need help quick, i can't get my window switch to work I'm really pissed off at the moment, first i tried a NOS window switch my cousin had laying around free right but i wasn't sure if it worked. I wired it up and it wouldn't work. Now if i took the on pill out an put a jumper in there the system would work but if i put an RPM pill back in it, it wouldn't work.
So i go buy an MSD window switch, i found a few different ways to wire these things up on here so i tried another way AGAIN it would not work. And again it would work if i put a jumper in place of the on RPM pill. It's like it's not seeing the tach signal and i have the wire running to PIN 10 on the PCM. I cut that #10 wire just to see what would happen and the car started and all the gauges worked the only thing that didn't work was the TCS light came on is that right? If it's a tach signal shouldn't it affect the tach in the car?
Can someone throw me some help please i dunno what else to do, also i have an early 99 so i thought maybe the tach signal wire was where the 98's were......Nope there's no wire in pin 35 at all

Figured it out from some research, i know you have to wire an aftermarket tach in an LS1 ignition as a 4 cyl. so i cut the red an blue wires on the switch so it was a 4 cyl. switch. That and the yellow wire from the window switch can only handle 1.5amp's apparently the FPSS puts out more then that and by some luck i bypassed it and it worked amazing i kinda feel smart now

I didn't bypass the yellow wire i just bypassed the FPSS. What kinda window switch are you using. I tried my cousin's NOS switch but there was no setting on it to make it for a 4 cyl. so it would have never worked.
Here's a diagram of how i wired mine since it wouldn't work the window switch connected directly to the FPSS.
