Helped Jay3 out with making a b35 harness for his car this past weekend. He ended up having a 25 pin harness so we did the pinout.
pin 1: Blue/White Oil Level Static
pin 2: Blue/Yellow Oil Level Dynamic
*pin 3: Red/White 12v ABS Power
pin 4: Not Used
*pin 5: Black/Grey Pressure Switch Compressor Relay
*pin 6: Black/Blue Auxiliary Fan (ECU Aux Fan On Alert)
*pin 7: Black/Violet Driveaway Protection from OBC
pin 8: Gray Check Engine Light
*pin 9: Green/Blue Not Used
*pin 10: Brown/Black Transmission Park/Neutral (Lets the ECU know when you're in Park/Neutral)
*pin 11: Brown/Yellow Ground For Temp Sender Gauge
pin 12: Brown/Violet Coolant Temp Sender Gauge
pin 13: Green/Violet Fuel Pump Relay
*pin 14: Black/White Vehicle Speed Signal
pin 15: Black
pin 16: Tan/White
pin 17: White/Violet
pin 18: Black/Yellow Starter Terminal 50
pin 19: White/Green Service Indicator to SI board
pin 20: Black Engine Speed (RPM)
pin 21: Green Ignition
pin 22: Green/White o2 sensor relay
pin 23: Brown/Green Oil Pressure Switch
pin 24: White/Black Present Rate Fuel Output
pin 25: Blue Alternator
That's everything you need and a few more things I tracked down.
EDIT: 4/29 Updated to include all functions. Asterisk'd entries are not necessary for an e28.

I know you'd been busy Brad, so when I had an opportunity to take care of it, I figured I would and spare you the tireless hour going through the ETM.Big Bronze Rim wrote:Good info. Too bad I haven't gotten around to finishing my addition to the FAQ. My trip to Korea and life have gotten in the way.
Now If we can just figure out the damn pinout for the 4hp22eh c238 plug (White) in the glove box next to the ecu to the E34 tranny plug that is black with 8 pins.. 
Im so close but there is a wire or two fu*king me..

Need some help guys. So I was comparing my research of the ETM for a 91 535i to the one Derrith has posted and I could not find Pin 8.
Pin 8 is: Gray Check Engine Light - according to Derrith.
Instead I found Pin 12 twice and on the first occasion it was a gray wire leading to the Check Engline Light. Check picture.
The second time I found Pin 12 it was for the Coolant Temp Sensor, it was brown/violet.
That matches what Derrith posted for pin 12 ; pin 12: Brown/Violet Coolant Temp Sender Gauge.
I also found Pin 11 spliced(?) with Pin 12, and that went to the other side of the temperature sensor. According to Derrith it is the ground for the Coolant Temp and seems to make sense. Check picture.

Late 90 I think after september into 91 use the 25pin. I think that's what the ETM said.demetk wrote:Are you referring to the diagnostic link? I see a 20 pin connector in the ETM for the 91. What model uses a 25 pin connector?The Don wrote:Still looking for input. Was it a mistake on whoever copied the ETM?
Weird. The 91 e34 ETM shows a 20 pin layout:The Don wrote:Late 90 I think after september into 91 use the 25pin.
