Our power ground and light wire end up under the left side of the dash near the steering column. The brown ground wire is screwed onto a cleaned area under the kick panel. It's important to get a good ground. Typically, the dashboard is not a good place to attach ground wires.
The power wire needs to be connected to an ignition key "on" power source. Robert has chosen to tap into the large pink wire coming down the steering column (blue arrow) from the ignition switch (pink arrow). The red wire from the window switch harness is soldered onto the large pink wire and the connection is taped up. Robert has also used a wire tie over the tape to insure that this connection will last as long as the truck. A soldered splice makes the best electrical connection possible and should be utilized whenever it is possible.
The light wire is brought out to the left front headlamp assembly and connected to the parking lamp circuit.
