BMN Window Switch Wiring ? I'm wiring up my window switch today and I was wondering were you guys connected the brown wire? Which is the one for the switched power side of the brakes. This is my last wire so any help would be great! 
Connect to the LIGHT BLUE wire at brake lite switch. The brake lite switch will have two wires connecting to it "LIGHT BLUE and ORANGE". The switch is located under dash and is activated by the brake peddle.

Thats the right one thanks. I have one more question about the test LEDs it says "The GREEN LED will illuminate when the nitrous oxide is ON in your RPM "Window". So that means the only way to test and see if the window switch is working is to start the car and run it and see if the light comes on after 3000 rpms at wot? Does the nitrous have to activated also?

Just the way GM does it. The tach signal comes out of the computer and goes to the gauge in a 4 cyl frequency. They could program it to come out in whatever cyl mode they wanted. like 1,3,5,6,7,8,10, whatever. You do get a more accurate messurement from a 4 cyl signal.
