Trailer Wiring Kits for Your 2004 Dodge Ram 1500

CURT – Custom Wiring Harness (4-Way Flat Output; OEM Tow Package Required) (Part No.55381)

Custom Wiring Harness (4-Way Flat Output; OEM Tow Package Required)

from

$42.99
If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness — also called a T-connector — is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Chrysler Aspen and Pacifica, Dodge Dakota, Durango, Dodge Ram 2500, 1500 Van, 2500 Van, Dodge Sprinter 2500 and 3500, Jeep Commander, Grand Cherokee and Liberty and Mitsubishi Raider (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination — maybe it’s the boat landing at your favorite fishing spot, maybe it’s a campsite that overlooks one of nature’s masterpieces, or maybe it’s the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

Product Features:
  • Plugs into vehicle tail light assembly to provide a 4-way flat socket
  • 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

CURT – 7ft. Custom Wiring Harness Extension (Adds 7-Way RV Blade to Truck Bed) (Part No.56071)

7ft. Custom Wiring Harness Extension (Adds 7-Way RV Blade to Truck Bed)

from

$98.99
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. 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 CURT extension harness is designed to work with 7-way RV blade connectors and comes in a length of 7′. It is compatible with certain years of the Dodge Ram 1500, 2500, 3500 and Dakota (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 plug for easy installation
  • Spring-loaded dust cover keeps connector clean when not in use
  • Slit loom keeps wires contained and well protected
