That's what I am looking for! I really just want to switch the 71 body onto the 94 frame and use the computer for engine and trans only and keep the 71 parts separate. I have checked the use of the 94 firewall and it seems to be a mountain of work with very few benefits. If you have some reference sites or should I go to wiring diagrams? I'm not the best with electrical so any help is very much appreciated. Thanks
