The servo right? I have a pic on 2nd page of this post, Diagrams must be inside unit. Ok I have two more pics .of the wires ,main vac line, placement of the servo three bolt attachment area n opening though fire wall we're all passes though , now after unravelling tape around wires I noticed wires looped in harness with only two that would end up hooking to regulator , I wounder if some one had tried to hook the cruise up after it came from GM would they have used so much wire and loop it in the harness ??
