best place for gauge dimmer?

[rcLord510]

Hey everyone

So i'm going to be installing a glowshift boost gauge in my 03 gtp, and this gauge has a feature where one of the wires can be connected to the dash light dimmer and it will dim it with that switch, and i'm just wondering, what wire should i be using for that dimmer? As well as does anyone know the best place to get ignition power from inside the car, like so the gauge only turns on when the ignition turns on? Sorry if this is a dumb question, i'm new to all of this

Get a service manual set for that vehicle.  Wiring diagrams should be included.

An incandescent test light, or a voltmeter would pick out a fuse that's switched with the ignition.

Thank you sir, that was the plan, at least for finding the ignition switched fuse, but the service manual will be helpful for the dimmer
