brand stuff on ebay, as well, if your tastes swing that way.
3: what kind of taillights can i get for my Touring?
None. Seriously. It is DIY paint mods like, red-ed turns or DIY smoked tails or leave em OEM.
The rumours are not true, there were never OEM clears in Europe or South Africa, or OZ, or Japan, or anywhere else.
Hella never made any clears or smoked lenses for Tourings, and there are so few Tourings that the Ebay guys don't make them either. And no, sedan lights don't fit the Touring, outer or inner... sorry!
---"But I have seen pictures!" you say?---
Radicast in Sweden once upon a time, in a galaxy far far away, made clear rear turn signal lenses you could glue in after carefully cutting out the oem amber turns, but those were the only 'aftermarket' lenses ever made for them... They WERE NLA and never came up for sale anywhere.
-UPDATE- Looks like as of today 9/14/08 that radicast is offering them again on their website.
Elekta notes the price in dollars is about $180+ shipping from sweden.

Remember this radio was originally designed in ~1989. If it existed before or by then, probably.
Luckily the CD43, which is newer, is a plug n play option for 91+ e34s. There are many more add on devices for it.
2: Why does my factory radio say CODE?

Alarm Install DIY
OK guys, my alarm came in, though I still have to order the oem connector shell and the pins for that, I can start writing it up for y'all. I'm sitting here at the table wiring and soldering the harness after doing all the needed research, testing, etc.
Goal as always, as near to factory appearance as possible, no hacking or cutting if at all avoidable, reversible without damage.
About the chosen unit:
the RF-420 is a one way AM paging alarm... It is not two way FM... it is not a keyless entry only nor is it a remote start.
EDIT 05/12/10 - the 420 LCD is out of production, the replacement is the 425-LCD and appears to be identical except the remote is nicer.
It has an external starter kill relay, onboard door lock relays (selectable for Positive pulse), onboard parking light flash relay, 3 programmable auxiliary channels and two other outputs, an external shock sensor, an external siren, and an additional input for wiring an additional sensor if you choose (microwave/proximity, tilt, glass break, etc).
In short, it has everything to make all the functions I (and you) want possible, without additional complications or expense.
Functions desired:
Auto Double lock Doorlocks
Flashing parking lights
Fuel pump interrupt instead of starter kill (just like CODE)
Window up and Sunroof close from remote
Pin Protection for all doors, trunk, and hood.
Touring--- remote hatch open, remote glass open
As a bonus it is NOT A DEI PRODUCT (viper, python, rattler, other snake, Hornet, clifford etc)... which means every idiot and his brother don't have a remote that can be added, or know the valet mode sequence. I have sold hundreds of Autopage alarms and they are quality units, with good remote availability later if needed.
Location for alarm will be under the rear seat. Easy access to battery, as well as the Factory alarm 12 pin connector. this location will require extending the wire for the parking lamp flash to the underdash location, as well as the wires for the LED if you want it upfront--- more on that later.
Information sources/ aka Required Reading:
RF-420LCD install and operation manual (available online also)
1992 ETM (available online also)
BMWE34.net Use caution! Some info is IMO very bogus...
http://www.bmwe34.net/Wiki/tiki-inde...=Keyless+entry
This diagram is all you need from there...
12volt.com
http://www.the12volt.com/diodes/diodes.asp
http://www.the12volt.com/relays/page1.asp#n2p
Note- Sedans are much easier... no trunk pop or glass pop needed.
Supplies Needed:
Autopage RF-420LCD - Sourced From Ebay seller dimensionaudio for $75 ($13 shipping- may vary)
Heatshrink of various diameters, from 1/4" all the way to 1/2" or 3/4" ($5-$8 Harborfreight--- optional on larger sizes but i prefer to loom wires via heatshrink)
Package of diodes 1N4001 (up to 1N4007 acceptable) - recommend sundry package of 25 from radioshack -$2.50 PN 276-1653.
BMW parts if wanting to make a connector like the oem alarm (i did not end up doing this):
P/N 61131378138 (1) plastic connector shell for alarm
P/N 61131376202 (15) bare pins for connector... available with wires for more $$$... extras are spares in case you Fubar one.
OPTIONAL FEATURES--- PARTS NEEDED:
Optional 1- automatic double lock-
requires only package of diodes already purchased
Optional 2- window rollup from the remote-
Requires option 1 installed + Fuseholder + 1 additional 'bosch style' relay
(suggest one with socket and flying leads- ie wires)
Optional 3- Hatch and Glass Lid Pop (touring)
Requires 2 additional bosch style relays + Fuse holder
(suggest again with socket and flying leads- ie wires)
If you don;t have the factory alarm (ie never did) you will want the siren bracket, 10mm bolt, and the two wire siren connector.
I do not have the P/N as my car had the Alpine alarm until I ditched it 2 years+ ago.
Tools needed:
Brain
Patience
BRAIN
Ability to solder
Ability to read a rudimentary schematic (this is not a wire by wire & solder by solder pictorial... just isn't possible)
Multimeter (not a test light!)
Small flathead Screwdriver (for de-pinning unused wires from the connector instead of ghetto hacking them.)
Soldering Iron-- preferably both a decent electric + a gas unit for the really thick wires. A $5 electric is ample for all but the biggest connections however.
Solder - I use 60/40 (doesn;t eat the tip, melts and flows easier) on the largest joints as well as 95/5 (eats the tip, but lead free) on the 2 or less wire connections.
Helping hands, or a friend w/ the slip joint pliers from e34 tool box to serve as heat sink when soldering diodes.
NOTE----Diodes are mandatory to join the trunk and hood pins together and to join the FL FR and Rear door pins together for the alarm without F'ing normal vehicle operations-- and the only way to connect them is soldering them in.)
Good wire strippers (think Klein, not autozone/walmart) or a razorblade knife for stripping wires... or both.
A kitchen table, or very large workbench... and something to put down so solder doesn't burn it.
Step 1: Siren
Location: under cowl, right side
Access THRU EBOX, not by removing the cowl grill.
remove Ebox lid, remove tall rubber grommet.
If you have a factory alarm siren (ie code actually makes NOISE when it goes off) you will need to remove the computer to get that older BMW siren out. This is where the 'horn' pin in the battery box actually goes. No reason to run two wires.
Remove OEM mount from bmw siren. Cut siren's wires 1/2way between the unit and conenctor at the OEM solder joints.
This is where the brain comes in. Plan ahead, you need to put the heat shrink for each wire on, as well as three larger id sections to cover everything BEFORE YOU SOLDER THEM TOGETHER
Solder the connection to the new alarm siren keeping them about the same total length, black to black, blue to red, heatshrink each individual joint, then heatshrink the whole thing.
Remove the new siren's supplied mount and transfer the oem mount to it.
Reinstall in the OEM location with 10mm bolt, make sure horn is pointed as down as possible
Reinstall Grommet, computer if removed, and Ebox Lid.
Try code function and revel in the wierd sound.
Step 2: Prepping the harness
Harness preparation --- coming up next... but my hands are tired.
The first thing you want to do is decide which wires you will use... or you can just copy exactly what i did and give the old noggin a rest.
Those you will not be using can easily be de-pinned from the connector
De-pinning them instead of cutting means if you want to go back and add them later, it is as simple as popping the wire back into the connector again... They also don't take up a bunch of room in the bundle or cause confusion (there are multiple whites for example) as you will see when you need 3/4" heat shrink on some of the bundles.
Step 2a: De-Pinning the harness
1: 6 pin Lock harness
Doorlocks are positive pulse "type 3"... and we do not need to intercept the switch signal so we can immediately eliminate two wires from the lock harness. Leave the purples (will be connected to +12 to make lock pulse positive) and the green and light blue, as indicated in the manual for type III locks.
IE eliminate Brown and White from the 6 pin connector, by pressing down on them from underneath with a small flatblade screwdriver.
2: 5 pin harness
eliminate blue/black horn output wire
same method as above
3: 10 pin harness
eliminate violet positive trigger wire
eliminate pink two step unlock
eliminate white dome light output
same method as above
Sedans can eliminate any aux outs they will not use: Tourings need all 3.
Channel 2 grey is trunk pop
Channel 4 black blue will be glass pop (unlock + trunk)
Channel 3 white blue will be used for window roll up (because it used LOCK + trunk... makes more sense)
Step 2b: Looming the harness
By now you are intimidated by the sheer number of wires... you should be.
Guess what, you'll have more.
ON the positive side it will get easier now.
Take each connector and the wires and stretch them out to their full length.
Tie a knot in each end and start twisting the wires in each bundle around themselves.
The OG way is to chuck them in a drill and spin then until they are a tight bundle, if you don;t have a working drill (Like me) You can do it by hand.
This accomplishes two things: makes them easier to manage (each bundle acts like one big wire) and makes them look nice and more factory.
OK you now have several manageable bundles of wires...
Sleeve the Wires for the 10 pin connector for about the first 6 inches with heat shrink, then lay them OVER the top of the unit so they lay alongside the other two large bundles from the 6 pin and 5 pin connector.
The brain box will be on the end of our harness towards the middle of the car and all the connections will be towards the end.
At this point before you shrink them together you can heatshrink any individual wire bundles To make them all 'even' if you choose.
Take a 1" width of heatshrink that will fit over all the wires together and bundle them nicely together, preserving what you have organized.
Step 2c: wiring the harness
Now it is time to start making decisions:
12V power lead
the 12V power supply in the factory alarm connector is inadequate to power a bunch of relays, though adequate to provide the 12V pulse for the door locks (purple wire with fuse holder).
You can leave it that purple wire alone and plug it in at the factory alarm connector 12V, or do as i did and connect it to the red power lead for the brain (which will eventually go direct to battery) to save bulk. I did the later, you can do the former no problem, just make sure you have a fuse in F47 (alarm).
At this point I also soldered in the fuse holders for the aux channel relays to the same 12v lead. I now have 1 single heavier gauge red wire feeding the two extra fuse holders, the 'doorlock' purple wire, and the brain's red 12V power lead. 1 wire= one point of failure.
This is where I had to switch to my gas powered soldering iron as these are a lot of wires and heavy gauge.
Pull the blue and green door lock wires out of the bundled wires, as well as the white parking light flash, ignition yellow, the orange starter kill wire, and the aux channel wires you chose to use. (blue white for window close for example).
RE-loom the rest back together.
Spin the trunk pop and hatch wires together & heat shrink an inch or so
Spin the Orange and yellow together & heat shrink an inch or so.
It is time to split off the white wire for the parking light flash. Fold it back forward towards the brain, and put another 1" ring of heat shrink ontop of the previous 1" ring so it stays pointing that way.
Why didn't we heat shrink the Door lock wires yet??
It is time to install the first pair of our diodes.
Step 2d:Modifying the lock wiring with diodes
Leave yourself 1.5" inches on one lock wire wire and 2.5 inches on the other from the last heatshrink, then cut. go back 1/2" and strip the wire on each.
How to solder diodes to raw wire:
The diodes should point towards the connector...
For those of you who didn't do the required reading, please go catch up. This means the striped end goes toward the OEM connector (bare wires at this point) not towards the alarm brain. Think current flowing downstream... they are a one way check valve for electricity instead of air, vacuum, or water.
On the side without a stripe, bend the lead at the 1/2way point 90 degrees. Leaving yourself a couple of mm of bare wire not touching, wrap the remainder tightly on the BENT portion of the leg. using your pliers and friend method (or helping hands soldering jig) hold the diode between the body and the 90 degree bend. this is for heat protection. Solder the bent leg to the wire and blow it cool. Clip any excess leg off, and bend the leg an additional 90degrees, ie into a u shape pointing back at the diode body. Use your pliers to decrease the radius if needed and you should have the wire and resistor in a nice compact inline package ( i'll see if I can shoot a picture when I do my last ones for the parking light--- look below later).
Complete the other 3 legs the same way, then heat shrink over them to prevent any shorts.
Now you see why we staggered the cuts, the end result should be slightly staggered and reduce bulk in the harness.
Go get the brown wire you de pinned earlier from the 6 pin connector
strip the plain end ~3/8".
ON the LOCK WIRE (green) we will practice a technique we will need shortly, thru wire joining. If you mess up, you can fix it with a normal wire solder/splice here.
With your razor knife, cut just the insulation around the wire an inch or so below the last solder joint/heatshrink. about 1/4-3/8" below that do it again. slice between the two, and remove the insulation.
You should now have a ~1/4" section of bare wire in the middle of an insulated wire.
make a hole thru the middle of the wire using a pencil, small screwdriver, whatever.
Don't make it 3 strands on one and 20 on the other, ok? try to make it somewhat even.
Insert the Stripped end of the brown wire into the hole you just made,with the wire laying AWAY from the brain, and towards the connector.
Twist the stripped 'brown' wire tightly around the exposed green wire, closing the hole up and solder. slide a 1/2" piece of heatshrink over the green & brown to cover the joint.
This brown wire will later become the Ch3 window roll up.
Finishing the lock harness mods:
You need to combine what you have practiced:
soldering a diode, and thru wire joining to wire the diode that will supply power to both LOCK and unlock from the lock wire, and prevent the unlock wire from backfeeding to the lock.
I suggest two inches or so, and the first thing to do is slide a 1" piece of heat shrink up the lock wire.
At the 2" mark for example, make your circle around the wire with your razor knife, then 1/2" below that another and remove the insulation.
Bend your diode leg 90 degrees ( stripe pointing to connector, so black side leg!) and stick it thru the wire.
Leaving yourself a few MM, spin the rest around the leg, solder, trim leg, complete bend.
DO not heat shrink it yet. Just make sure you have your heatshrink above it, this is your last chance.
Bend your other leg 90 degrees, and hold it up against the blue unlock wire. a few MM above where the leg sits, make your first cut, and about 3/8" down make your second cut and remove the insulation. Solder the other end of the diode in place as above.
Slide the heat shrink down from above and cover as much of the diode as possible, then slide a piece from below.
Finally slide a piece over BOTH wires and heat shrink it...
Congrats... You have now wired the locks to auto double lock:
current on the lock wire flows thru both.
current on the unlock stays on the unlock.
current from Channel 3 relay via the 'brown' wire will be applied to both (rolling windows and sunroof closed when applied for longer time) without back feeding to the alarm.
I'll try to make a diagram at some point, or one of y'all with more graphics time, photoshop etc can do so for me.
Tidy everything up, take it out to the car and check for length, or at least trim up the bundled harness so everything is the same length as the shortest wire... relays are next.
Some pictures: Still one relay to install (bonus points if you can figure out which one it is )
I'll cover the details of that later.
Many updates above:
Diodes continued:
Go steal the blue/black wire you depinned earlier.
We are going to use this to turn our single Hood/trunk wire into two wires.
At a convenient place, clip the blue wire. strip each end ~1/2.
Slide your heatshrink on it.
Strip the end of the blue/black wire.
Now take Two diodes, and bend the legs 90 degrees as discussed earlier (black side). Twist the legs together. then twist the BRAIN side of the blue wire around it and solder it. clip the leg, bend em flat and heat shrink them.
Now take the remainder of the blue and the blue/black and solder one to each remaining leg, and heat shrink them. You now have individual trunk and hood leads.
Step 3: Adding External relays
ok First the 'starter interrupt relay' <included with alarm> which we will be using for a fuel cutoff instead.
wire colors are yellow and purple (twist these two together), red, and white.
The yellow wire from the brain, ignition, will be tapped to the red lead from this relay. use the thru wire technique to connect them.
The orange lead from the brain, starter interrupt, goes to the white wire, clip them off and twist them together.
the relay's yellow and purple will be later be spliced into the factory fuel pump wire, which is near the 12 pin alarm connector.
Aux channel relays
The relay for channel 3 should be connected to power (fuse holder) on terminal 30 and 85, white/blue is connected to 86, and the new brown wire you added earlier goes to 87 (not 87a).
For channels 2 and 4 (touring): power on terminal 30 and 85 together from a fuse holder. The color of 86 will be (#4) black/blue or (#2) gray.
You will add your own wire on each relay's 87 that will go back to the hatch harness relay area to be tapped in and throw the original relay.
btw guys: I temporarily plugged it in, double locks work great. I need to go find my space heater and extension cord and wire up the hatch pops temporarily just to see how it all works together.
Tourings:
Remove the right side cargo trim cover, and pull the relays (very small black ones, end of the row).
Colors and function:
white/blue or white/black stripe is signal from switch, brown is signal ground, red/whites are constant power, red/black is hatch pop out, and red/blue is glass pop out.
Note the patterns, blue stripe for glass & black stripe for hatch.
you can go on the other side of the relay (since you have a relay already) or you can just trip the relay with the ones you have... your choice.
Either choose red/____ or white/_____. I'll be tripping relays.
The brain sits between the battery and tunnel and the harness basically wraps around the battery to the connector.
Still need to order the connectors and buy another relay, some 'red/black' zip wire to extend the LED to the rearview mirror (using the integrated one in my e46 mirror), and a spool of white wire to extend the parking light wire to the switch this week so I can finish it up.
OK, I added my last relay to the harness (window rollup relay), and need to finish this up, as school resumes tomorrow.
the kids are finally in bed and I need to go finish running the wire for the mirror led, and the parking lamp flash that I started at 10 hours ago.
which means I need to go take pictures of the diode soldering like I promised earlier.
I'm not going to wait anymore and order the connector, it is getting hardwired tomorrow afternoon, and I'll leave a pig tail on the existing connector in case I want to put it back.
update: I got the wire for the mirror LED in and ran the wire for the parking light flash up to the front.
Too dark nad too cold to continue further. It will be in tomorrow after classes though.
ok it is in.
it'll roll up the windows and close the sunroof.
However while the alarm is busy doing the timed 'lock' signal, you can't reopen the car. I left it at 20 seconds for that reason. Easy enough to hit it again if the double sunroof AND all windows were open, rather than being locked out for 30 seconds - 1 minute.

The complete guide to E34 front struts and mounts
BMW had 3 different strut mounts in E34's. They are all interchangable between cars but struts have to match. I.E. you can take a strut and matching mount from any E34 and install it in any other E34. Rears are all the same. (EXCEPT SELF LEVELING - not covered here) Click on the diagrams below for all part numbers in the diagram
The best way to tell what you have is:
Check the cap and top strut nut.
If 1 1/8 inch (small) you have Version 3
If 2.5 inch and a 19 mm M12 nut then you have Version 1
If 2.5 inch and 22 mm M14 nut then you have Version 2
Version 1:
525i, 535i, M5 3.6 (88 - 07/90)
Dustcap - 2.5 inches

Here is a great overview explaining EWS

Also here is picture for EWS Bypass.
HERE IS SOME MORE INFORMATION REGARDING THE BUMPER/LIP POST THAT ZUBBIE MADE REGARDING THE VOLVO FRONT BUMPER LIP:
The volvo lip can be found on the following models:
88-90 760
90-92 740
91-95 940
92-94 960
All sedans, wagons, turbos and non turbos will have the same lip in those model years. All other model years and 240s have a completely different type of airdam.
STRAIGHT FROM R3V. TIM POSTED THIS INFO IN A THREAD A WHILE AGO.
OBC IV Manual redrawn and updated to be a fully-searchable PDF.
Redone so that each page fits on a half-sheet of 8.5 x 11 paper; if you set your Acrobat Reader print settings properly, you'll be able to print it out, fold it in half, and toss it in your glove box.

Other Important Information (thanks to de Witt for this info):
THE E34 M5 EXTERIOR PAINT LIST:
Author's Note: "Perlcolor" is similar to the metallic finish, but is German for "Pearl Color."
This applies to the finish of the paint, which has mica flakes added to create the "pearl" effect.
Avus Blue or Macau Blue M5s' are the best example of the pearl finish in my opinion.
All metallics contain a metallic finish component, paint code 98.

Color Notes and Details:
-Alpine White "Alpineweiß" (218-300):
Interestingly enough, there are in total five different shades of Alpine White, but only three made it to the M5, Alpineweiß II and III.
7 M5 Tourings came in Alpine White II, and only 2 M5 Tourings came in Alpine White III.
- Arctic Silver Metallic "Arktissilber Metallic" (309)
- Avus Blue was introduced to the M5 in 9/1992:
Note: The sticker in the engine bay will state "Avusblau-Metallic," but BMW offically recorded this color as "Avusblau Perlcorlor."
I have a BMW Service Bulletin from 1997 that states "Avusblau Perlcolor" to be the correct name.
However, Avus blue is regarded as "Avusblue-Metallic" in the BMW community. If you want a PDF of the Service Bulletin mentioned above.
- Brilliant Red "Brilliantrot" (308)
- Brokat Red Perlcolor "Brokat Rot Perlcolor" (259)
- Calypso Red Perlcolor "Calypsorot Perlcolor" (252):
Even though it is a stock color, BMW used it for the 1995 Special Edition M5. Introduced to the M5 in 9/1992.
- Cosmos Black Perlcolor "Cosmosschwarz Perlcolor" (303)
- Daytona Violet Perlcolor "Daytonaviolett Perlcolor" (283):
The most common color for M5 Tourings, at 206 Tourings.
- Diamond-black Metallic "Diamantschwarz Metallic" (181):
Diamond Black-Metallic came in two different shades, Diamantschwarz Metallic I and Diamantschwarz Metallic II.
- Fjord Grey Metallic "Fjordgrau Metallic" (310):
14 M5 Tourings made in this color.
- Granite Silver Metallic "Granitsilber Metallic" (237):
- Jet Black "Glanschwarz" (668):
This paint was only available for the E34 M5.
- Lagoon Green Metallic "Lagunegrün Metallic" (266):
Introduced to the M5 in 9/1992.
- Macau Blue Metallic "Macaoblau Metallic" (250)
- Mauritius Blue Perlcolor "Mauritiusblau Perlcolor" (287):
One of the original E34 M5 colors. There were only four US-spec E34 M5s produced with Mauritiusblau.
Note: The sticker in the engine bay will state "Mauritiusblau-Metallik," but BMW offically recorded this color as "Mauritiusblau Perlcorlor."
I have a BMW Service Bulletin from 1997 that states "Mauritiusblau Perlcolor" to be the correct name.
If you want the Service Bulletin mentioned above in PDF format.
- Mugello Red "Mugellorot" (274):
Introduced to the M5 in 9/1992
- Oxford Green Metallic "Oxford Grün Metallic"(430)
- Petrol Mica Perlcolor "Petrol Mica Perlcolor" (305)
- Polaris Silver/Imola Silver "Polarissilber, Imolasilber" (60):
Polaris Silver/Imola Silver supposedly came in different shades (559-563-576?), but it is not confirmed as of yet.
- Rosso Red "Rossorot 95 3567 BASF Fueller ROT:
BMW individual GE00325, used on the LTD M5s in the UK. This is the same code as Romantikrot (369).
- Sebring Gray Metallic "Sebringgrau Metallic" (229):
This paint is exclusive to the E34 M5.
- Sterling Silver Metallic "Sterlingsilber Metallic" (244)
- Techno Violet Perlcolor "Technoviolett Perlcolor" (299)
- Wine Red "Weinrot" (224)
Sonderlackierung
These are the paints produced by BMW Individual. If the reference label on the passenger shock tower says "490" then it was painted in a BMW Individual Color.
M5s manufactured after 10/94 carry a label that says "BMW Individual" on the shock tower and a more specific color description or paint code number.
92 of the M5 Tourings were ordered with "Sonderlackierung" colors.
- Amethyst Metallic "Amethyst Metallic" (452)
- Aqua Metallic "Aqua Metallic" (451)
- Estoril Blue Metallic "Estorilblau Metallic" (335):
A very common E36 M3 color, but was first used on the E34 M5. Surprised?
- Orinoco Green "Orinicogrün" (FQ 95-3450) (406):
Orinoco Green is a BMW Individual color. It was used by BMW in 1995 for the Special Edition M5.
- Night Blue Metallic "Nachtblau Metallic" (453)
- Santorin Blue "Santorinblau" (318):
BMW Individual special order color. Only known to be used on M5 Tourings. Similar to Audi's Nogaro Blue, as seen on the S4.

Interior Colors (please PM me if you know of other options - this is not an exhaustive list):
Cloth and Vinyl options:
Blue, gray, black
Leather:
Tan, Parchment, Black, Blue, Gray, Dove Gray, White?.
Two-tone dark gray on black, two-tone dark gray dove gray (10th Anniversary Japan models only)
I have seen one Individual model that had black bison seating with special charcoal cloth inserts with gray and purple accents. This was on a Canadian Individual model 530 - I can't find the VIN at the moment, but I'll update later.
Leather options were cowhide and bison.
Alcantara:
Many options of alcantara were available, including some unique M patterned cloth inserts.
Numerous BMW Individual choices are known to exist:
- tobacco
- purple
- madiera
Cars were available with 'normal' leather (leather seating surfaces), 'extended' leather (add leather center console), and 'komplette' leather (add leather dash as well).
There are photographs of at least one car produced through the BMW Individual program as having a leather headliner, as well as others with alcantara headliners and rear parcel shelfs.
I'm sure this link is posted on the forum somewhere, but it has a lot of googling compressed into one site and I've found it pretty useful:
