1997 318ti Engine Cable Pin Out Looking for the X69 and X6031 pinouts, I have below what I've come up with so far. Working on an engine swap, and found some write-ups here and there, most did not apply to my vehicle but some did. Used wiring Diagrams to get the information I currently have. I will put below everything I have so far down below.

You need the model year specific ETMs which I can provide. There were subtle changes each year so there is no “one” answer to the question. |
My year is 1997. I spent some time tracing each wire, unfortunately had to cut most of the insulation off, but I did come up with a designation for each pin. It will be attached in a google docs link. Wouldn't hurt to have another set of eyes look over it and make sure I'm not making a silly mistake. I hope this helps anybody that may be in the same boat as me trying to find x6031 and x69 https://docs.google.com/document/d/1...vJdWDhZ0/edit? |
