Find someone with the same model truck as yours, and trade strait up, thats what I am doing in about 2 weeks, if all goes well. Costs nothing if all goes well. Costs will depend on how much you break during the swap. Just have the trucks sitting side by side, and do the swapping. I have a 95 model truck, so the wiring is probablt different, I have alot of info on that too, be glad to share it with you.
Later,
Willie
