Nitrous with a 4spd

here is where im screwed too...i was going to run a switch for my two step and line lock on my shift knob and was thinking of putting a button on my steering wheel for the nitrous...however, i didnt know you would have to let off the button on a stick car with the nitrous while shifting gears, and i dont know how easy it would be to let off on the button on the wheel...

correct me if im wrong but a window switch basically limits the rpms that the nitrous can activate- you can set a low and a high, so say you set the low to 3k and high to 6, the nitrous will not be able to activate any lower or higher than those rpms....
