i have a friend with a 79 PowerWagon that is just for parts now so i thought i could take some of the wiring under the dash and some of the engine compartment. Doses anyone know if this will work or not, the main connector on the firewall are the same, but i dont wont to put something in that just doesnt work together with what i have. i have found a harness that painless makes that i believe i can get to work with a few changes, but my pockets are empty for the next few months.
