On the throttle posistion sensor there is a black connector and a grey harness that goes off to the side. That harness has 3 wires. red, black, and white. I assume the white wire is the signal wire.
The signal wire is the wire that tells the ecu and\or tcu what the throttle position is (0v - 5v). I am trying to hook up my zex kit and i need to know which wire does what.
