I am swapping out my M42 out of my 91' 318i to an M20b25. I have the wiring harness to the M20 still connected to the motor, i just disconnected the chassis plug and the computer. I did the same thing to my M42 when i pulled it.
Chassis plugs are the same but the prongs are in different places. I need to know what each prong is for on each harness so i can rearrange the prongs on the M20 harness.
They are labels 1-20. Not all of them are used. The M42 uses more prongs then the M20. My service manual doesn't tell me anything i need to know.
Any help is appreciated. Thank you.
