Well im wiring up my lt12s unit, and I've ran into a little issue on which wire is which for the s1 TPS.. I need to know what color is the 5v, TPS signal, and earth.

we have in order if looking at the clip side of the plug a yellow wire, red-black wire, blue black wire.

Im guessing the blue black is the 5v, signal is the yellow and red-black is earth, Just would like to verify.

thanks guys.

yeah I took a look at that already figured out my CAS that way, but the TPS is just not lining up as far as wiring colors are concerned. not to mention that diagram doesn't have the power, gnd, or 5 volt labeled.

I see the one wire goes to the shielded ground. the other goes up to the coolant temp sensor, and the one goes up to the other top pin in.

any other help?

I think I figured it out... red/blue wire is +5, yellow/black is signal, black/blue is ground.

anyone confirm?

No.. If a wire is shielded it is almost always a sense wire so R/L = sense.Only the Ecu provides a 5 volt output so from the diagram Y/B = 5 volt inObviously B/L is now ground.

R/L= Red-blueY/B= Yellow-blackB/L= Black-blue
