For some reason, I cannot find any wiring diagram for the GM 3-Pin Style TPS. It's the same sensor that DIYAutoTune sells; matching wires and all. I don't know the function of each wire, however. I assume black is ground, but that still leaves me with the blue and gray wires. Which is power and which is signal? Help?
Blue:
Gray:
Black:

GM uses Grey as 5v and blue as signal return. Black or orange/black stripe is sensor ground.
