you will need the wiring diagrapm for both switches and needs to be re wired for the aod switch. not easy if you have never done it before. a shop with the expierence would be my suggestion.

I have been told that all i have to do is put the truck in reverse with the key on and the e-brake set. take a test light and find out which terminals are hot. on the harness that i have a jumper wire in so that the truck will crank with the key in park or neutral. i have one terminal that is hot and on the other terminal i have 2 terminals that are hot. all i should have to do is test them until the lights come on right? that's way to much hassle to rewire the entire wiring harness especially on this old of a truck
