throttle position sensor wiring
Just put the 350 in and I have the Holley 670 TBI unit and it uses the older flat style connector on the TPS. My car's wiring harness uses the round new style connector. The pigtail I bought to wire in to my harness has an A, B and C on the connector, I need someone to tell me which wire from my harness goes to which on the old style connector.
I currently have it wired up like this and its givng me code 21 which is TPS voltage too high at idle.
Gray wire = A
Black = B
Blue = C

Your wire codes should be as follows.
Pin "A" = black (sensor ground)
Pin "B" = dark blue (TPS signal)
Pin "C" = gray (5 volt reference)
