Wiring a fifth-wheel or gooseneck connection doesn’t have to mean cutting into factory wires. The Pollak 5th Wheel / Gooseneck T-Connector with 7-Pole plugs inline with the existing factory harness to add a 7-way socket in the truck bed. It uses a standard round U.S. Car connector, so the install is simple and secure with no splicing required.
With this T-connector, you can keep the rear bumper plug and add another 7-way inside your bed. That means you can hook up your fifth wheel or gooseneck trailer without draping cords over the tailgate. The harness provides full power, brake, reverse, and light circuits through its 7-wire design for clean, reliable in-bed connections.
Each circuit uses dedicated wire gauges for strength and consistent current flow—8-gauge for ground, 10-gauge for brake output and 12-volt power, and 12-gauge for the lighting circuits. The back of the socket is sealed with silicone to keep moisture out and protect contacts from corrosion, helping ensure long-term performance even in wet conditions.
The connector mounts through a 2 or 2-1/8 inch hole in the truck bed wall for a factory look. Once the hole is cut, feed the harness through, secure the socket with the included bracket, and plug it into the OEM wiring. It’s a clean setup that keeps your wiring protected and out of the way when towing heavy loads.
