Ok, this one is gonna get into the weeds.
I am still working on my m42 2002 swap. I am now into wiring stuff.
Years ago when I was doing some m20 swapping I did a pretty comprehensive c101 pinout thread. I did it year by year and used all the etks I could find. Unfortunately the etks online are incomplete, but I did the best I could.
Today I was working on my m42 harness and decided that I wanted to get rid of the diagnostic connector so I didn't have to mount it in the 2002. No need for it.
I went through the etks for a 91 318is and an 89 325i to get a meshed view of what the pinout was. Got it all figured out and found that there was nothing keeping me from removing it. So I proceeded.
That's when I found something strange. A green and yellow wire leading from pin 6 on the c101 to pin 16 on the diagnostic connector.
The wire is in the etk for an '89 as grn/wt and it is supposed to splice and go to the oxygen sensor heater relay. Pin 6 on the c101 is shown as getting power from fuse 9 and is one of the wires that I was going to power on my build. Now it would seem that is not necessary.
Does anyone have a full etk for a '91 318i?
