I am helping my neighbor who was working on changing out his flywheel and the transmission dropped which caused the system control wiring to separate at the connector from the transmission. I have researched and all I can find is a different color code for this connector. I will list the colors that I am looking at and hope someone can help me........ help my buddy.
1.red
2.yellow/black
3.red/black
4.violet
5.blue
6.tan/black
7.green/white
8.pink
9.black/green
10.green
11.pink/black
12.pink/black
