I have a 99ss with a harlan two step and a nx single nozzle efi wet kit and a th400 with a tbrake. I want to be able to have them wired all in sync. I want to be able to press the transbrake button and have it also activate the two step and disarm the nitrous so I can release the button and launce off the brake and disarm the twostep and engage the nitrous. I have a tps activation/WOT switch with a window switch set at 3k. I have the nx 3 button switch panel. My trans brake has no relay, just two wires, one grounded and one 12v to a momentary switch.
Any help is appreciated. Thanks guys.

 

See the "Nitrous Related Wiring" thread in the stickies at the top of this forum, there are a few diagrams there.
