I have a quick question for this running a transbrake with a 2 step and nitrous. I have a window switch and a WOTS and im wondering if I am sitting at the line and I have my transbrake engaged and the 2 step engaged at 3500 rpm will it hold it their and allow me to have my window switch set for 4k and the nitrous engaged or is it going to bounce the revs to much and accidently engage the nitrous? Just wondering how you guys have yours set up for this kind of launch. Thanks for your guys helps so far. I am testing out a new setup and would like some pointers. I have not ran the transbrake with my gas yet. I have run each one separately though.

Most people just run their nitrous on a relay with the transbrake and a WOT switch. Wire up the WOT switch so that the nitrous only works with the throttle wide open, and then the relay goes inbetween the WOT switch's 12v source. When the transbrake is on (applying 12volts to the solinoid), the relay is closed not allowing power to the WOT switch, then as soon as the transbrake is released, the relay allows 12volts to the WOT switch. You have to wire the relay normally open.

So your saying to get a relay and wire it normally hot and then when I engage the brake that I should run another power wire to the relay to ground out the relay causing the WOTS to not have power?

The power for the nitrous wot switch comes from the relay. Thats why the relay is normally open and keeps the wot switch hot incase you footbrake the car, but when you activate the transbrake, it makes the relay open causing the 12v not to be sent to the wot switch, then you let off the transbrake button and the nitrous comes on. The 12volts going to the transbrake soliniod is what you run to the relay also to make it open the connection when you hit the button.

This is how I have it wired right now. Can I use the relay I already have in the system? Do you happen to have a wiring diagram I could use to go by. Thanks for all your help!

I found a diagram of a relay and just modified it a little bit. I'm no expert, but this should work.

Looks to me like i should be able to install this relay in between my RPM window switch and my WOT switch. That would interrupt the circuit until I let go of the transbrake button. Sound right? Like this then.

Aslong as you break the main power circuit feeding the wot switch when the transbrake button is pushed, it will work.
