Harlan Window Switch question green wire will go to my tach
black wire will go to any ground ground
those I know for sure...now for the ones I'm not sure.
red wire will go to a switched 12v? like could I splice it into my arming switch?
and the white wire will go to the ground of the relay?? does that replace the ground from the relay, as in I take the ground already on the relay out and replace it with just the white wire from the window switch? And how does that diode fit in?

Well this is what I did but I have not yet checked to see if it works.
I hooked the green to the tack, the red to a switched 12v source, the black to a ground, and...
the white to the ground of my wot switch, and no use of the diode. Will that work? as in when the rpms are within my range, it will give the wot switch ground and start to spray as long as the nos is armed??

So even though I have the white wire going to the wot switch, I can still have have problems without using the diode? Am I suppose to hook up the diode even though I have nothing connected to the relay from the window switch?

Yeah, it wasn't hard at all to hook up, I just didn't understand how it operated so I was confused on how to hook it up so I wouldn't sell it if I were you. I just had to realize it just throws the ground at certain rpms. I haven't used it yet because I have no nitrous. But I took the ground off of the wot switch and cliped a test light to it. Held the needle to a 12v source and went for a drive. Everytime I hit the min rpm the light came on so I know it's working. Didn't test the upper rpm but I assume it's working.
