Hi Jerry
There is a whole lot more switches, relays and etc. WOT relay, AC cycling switch on the accumulator, Dual pressure switch and the PCM have to all be in the correct mode before +12 v energizes the clutch. You sound ambitious and willing to learn. "PM" me your e-mail and I'll send you a couple of pages out of the Mitchell's Wire diagrams. I don't have the manuals but I made a couple of copies from my library. I'll scan them in if you like?
