I am installing some kc windshield mounted lights and can't for the life of me figure out how to get my green and white wires into the cab so I can connect my switch. I've read about a grommet somewhere above the gas pedal. Can't find that one. I also saw there is one if you take the side panel on the dash. Can't find that one either.
If its easier to drill through the firewall where is the best place?
