Hey got a question, I recently bought glow-gauges and when im installing the gauges there is a red wire, where does it hook up into the fuse box? so that when you turn on the lights, thats the only time that the light illuminates.

 

All you would need to do is to wire them into the hot wire, or into the stereo switched hot wire. So when the ignition is on, the gauges are illuminated.

Or, if you have a factory wiring diagram, wire them into the power source that the OEM gauges use.

 

if u only want them on when ur headlights are on then u need to find the parking lights wire so anytime ur headlights or parking lights are on then the gauges will light up. otherwise just find a wire that is hot when the key is on like miracle says
