Product description

7-way RV-style connector design for use at your truck bed for quick, simple hookup of your 5th-wheel or gooseneck trailer. MECMO T-Connector is an extension wiring of the truck's existing towing line. 5th Wheel and Gooseneck OEM Extension Harness add up an additional 7-way socket of your truck beds while retain the use of your vehicle's factory 7-pole. 7-Foot total loom length, plug & play, for hassle-free hookup of 5th-wheel and gooseneck trailers. Includes zip-ties and self-tapping screws in the full package. There is nothing like the luxury and power that go along with heavy-duty towing. 5th wheel RVs offer a deluxe, home-away-from-home experience unlike any other, while gooseneck trailers possess a strength that far surpasses most other trailer options. As with any trailer, however, 5th wheels and goosenecks must be equipped with the proper lighting and electrical systems, and tend to require even more complex connectors than a standard receiver-type trailer setup. Make things simple with a MECMO 5th wheel / gooseneck extension harness. These wiring harnesses are designed to put an extra connector socket in the bed of your pickup truck while still retaining power to the rear connector socket mounted on your bumper. This is done by plugging into the back of the existing original equipment (OEM) harness and routing through the body of the truck to a hole in the truck bed, providing a connector that is ready to accommodate your 5th wheel or gooseneck trailer. This MECMO extension harness is designed to work with 7-way RV blade connectors and comes in a length of 7'. It is compatible with a certain models of Chevrolet, Dodge, Ford, GMC, Nissan, Ram and Toyota (see application to verify fitment). When you need a towing electrical solution that allows you to switch back and forth between your receiver hitch and specialized trailer hitch, MECMO gets you plugged in.

Used this to connect all my Backrack lights on my full size truck. Works great and doesn’t make your truck think it’s connected to a trailer which then usually disables some backup warning sensors and or blind spot monitoring. At least that what happens on my 3rd gen Tundra.

Fit 2020 Ford F150
Reviewed in Canada on May 28, 2025

Installed on a 2020 Ford F150 and worked like a charm. Application notes mention 2014 max, but other sources confirmed my 2020 used USCAR connectors just like this harness does. Nice heavy gauge wires on the ground, aux power and brake lines. Smaller wires for the lights, but still plenty big.

I did not use the supplied self drilling and tapping screws as I was concerned they might interact with the aluminum bed. Used some 3/16" x 1/2" long aluminum rivets to attach the connector to the box and worked great. The cable ties supplied were a little on the small side.
