Default Nitrous Window Switch Help

On an 05 C6 Auto:
Which wires on the ecu to tap into for the window switch?

Also, is it easy to install the fuel pressure switch?

At the SoCal C6 round up a guy had his nitrious switch wired to his hazard button. The install on his system was extremely clean done by WCC

White wire: pin #48 on the blue pcm connector. Be carefull of what you use to cut the bundle of wires open with....go slow and it will work. I tapped the window switch and the shift light at that spot. Set both for 4 cylinder operation.

Remember that the window switch provides a negative for the output not positive so the relay it drives should have the positive at it already and then the window switch will give the ground.

PM if you still have an issue. Also the pills are just resistors and you can approximate any value for the pills by the following:
rpm +1000= resistor value. Not so accurate in the upper rpm's but close enough to fool with....$1 for a bunch of them until you get it right

I bought the BMN WIndow Switch with 1st Gear Lockout.

It does not use pills. It is a dial.

Thanks for the info. Why would I want to set it to 4 cylinder op?

What shot do you have in your C6? Dry or wet?

Thanks!

The fuel pressure switch is easy but the calibration is a little tough if you get the cheaper nos one (you need to adjust it with an air pressure source for a pressure value under the GM fuel pressure level). It goes on the fuel rail with a fitting and it is wired in series with the relay from the window switch. Don't have it interupt the solenoid's power.

It is dry for now -C6: 80 shot- but I will switch to wet after I change the manifold.
C5 is wet progressive 125 shot.

You use the 4cyl operation mode because the tach signal at that wire feeds each of the coil pack sets separately. 4 coils, hence 4 cylinder.

Both my cars are juiced so its from experience I speak.

What FPS switch are you using?

Where did you mount your bottle? Can I mount mine sideways so I can still fit my roof?

Thanks for all your help!

Do you have any pictures of your setup

That is one nice set-up!!

I dont have any pics but the bottle fits in there with the roof panel. Just remember the bottle must be tilted and the correct orientation for the pick-up in the bottle.
