I took this kit off a car I parted out with no docs for the window switch. NOS Wet plate kit. I have everything basically wired and installed but the window switch.

On the window switch, I have +12, ground and a tach line pretty simple. I have two more wires, one is grey and was tied off and not used. The other one dont recall the color. Where does that single wire go? It doesnt seem logical I should have two wires and it should work like a switch correct? It doesnt seem logical that one wire would do anything its all wired in series.

I have TR6's in the car and a nitrous cam upgrade pump blah blah. How much timing should I pull for a 100 shot? I dont care if it slows me down a little NA.
Thanks
Jay
