You can see my other thread on my injector/misfire issue, but am ultimately trying to resolve an issue with misfire/running on 3 cylinders post engine swap in my '91 325i. As part of that, per recommendation I have swapped to a different engine wiring harness (from a 1990). Unfortunately, this has lead to a host of new problems and I am about to push the car into a lake
I swapped out the main harness, went to crank the car, and get nothing. Dash lights, etc, all fine, but no cranking. Swap relays from old harness to "new", still nothing. Check fuses, all seems fine. Battery is brand new and was firing up literally hours before. Start diagnostics and I find that I am missing pin 20 in the C101 connector.
Doing some digging, I find that some later harnesses apparently came this way?
SO, do I need to hack into the harness side of the C101 and run a pin from there back to the dme connector (which I also don`t want to really hack into)? Suggestions on this one? E30 Zone wiki has some slightly confusing verbiage on this, so looking for anybody that has encountered this and how they resolved it!
This does not resolve my current no crank situation, but I have more diagnostics to do in tracking that one down....Either way, want to resolve this piece
