Early Motronic Engine Harness

Post by CASixer » Wed May 20, 2020 4:58 pm

Seeking an engine wiring harness for a us-spec, 1982 early Motronic car.

Anybody got anything that could work? I'm in CA.

What motronic version are you looking for? 1.0?

I found a harness and only then did I discovet my problem to be a stripped ground bolt.

All fixed.

Glad you got it sorted. I've said it dozens of times to dozens of BMW owners, BMW are very, very ground-critical. One bad ground of all the ground connections can cause all sorts of weird problems, not the least of which is a no-start.
