#43492, "Zex Nitrous Kit- Where is the TPS located?"
A buddy and I recently installed the zex universal kit for his 97GS. There are three wires comming off of the throttle body. We were told that the TPS sensor needed to activate the unit comes off one of those wires. After checking the voltages of each wire against the voltages when the throttle is at WOT, we came to the conclusion that the TPS lead is the red wire.
Here is where it gets interesting. After taking a test run in his car, we found that his nitrous is activating when you throw the activation switch. Those of you that are familiar with the zex kit know that it is not supposed to activate unless you have your foot to the floor and at the WOT.
My question is, what did we do wrong? We suspected the NMU is malfunctioning, or we could have the wrong wire. Can someone with expecience with this kit give a little bit of insight.
