I am going to install a set of driving lights behind the grill of my 02 ram. I want the lights to come on and off with the high beam lights. I can't seem to figure out which wire on the headlight is the high beam. They all seem to have power to them! Maybe because the daytime running lights are always on when the truck is moving. Maybe i have to go to the switch on the steering wheel (low/high beam)? Any help would be appreciated.
