Well here it is... a e39 wiring thread!
I've gotten to that point on my project and found a huge lack of information. Seems no one made any notes, and the websites that had good info have removed it recently. I borrowed Brandon's Bentley manual, which has an entire different book for wiring and electrical and is 838 pages of diagrams.
I will post my useful findings as I go and hope you guys will have some input also.
Seems most people ditch the DME and use a relay to ground out the DME relay. Any more info on that? Which relay is the DME relay, what wire gets grounded?
Any issues with the EWS system?
Any wire color and location info like tach, temp gauge, starter wire, ect...
Will grounding the DME relay make the fuel pump relay function correctly without any modification?
Links to websites with info

I thought I sent you a PM with the DME pinout info, maybe it was nsobiga. If he still has it, 90%+ of what you need is there. The DME relay will send power to the fuel pump relay when it's fed a ground. You will need to ground the fuel pump relay to turn it on. I used 2 extra relays to convert polarity to send + to these relays to turn them on. You could re-wire the relays, and I think someone else came up with another clever way that didn't involve 2 extra relays, but I guess I was feeling lazy.

Must have been him as I haven't seen that. Would love to have that info posted up here!
I believe I emailed you an Excel file with pertinent cluster and DME pinouts. Surely it must have answered some of your questions.

The chassis must always be regarded as a means to an end and never as an end itself
I plan on posting that up when I get to work tomorrow.
If everyone could throw all of their pics and knowledge in this thread it would make a great sticky and an awesome source of info. This would help a lot of people out on one of the most intimidating aspects of swapping an ls engine into an e39 chassis.
Edit: and keep your pm's down

I will wire someone's car if they come and hook up my AC (hoses and all). This is an open offer!
Oh, and I'll also throw in cluster programming / warning light removal service, including working MPG gauge, OBC, etc

^^ That is tempting. I do have all my AC lines left over from my car. Would need to braze on the GM fittings, though….
Great idea for this thread. It’ll be nice to have one “go-to” place to have wiring questions answered.
Since I am brain-dead with wiring and have a terrible memory, I’ve tried to save every snippet of wiring information I’ve ever come across since I started doing research on this swap back in June 2012.
While it was freezing outside in December I started to tear into my untouched 2003 Chevy Express Van harness to take out the unnecessary circuits. I had the following questions:
James was nice enough to send over a detailed post on what needs to be modified on the GM harness.

Some were not in my specific PCM connectors (since the van was not 4WD among other options), so those are labeled "NOT PRESENT".

That is pretty much everything I have that pertains to modifying the stock GM harness out of the car.

I have a habit of saving very useful links and emailing them to myself, so I went back and looked all this info up from the past 6 months.
Here’s what I have as far as mating the GM harness with the BMW harness and actually doing the “swap” wiring.

Well played, sir.
A helpful pic:
I don't have my DME or DME relay anymore. I ran my fuel pump trigger wire directly to the file pump.... So I guess I'm not using my fuel pump relay either, didn't like the idea of relays to switch relays, that's just me.
I used a pre made harness from GMPP comes with the ECU, throttle pedal O2s and a harness. Let me tell you it makes wiring a BREEZE, no de-pinning and rewiring harnesses. The way I did mine I had to tapped power into pin 7 of X6011 which is a white 11 pin plug in the ebox that turns on the abs module and gets the speedo working.
Pin 10 (black) for CEL and pin 6 (black) for tach, I don't have water temp hooked up because the gauge in the cluster is useless, that's for the KOM cluster not the IKE cluster.
I have no EWS in my car either, when you remove the stock DME the EWS is disabled I believe.
Coding, I changed the following: Can-drehzahl (rpm)Konventionell
Can-ganganzeige (gear display)
Konventionell
Can-kuehlmitteltemp (coolant temp)
Konventionell
Motor-faktor (4cyl or 6cyl tach)
2_imp/umdrehung (for 4cyl tach)
and I'm sure there's more, just can't think of it right now.

You got the E67 ECU kit right? That's the one I got too if so.
More please.

Guys using the stock temp gauge, are you putting the e39 sensor in the LS?

Interesting. I'll be honest, i dont care about it being accurate as I use a scan gauge in the car to monitor everything. I just cant stand having something like that in the dash not look like its working. I have the e36 sender in the head now, so maybe that will provide a close ohm range.
You guys just love to make things complicated, even the second time around

Someone had previously removed the DME relay from my car. Seems to me the relay triggers power to two fuses in this little fuse block and the large red/white wire going into this 12 pin connector:
Any reason not to use a seperate relay to power those rather than make a ground for the DME relay?
That's the wire that powers the abs module, which you need for the speedo to work. It needs power somehow, I rigged up my own relay instead of using the stock relay.
I have been spending time reading wiring diagrams and putting together my plan. I'm curious if there is a place to find connector locations. Obviously diagrams give me a connector number like X60xxx, but trying to find these connectors is a bit of a pain.
That's what I liked about the online WDS (before they took it down) it gave you pictures of the connectors. I might have a cd with WDS on it, I'll look for it this evening and see what all it has on it.
You people are starting to scare me
WDS is still available online.
