Nitrous Works includes a microswitch to activate the spray at full throttle. Unfortunately, they didnt include any hardware to fasten it to the tapped holes in the nitrous plate, so we hit up the hardware store for a couple of M5 screws and lock washers. Youll have to play with the bracket a little to ensure that it activates the N2O only at full throttle. We ended up bending the switch bracket slightly outward to get it perfectly fitted. The switch contacts this cam (arrow) when the pedal is floored.
