I am in need help installing my zex system. I got all the wires wired up right all the hoses in, and everything done. I am haveing trouble with the TPS sensor. I think its the red wire in the middle, but when i put the cars key in second position and press the gas pedal to WOT, i hear no clicking from the zex unit?? Its not turning on, yes the system is armed. What is this from, and should i try other wires on the TPS? I have a 92 teg ls.

 

Do you have enough nos in the bottle

 

i have the bottle off, it says to test with pressure off to hear the clicking noise, you think that, the n2o off will do that?
