Hello, i have mostly been in the engine category of this site, i am hopping up my 350 and i just put in a th400 that was from a 79 truck with a 454, i put a stage 2 shift kit in it aswell, but i didnt know how to hook up the over drive, i saw the wire from the drivers side on the tranny, but i ddint want to screw anything up. Is it just a 12v source or do i need to do soemthing different. I also just put in a hurst pistol grip shifter, and i love it. i am puttin in a 2000 stall torque converter as well. but i wanted to know how to hook up the overdrive? Any helpo would be hugely appreciated. Thanx Marc
