Looking for old (1988-1990) E34 Instrument Cluster Pinout

[ck3k]

Hear hear!

I'm looking for an old, obscure E34 Instrument Cluster (speedometer) Pinout to create a test bench via power supply.
This Instrument Cluster is from year 1988-1990 (probably 1990), couldn't identify Manual EURO Model.

I can't find pinout description for this particular model anywhere. I checked Wiring Diagrams from armchair, but they all show new pinouts that looks totally different. I know there are various pinout for different clusters (low/high), but this exact old model is really hard to identify.

I've tried looking EVERYWHERE, and here on forums:

http://www.pet-racing.de/E34
http://www.exx.se/maintenance/instru...34/index.shtml
https://www.armchair.mb.ca/~dave/BMW/e34/

None of these shows the pinout for the model I have.

Hopefully someone from bimmerforums can help me

The pin-outs are available in the Bentley book.

The pin-outs are available in the Bentley book.

probably not in the Bentley or the US wiring diagrams, this cluster was only used on EURO spec. E34 520 M20B20, and that cluster was only used 1988-1990. That is the low version and still has the plastic gear parts inside. It was also never used on E32. BMW 9220300798E , BMW 8351581 / MotoMeter 7020001003 , BMW 1384287 / MotoMeter 7030001002, : 240KMH, 9 2203 007 98 E, 8351581, 1384287, 7020001003, 7030001002

check these pinouts from the German E34 forum https://www.e34.de/tips_tricks/bctips/bctips.htm
part 1 shows the low cluster
up to 1990 and from 1990
part 2 shows the high versions

@shogun is right, Bentley either shows US wiring diagrams or it displays post '90ies schematics. Thanks a lot for the links mate. Spend whole night debugging it on ring0 Ah well, at least I managed to do it

Here is for a future reference
