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 certain years of the Ford F-150, F-250 Super Duty and F-350 Super Duty (see application to verify fitment). For trucks with an aluminum body, galvanic corrosion can become a problem when installing vehicle-to-trailer wiring without the appropriate protection. This kit includes isolators that allow you to install the wiring harness extension in an aluminum truck bed without having to worry about ruining the truck's finish. It includes four bolts for secure mounting and four plastic well nuts to isolate the fasteners from all aluminum surfaces.

The CURT 10' Custom Wiring Extension Harness (Adds 7-Way RV Blade to Truck Bed, Packaged) Trailer Wiring Adapter Connector (Part #BKDK57010) fits 2015-2026 Ford F-150 models. The 2026 model year is the last year covered by this part number. For newer models, check for an updated version.
Yes, the CURT 10' Custom Wiring Extension Harness (Adds 7-Way RV Blade to Truck Bed, Packaged) Trailer Wiring Adapter Connector (Part #BKDK57010) is designed to fit the 2015-2026 Ford F-150.
The CURT 10' Custom Wiring Extension Harness (Adds 7-Way RV Blade to Truck Bed, Packaged) Trailer Wiring Adapter Connector (Part #BKDK57010) Typical installation time is 30-60 minutes. Basic hand tools are typically all you need.
The CURT 57010 is a 7-way trailer connector extension harness that extends the reach of your vehicle's factory trailer wiring. It allows you to connect a trailer to your truck when the factory connector location is inconvenient or inaccessible. The extension harness pairs with your vehicle's existing 7-way connector and provides a new connection point mounted on the vehicle sidewall.
The CURT 57010 is designed for trucks with a factory 7-way trailer connector wiring harness mounted to the hitch or bumper at the rear of the vehicle. If your truck has this factory connector, the extension harness will work. The manual does not specify which truck makes, models, or years are compatible, so contact CURT Product Support at 877-287-8634 or visit curtmfg.com to confirm fitment for your specific vehicle.
No. The CURT 57010 extension harness is designed to work with vehicles that already have a factory 7-way trailer connector wiring harness. If your truck does not have this factory connector, this product will not function. Contact CURT Product Support at 877-287-8634 to discuss alternative solutions for your vehicle.
You will need: a drill, a 7/64" drill bit, a 2-1/8" hole saw, a metal file, a flathead screwdriver, and a Phillips screwdriver. These tools are required to drill mounting holes, smooth the edges, and secure the connector to your vehicle.
The kit includes: one extension harness with paired connectors, four self-tapping screws for mounting, and eight cable ties for securing the harness to the vehicle.
Yes. You must disconnect the negative battery terminal on the driver side under the hood before beginning installation. Reconnect it only after all installation steps are complete and you have tested the harness for proper function.
The factory 7-way trailer connector is mounted to the hitch or bumper at the rear of the vehicle and is connected to the vehicle taillight wiring harness. It will look similar to the connectors on the extension harness you are installing.
Carefully release the gray locking clip on the connector. While holding down on the connector locking latch, gently pull the connector apart. Do not force it; the clip and latch are designed to release smoothly when properly manipulated.
Position the paired extension harness connectors between the separated factory connectors. Insert the longer connector into the vehicle wiring harness connector, ensuring it is fully inserted with locking tabs in place. Insert the shorter connector into the rear of the factory 7-way socket, also ensuring full insertion and locking tabs. Return the gray locking clip to its original position.
Locate a suitable mounting point on the driver side between the rear post and the wheel well. Route the harness to this location, ensuring it will not pinch or bind when the steering wheel is turned. The manual provides wiring location guides for trucks showing reference points (T1 through T5) behind taillights and bumper areas.
You must drill a 2-1/8" hole in the vehicle sidewall using a hole saw. This hole allows the extension harness connector to pass through the body. After drilling, use a metal file to smooth the edges of the hole to prevent abrasion of the harness or connector.
Before drilling, check for miscellaneous items that may be hidden behind or under any surface to avoid damage and personal injury. This includes wiring, fuel lines, brake lines, and other components that could be damaged by drilling.
You need to drill four 7/64" mounting screw holes. Use the connector as a template to mark the hole locations, then drill the holes using a 7/64" drill bit. The provided self-tapping screws will secure the connector through these holes.
After drilling the four 7/64" mounting holes using the connector as a template, insert the provided self-tapping screws through the connector into the vehicle sidewall. Tighten the screws securely to hold the connector in place.
Use the eight cable ties provided in the kit to secure the extension harness to the vehicle. Route the cable ties along the harness path to prevent movement, pinching, or binding, especially when the steering wheel is turned.
Test for proper function by using a test light or connecting a properly wired trailer. This confirms that all connections are secure and the wiring is functioning correctly before you use the extension harness with a trailer.
The manual does not specify a weight or load rating for the CURT 57010. However, it warns: do not exceed the product rating or tow vehicle lamp load rating, whichever is lower. Contact CURT Product Support at 877-287-8634 or visit curtmfg.com for the specific rating of your product.
Ensure the harness is routed so it will not pinch or bind when the steering wheel is turned. Use the cable ties provided to secure the harness along its path. After drilling the hole, smooth the edges with a metal file to prevent abrasion of the harness or connector.
