Ive searched with no definite answers, but
Has anyone tested to see if while using the mallory 2 step function, does this disable the window switch?

 

I did not actually test that and wondered about it myself but I just used a relay to make sure that the window switch did not cause the nitrous to spray until I released the transbrake(which activated the two step).

 

you will need to use a relay to cut power to the kit when you are on the 2 step.

here is a diagram showing the wiring for a trans brake...the 2 step would wire the same way
