wiring for torque convertor lockup on 700R4 transmission
I have a 700R4 transmission from a 1987 Camaro. It is hooked up to a 1988 305 Chevrolet engine and works fine. It was just overhauled complete with a new torque convertor. I need to wire up the convertor lockup. I have a new plug for the transmission. I want to hand wire it without buying a kit. I also will need a to get a vacuum switch to kill the lockup when operating conditions call for releasing the lockup. I have a basic knowledge of how the system works, I'm just am not sure which pins to hook up to. Thanks for your help. Skyraker

I would run 12V to the + side of the tcc solenoid and run the other side to the 4th gear switch for ground.

tcc will come on right on top of 4th gear but it will work
