I have a car that I reluctantly purchased from a friend to help him out. Thought it would be easy enough to get it on the road to give to my nephew. It was in a fender bender and the TCM module wiring got damaged. I fixed that but still cant get the TCM to talk to the car. I may need help from a wiring specialist or at least a good wiring diagram. The one in the Haynes book is incomplete. Any sources for a good diagram I mostly need to find out where the blue/black wire gets power. Thanks.
