Gauge question

[Stumbaugh]

I installed a nitrous pressure gauge the other day in my car and never got around to hooking up the light. I was wondering what I should splice into for the light to work. I dont want the light on the gauge to turn on every time I turn the car on itself. I would just like the light to come on when they gauge cluster itself is lit up.

You want a switched 12V power source. The headlight switch would work.

I would right to the wire for your dash lights comming off the headlight switch.
