Harlan 2-step install? Wasn't sure where to put this, but there's three wires on there, gray, white, and yellow. Which wire is for power, which is for ground, and what the hell is the third wire for? I am going to hook it up so that it always has power, but the ground is going to be controlled by my transbrake button. I already have a relay that when the t-brake button is pressed, it takes the ground away from the nitrous solenoids and will give it to something else, that something else will be the two step, so which wire for power, and which wire for the ground into the relay? Thanks for any help!

Ground the gray wire permanently, and apply ground to the white wire when you want the 2 step active. If your existing relay will do that, you're golden.

Thanks a lot dude!!!! 
One other ? though, what would be a good starting point to set it at, like how many rpm before full flash on the t-brake?
