AX15 TO AW4 Swap

[tjbuggie]

Hey guys I am looking at doing a swap from an ax15 to an aw4, and have a few questions. My main question is the wiring, I have a 1988 that the trans is going in and a 1988 that the aw4 is coming out of, so do I need to take the entire harness out of the donor and put it in the truck I am building? Other than the major components...trans, pedal assembly, shifter, TCU, what else do I need to pull out of the donor?

 

Thanks for any help you can offer
