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?

 

Nope. If you turn the Lock-Out off it should come on at 3K as long as u have it in 4 cyl mode.

 

Are we supposed to use this switch in 4 cylinder mode? Thanks.

 

Yes, switch to 4 cylinder mode and use the NX wiring diagram below if you have the NX kit.

 

Thanks! I appreciate it!

 

i haven't messed with mine, install in a few more weks. But WHY do we set it to 4 Cyl. Mode?????????????????????/

We have an 8???

just curious

 

I read that you have to do the same with the MSD window switch, i.e., use it in 4-cylinder mode. I believe it has something to do with the way our ignition systems are setup.

 

Simply turn your main nitrous switch off and if hooked up correctly the GREEN light will come on at pre set RPM while revving up motor. I compressed my activation switch at gas pedel by hand while doing this test, but you may not have to do this for the green light to turn on.

 

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.

 

Got mine working. It wasn't set in four cyl mode!

 

Glad to hear. Let us know if you got any more ?'s or problems. Posting or PM'ng is the fastest way to get ahold of us.

 

Cool thanks for the help guys.
