On several of the diagrams the wire color changed from one side of the plug to the other ( dash harness vs. ECM harness.) In this case I used the DASH harness color ( some ECM harness side wire colors specified in ( ) ). I did not take the time to pull out each of the dash harnesses - so It's possible that I missed a wire or 2. If anyone spots a problem just let me know and I'll edit.



Hope this helps !
