I guess now I have to try and figure out how to hook it back up to OE??
do you have a mity-vac?
you can run the engine and check it with an ohm meter, at idle it should have continuity (contacts closed), rev the engine and the contacts should open. Mine, IIRC, has 2 green wires. one wire goes to the brake switch and the other goes to the transmission.
do you understand how it is supposed to work?

TH350C?

I have a 350C in my '80 and I just recently hooked it back up, so if you have any specific question let me know
