Put a new harness in my 94 a couple of years ago because of all the mods and stuff others had done before I got the truck. I found out that the neccessary connections for anything power had to have more connections on the harness and mine did not. If you are lucky you might find one at a pull n pay if you are there before anyone can start to tear into it, and get the correct harness. May take awhile, but gives you another excuse to visit and see whats available. The complete harness I got cost less than $20.00 for the whole interior of the cab.....
