I'm installing gauges and I need to know which wire to tap my dimmers into. The instructions call for the headlight wire. It's not the dimmer wire. The gauges power up full brightness and dim when 12v is applied to the white wire. I want that to be with the headlights not the parking lights. I run my headlight halos off the parking lights and run those often. So I want full brightness during the day when running the parking lights. Any help would be greatly appreciated. :top:
