Alright quick question about my throttle position sensor, first off I have a 91 z28 tpi. I had to buy a new male socket to connect to the tps. I took the old one off without writing down where the wires go it has three wires dark blue gray and black. I cant figure out which goes where. I think the black one goes on the bottom but i'm not shure and I don't know know about the other two. If any one could help me out it would be great. Right now my car is running like sh*# because I don,t have the wires hooked up right.THANKS FOR ANY HELP

 

BLK - 'A' terminal (Signal Ground);

BLU - 'B' terminal (TPS Signal);

GRY - 'C' terminal (+5VDC Reference).

I'm not sure about the orientation of the non-adjustable TPS sensors, but the adjustable sensors have the terminals designated "A - B - C" from the top to bottom. Your TPS should have the terminals marked.
