Things to check before first time spray!
Take a wire and temporarily hook it to the point where the relay wire feeds the solenoids. Hook the wire to any 12v light bulb you can pick up at radio shack or the auto store. Hook the other bulb wire to ground. Tape the bulb to your wind shield or put it some where in the car where it is easy to see when you are driving.
Take the car out and arm the system. Floor it below your window switch turn on RPM. When it gets to the turn on rpm the light should come on and it should go off when you hit the turn off rpm and when you lift off the throttle.
If the light does not go on and go off when it is supposed to you have a problem to fix before you spray. If you have a FPSS you will need to put a jumper wire on the terminals or hook both wires together for your test. This way you can safely test the system before you try to use it.
I liked this so well that I put a small LED in my pillar pod next to my nitrous guage. If I ever have a problem I will instantly know if the solenoids are getting power or not.
Excellent wiring and ideas....well done, I will definitely do this when i get my kit and drill a hole for a a nice blue LED on the pod

Agree. Doesn't matter that your trans is new. If it's stock, many components are simply not up to handling that kind of power.
I rather build the tranny up to the max and spray through shifts. Cutting off at shifts sets you up for lean spots, etc. And that, as calongo said, is not nice to your motor.
