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 CURT 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 or trailer hitch. 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. These CURT extension harnesses are designed to work with 7-way RV blade connectors and come with 7′ of wire. Ten harnesses are included in each package. They are compatible with 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, CURT gets you plugged in.

Product Features:
  • Routes a 7-way RV blade socket into truck bed while retaining use of rear socket
  • Simple plug-and-play design eliminates the need for cutting or splicing
  • Allows for easy connection of 5th wheel or gooseneck wiring
  • 7-way connects tail, brake, reverse, turn signals, brakes and auxiliary power
  • 7′ extension with right-angle plugs for easy installation
  • Spring-loaded dust cover keeps connector clean when not in use
  • Slit loom keeps wires contained and well protected

CURT – Replacement OE 4-Way Flat Socket (Plugs into USCAR) (Part No.55515)

Replacement OE 4-Way Flat Socket (Plugs into USCAR)

from

$30.99
A CURT custom wiring connector (sometimes called a T-connector) is a simple, plug-and-play electrical device that eliminates the need for cutting, splicing and soldering when installing vehicle-to-trailer wiring. Most vehicles do not come ready to tow. Unless your vehicle has a towing package, it is probably not equipped with a trailer wiring connector. This is where CURT’s custom wiring connectors come into play. A custom wiring connector uses a single original equipment plug to plug into a special socket provided by your vehicle. Though this option is not available on every vehicle, some automotive manufacturers design their vehicles to be easily equipped for towing by supplying a socket, integrated into the vehicle’s electrical system, to readily accept a custom wiring connector. With a CURT custom wiring connector, there is no need to tap into the taillight assembly because a special socket is already provided. This custom wiring connector provides a 4-way flat connector socket and is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle). CURT custom wiring connectors are designed to be long-lasting and simple to install. They come with dust covers to keep your connector clean when not in use.

Product Features:
  • Plugs into USCAR socket to provide 4-way flat trailer wiring connector
  • Simple plug-and-play design eliminates the need for cutting or splicing
  • 4-way flat output connects tail lights, brake lights and turn signals
  • Dust cover included to keep connector clean when not in use
  • Slit loom keeps wires contained and well protected
  • Backed by a limited one-year warranty
