terbear4god4life #1 how would i hook up a single led to only turn on when my zex computer is pumping nitrous?? "she can polish my strut bar anytime As long as her blow-off valve's in good order"
Hanyo #2 run a wire from the positive side of the pump to a resister then to the led. Ground the other lead of the led to a clean ground. This way when your pump see 12volts so does the LED. They both will turn on at the same time.
