Very strange. Not sure how yours is hooked up, but that seems so weird.

I've heard the window switches are real finicky, though.

I'm going to try one, too (modified by MSD to work with the coil-on-plug ignition), but if it gives me trouble...its gone.

I plan on arming my system, but activating it with a button on the shift knob I made. This way it will only kick in once I've achieved traction. No sense in activating the nitrous and blowing the tires off.

Cool button I was try to think which way to do something similiar. Thanks for the pic.

Thanks! I just picked up my kit today and will begin work on it...although it will be a slow process. I want it done _perfectly_ and this is my first go-round with a late-model GM product.

I have a nice switch panel for it, but I need to figure out where to mount a real stealth bottle pressure gauge. Thinking of getting rid of the cig. lighter in the ashtray and putting on there.

Just a bunch of small logistics have to be taken care of it I want it to be as clean and tricked out as possible.

I can walk you through on the button/shift knob if you need some direction there. Honestly, it was very easy and didn't take much time.

I hope you have a safety switch mounted somewhere.... To me a button on the shifter is real easy to accidently hit.

I appreciate the concern. I really do. I have built in plenty of safeties. I ran a setup like this on a '96 Cobra I had for 2+ years without a hiccup.

There's an arm switch that has to be ON for the button to be live at all. There's an RPM window switch that has to be ON for the button to be live. There's a full throttle switch which has to be ON for the button to be live.

Plenty of safety.

I did it this way so I have full control over when the nitrous actually kicks in. Using only a WOT means you can't go full throttle in 1st gear without the nitrous coming on and subsequently lighting up the tires...unless you want to be fumbling for the arm switch during the heat of battle. Also, what happens if the road is cool and the car isn't going to hook up on the nitrous in 2nd? Well, I don't want it coming on then either.

In fact, there's a good possibility that I won't be able to use the nitrous effectively til 3rd/4th gear. Thus the reason for the button. All of the other 3 things have to be in place, and THEN the button has to be depressed for the nitrous to activate.
