Alright quick question about my throttle position sensor, first off I have a 91 z28 tpi. I have a new male socket to connect to the tps. I took the old one off without writing down where the wires go I have 3 wires DARK BLUE, GRAY, and BLACK. I can't figure out which goes where. I think the black goes on the bottom but I'm not shure. If anyone could help me out it would be great. Right now my car is running like sh#% because I dont have them hooked up right. THANKS
