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 10'. It is compatible with 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.

The CURT 56001 10-Foot Vehicle-Side Truck Bed 7-Pin Trailer Wiring Harness Extension, Select Dodge Ram 1500, 2500, 3500, Dakota (Part #BKDK56001) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
Yes, part 56001 is designed for Dodge Ram and Dodge Dakota vehicles. However, your vehicle must have a factory OEM 7-way trailer connector already installed on the hitch or bumper. If your vehicle does not have this factory connector, this extension harness will not be compatible.
The 56001 is a 7-way trailer connector extension harness that allows you to extend your vehicle's factory trailer light wiring to a new location. It connects between your vehicle's factory wiring harness and the factory 7-way connector, routing the connection to a new mounting point (typically on the driver's side between the rear post and wheel well).
You will need: a hole saw (2 1/8" diameter), a file, a drill with a 7/64" bit, and a test light or properly equipped trailer to verify operation. The self-tapping screws and cable ties are provided with the harness.
The kit includes self-tapping screws for securing the 7-way connector and cable ties for securing the extension harness cable to the vehicle.
The manual does not specify whether battery disconnection is required. Contact the manufacturer or a qualified installer for guidance on this step.
The manual recommends mounting the connector on the driver's side between the rear post and the wheel well area. You should choose a location where the harness will not pinch or bind when the vehicle turns. Before drilling, verify that no miscellaneous items (fuel lines, brake lines, wiring, etc.) are hidden behind or under the surface where you plan to drill.
Yes. You must drill a 2 1/8" hole in the sidewall at your chosen mounting location, and then drill four 7/64" holes for the connector mounting screws. Before drilling, verify that no hidden items (fuel lines, brake lines, wiring, etc.) are behind or under the surface to avoid damage to the vehicle or personal injury.
Drill a 2 1/8" hole in the sidewall using a hole saw. After drilling, use a file to smooth the edges of the hole to prevent abrasion of the harness or connector.
The four mounting screw holes are 7/64" diameter. Use the connector as a template to mark their locations, then drill the holes and secure the connector with the self-tapping screws provided.
Carefully slide the red lock clip on the factory 7-way connector, then gently pull the connector apart while holding down on the connector locking latch. This will separate the factory connector from the vehicle's wiring harness.
Position the paired extension harness connectors between the vehicle harness and the factory 7-way connector. Insert the longer of the paired connectors into the vehicle's wiring harness connector, pressing firmly until the locking tabs engage. Insert the shorter connector into the rear of the factory 7-way socket, pressing firmly to engage the locking tab. Return the red locking clip to its original position.
Route the extension harness connector up from under the body through the 2 1/8" hole you drilled in the sidewall. Insert the harness connector into the rear of the provided 7-way socket, pressing together firmly to engage the locking tab. Position the 7-way connector into the opening.
Using the connector as a template, drill four 7/64" mounting screw holes. Secure the connector to the vehicle using the self-tapping screws provided.
Secure the extension harness cable to the vehicle using the cable ties provided. Route the cable so it will not pinch or bind when the vehicle turns.
Confirm harness operation with a test light or by using a properly equipped trailer. This verifies that all connections are secure and the trailer lighting circuits are functioning correctly.
Before drilling, verify that no miscellaneous items are hidden behind or under the surface where you plan to drill. Hidden fuel lines, brake lines, wiring, or other components could be damaged, resulting in vehicle damage or personal injury.
Smoothing the edges of the 2 1/8" hole with a file prevents abrasion of the harness or connector as they pass through the hole.
