I need to splice into my throttle position sensor out put wire for my zex wet kit...there is 3 wires in the TPS. One is black and obvisously ground, but is the green or yellow the out put one?
Thanks
Bill

 

TPS should have

black = ground
drk blu = TP sensor signal
gry = 5v reference from pcm

 

Using this picture http://csce.uark.edu/~jgbertr/rb/tps.jpg to see my TPS, when i look at mine in my car, the wires are differenct colors. Mine are black green and yellow. Did GM just run out of wires to use?? I need to hook into my out put signal so zex calls it, should i just splice it to the yellow wire?

Don't worry about the wire colors... look at the "position" on the plug. On Rob/Shoebox's photo, the black and gray wires are postioned on the "flat" of the connector, against the clip. The blue (variable output) signal wire is alone on the other side of the triangle. That is the wire you want.

 

OK thanks, ill try that.
