Which TPS wire on a C5 for WOT switch? I know there is a similar C6 thread going but does anyone know which C5 throttle body wire to tap into for a nitrous WOT switch that reads voltage?
I do know that...
Dark Green/White = TPS 1 signal reference
Purple = TPS 1 ground
Dark Blue = TPS 1 signal
Yellow/Black = TPS 2 signal reference
White = TPS 2 ground
Pink = TPS 2 signal
...I'm assuming that I would use the TPS 1 set but not sure of the difference between "signal" and "signal reference". I know the WOT switch (Zex) looks at voltage.

I was using the one that NX ricky quotes (Blue wire)
04 GTO LS1 TPS at the throttle body BLUE wire. at the computer pin 24 grean seal connector 2. blue wire
TACH coil trigger wire light green passenger side, at the computer pin 10 green seal connector 2. brown wire
05 GTO LS2 tps at the computer pin 31 green for falling black connector. tps at the throttle body Green wire
tach coil trigger wire light green passenger side., at the computer pin 48 blue connector 1 Brown wire I believe..
Someone might want to check me on this.

I know this is really old thread but im running into this same issue. I wired a zex universal self contained kit into that blue wire and the when turned on and WOT the car goes into reduced power mode and freaks out. It spits a code and if I remember the code is something to do with low out put signal. (sorry i was working on it last fall and havent pulled it from storage.) does any of this ring a bell? or strike an obvious chord?
