On my work truck, i wanted to hard wire this because i tow a trailer often. Constantly plugging and unplugging would be real tough on the wires. Let along damage to dangling wires from job sites and loading unloading. I cut off the 4 pin and got under the bumper with a 3/16 hole i drilled into the utility bed rear driver tool box. Only to find the wire coming off the light bar is different colors then the diagram. I need to know what the red, black, yellow, and green wires connect to the vehicle's yellow, green, brown and white. And on my vehicle there is a blue wire in the harness.
