Fifth Wheel Wiring Harness Installation - 2014 GMC Sierra 2500- Video
Today on our 2014 GMC Sierra, we'll be installing the Bargman fifth wheel Gooseneck 90-degree wiring harness with seven-pole plug, part number 54701-003. We'll go ahead and choose a location to mount our seven-way plug. I know we need to put a pilot hole through the bed. We're going to make sure on the back side that there's nothing that could be damaged. Once we have our quarter-inch pilot hole drilled, we'll come back with a two-inch hole saw. Now we'll take our end of the wiring harness that has two plugs on it and feed it to the hole we just drilled. Now that we have our wires fed down through the two-inch hole, we'll go ahead and take a small drill bit and put a pilot hole into each of the four mounting locations on the plug. Once we have a pilot hole on each of the four locations, we'll go ahead and put the self-tapping screws in place securing the plug to the bed of the truck. Now we'll go and take the end of our wire and route it over into the back of our factory seven-way plug. Now that we have our wires routed over to the backside of the factory seven way, we'll need to unplug the factory seven-way plug. To do this, we'll remove the small gray locking tab. more
