I've never used the truck parts but when I approached my build it seemed to me the computer and all the other parts don't know the difference if it's in a 1962 or a 2002 car. Any tuner can adjust the speedo and eliminate the anti theift stuff for you and the rest of the system couldn't care less. So I didn't see any value in buying a new aftermarket harness for it when I had the factory one with the engine it belongs to and I know they work together.

I found it very helpful to have factory shop manuals for my donor. About 80% of the book is useless but that other 20% is priceless. I just used the diagrams in the book to hook up the power, ground and the other 20 wires from the car to the harness and it worked fine. But again I did a 2002 Camaro into a 1996 Miata so I could be totally out to lunch with the system you have and what you are doing.
