I got the zex dry kit and am having problems with the install. I ran the black wire (-) from the NMU unit to a ground already in the engine bay, the white one to the corresponding white one on the TPS , and the red one i ran to the switch and then to the red/black ACC on the ignition. I listen for the solenoid to click when I step on the gas (WOT) like the instructions say to, and nothing. Theres a button on the side of the NMU with an LED under it . the instructions say nothing about it. Is there anyone with this kit that can help or has had similar problems? Or has any suggestions on wiring how toos? Ive searched several forums too no avail.

 

I have the Zex dry kit also, and you run the red wire to the switch and the black wire from the switch to the positive side of the battery. I have a system in my car so I just spliced mine in with my amp wire. And the button on the side of the box is the reset switch. When you turn the key to the on position without starting it and turn the nitrous switch to on, the light should come on..if the light is red, turn the key off and press that button, then turn the key and the switch on. If the light is green you are good to go.

 

Thanx for the help, it works now
