m104 3.0 to 3.2 swap harness question
I have figured that the new engine I have is the older version 104.992 and was wondering what engine harness I need. (did not receive wiring or ecu with the new engine) I was told I needed the A 124 440 5232 but I have found harness with a part number A 124 440 5632. My question is: will it work or not? And what about ecu ?
