For all the retards out there like myself who had a hard time figuring this out, i spent a few minutes drawing out the wiring diagram before i went and wired it in my car. anyways, what i did below worked for me. i wanted to 2 step the car at the line, line lock it to stage, disable the nitrous while on the 2 step, and instantly spray once i let go of the 2 step/line lock button. problem is my car has slicks and skinnies and i launch the car at over 3000, which is what my nitrous is set at to spray. while on the 2 step and having the nitrous spray = blown motor lol. anyways, i can now go WOT, 5500rpm launch, stage with the line lock, and instantly spray right off the line. takes off consistently like a bat out of hell. i have tried my 'plan B' but i don't see why my 'plan A' wouldn't work.

Please let me know if there is a better way to do this. However, my 'plan B' seems to work for me. Sorry for the crack head drawing

 

Here is a diagram that i had
