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
