I have a 98 z28, I am wiring up my window switch. I have all the wires hooked up and tapped into the white wire on my computer ( the tach ) when I start my car I can see the little L.e.d comming on the window switch, then with the car running i will just hit the wot switch and the noids will click???? I have it wired up right. Am I not tapped into the right wire for the tach? I put a light thats supposed to turn on when it gets 12v Im puttin it where the ground from the nitrous kit connects with the window switch, I know the window switch is comming on, i hold down the wot switch, rev the car to 3000 and nothing??????

*the window switch im using is a Harlen window switch

Here are pics of where I'm taping into the computer




Please please help I have no clue?

 

97/98 LS1'sshould be the upper connector pin #35.
99+ is the lower connector pin #10.

 

pin #35. on the upper. what color wire is this or how do I find it by the pin?

 

you should be sable to see some # on the connectoe itself.I cant remember if you have to take it loose to find them but i think thats what I did.

 

Should still be white.

 

I found the white wire but its located on the lower pcm. Is this the right wire
