I wonder if the two 12v power is like say a stereo. One is a constant hot and one is ignition hot. If both were constant hot, you would be able to arm the nitrous with the ignition key in the off position.
Looking at the diagram, makes it look easy, until you say your relay says 55,56,57,57a, etc...
Hmmm... Is this a brand new system or did you buy it used? Where at in Illinois you located?

I don't know where they came up with the numbers, but those numbers are common on relays (of this size anyway). The difference between the 87 and 87A is whether the output is normally hot or normally cold, 86 is the trigger hot, 85 is trigger ground, and 30 is the relayed hot. (I think, but you get the idea... it has been awhile since I have done anything with relays like this)

Ok my question is which number goes to my solenoids and which goes to my throttle activation switch and which goes to the non fused 12v since it looked like 30 is fused 12v from my battery
