Default Trailblazer ss guy needs help. ASAP

This is for a trailblazer ss with the LS2. this guy on a trailblazer ss board needs some help with a question. post up and i will forward it to him. Thanks.

"I have started to install my nx kit on my tbss and I have run into several things that have me puzzled. I am not sure which wire on the throttle body positioning sensor I need to tap into for my window switch. I have been told the purple one but I want to know for sure. Also needing to find the right line to tap into for the tach signal. I have pulled the tape on the passenger side by the coil packs and have been told its the green wire i need but again I don't know for sure. And maybe a easy 12v. accessory switch on the inside of the truck if anyone knows that also. Thanks in advance."

whos window switch.
If the Trick switch
tach is green/white stripe
on the TPS you have a purple and a green on is rising one is falling. tap into either wire and check it, with your window switch. You will know right away.
I like the falling signals better.
rising works but can be a little tempermetal.
hope this helps.
Rick

I still can't find a tach signal. I have tried two wires and still nothing. If the window switch doesn't find a tach signal will it not let the system work at all?
