hey,quick question i just wanted to know which 1 of the three wires on the tps sensor do you tap in for the full throttle switch for a zex dry nitrous kit thanks.
The middle one 
No, but seriously, one wire is a ground, one is always 5v and the other one changes based on how much throttle you have. Use a multimeter if you can’t find a wiring pinout.
My guess is that its the green one…
green/wht = ground
red/blue = signal
yel/wht = 5v

the middle one but be careful if you are using t- taps . on mine it cut through after a while and it started to throw a tps sensor check engine light .
Damn! I lose
