N2O setup ??????
I have a NX kit for my car. It has all the goodies with it kit,purge,heater. I am getting a window switch with TPS activation on it. MY question is this-I misplaced the relay that comes with the kit. Do I need to run a relay with the Window switch or will I be OK without one??
NOPE! the relay is for the solenoids. the amount of current (AMPS) the solenoids will pull will most likely fry any switch or component that’s wired in with it. the switches and components trigger the solenoids with will then pull current (AMPS) strait from the ground wire to the positive 12v source (battery). Most small solenoids pull around 25-35 AMPS.
