I have all the obvious needs covered like the automatic column, linkage, shift indicator, radiator, trans lines, TV/detent cable, drive shaft. The transmission came out of a 1987 C10 and going into a 1986 C10 that was a stick shift. My question is what is involved with hooking up the electrical on the 700R4 to my 1986 which I am pretty sure that plug isn't under the truck. The loom is still in the 87 but it was a TBI engine. I desire to make it work like it is supposed too with the lockup if at all possible. I also have a 1986 C10 if I need to get the wiring off of that but I want to understand what it is and how it works.
