Founded in 1931 to supply electrical connection products to the United States military, Bargman is now the RV industry's most widely recognised lighting brand. The line covers tail light assemblies, clearance and marker lamps, licence plate lights, wiring harnesses, plugs, sockets and over-moulded cordsets for light-duty trailers, recreational vehicles and commercial trucks.
Bargman was founded in 1931 to provide electrical connection products for the United States military, and it carried that background into civilian markets after the war. The brand has since become the reference name in light-duty trailer and recreational vehicle lighting, and its products are equally familiar to commercial truck and trailer manufacturers and their aftermarkets. It is part of the Horizon Global towing family alongside Reese, Draw-Tite, Fulton, Bulldog, Tekonsha and Wesbar.
Complete tail light assemblies are the products most owners recognise. Bargman lamps are fitted as original equipment across a large share of the RV industry, which means a replacement usually drops straight into the existing cut-out and wiring rather than requiring a redesign of the rear panel. The wider trailer light range covers stop, turn, tail, reverse and interior functions in both incandescent and LED technology, and clearance and marker lamps handle the outline lighting that longer and wider units require by law.
The electrical side of the business is where the manufacturing capability shows. In-house over-moulding and custom mould capability, combined with design and engineering, lets the brand build harnesses and connectors to specification rather than assembling from stock parts. Bargman specialises in assemblies with multiple connections, varying wire lengths and mixed technologies, which is exactly what a modern RV needs when a single harness has to serve lighting, brakes, charge lines and accessory circuits.
That capability supports a full range of plugs and sockets and pre-made cordsets, including the seven-way connectors used for trailers with electric brakes and battery charging. For RV manufacturers, trailer builders and owners alike, the appeal is the same: connections that seal properly, resist corrosion and keep passing signal after years outdoors.

The Bargman Fifth Wheel Harness, 7-Way BM54700-003 (Part #BM54700-003) fits 1999-2024 Chevrolet Silverado 1500 models. The 2025 model year is the last year covered by this part number. For newer models, check for an updated version.
The Bargman Fifth Wheel Harness, 7-Way BM54700-003 (Part #BM54700-003) Drilling is required for installation. Basic hand tools are typically all you need.
The Trailer Tow Harness is an adapter that connects between your vehicle's factory 7-way harness and your trailer's electrical connector. It enables power delivery to trailer lights and functions. The harness mounts to the vehicle frame and interfaces with the factory 7-way connector located on or near the rear bumper.
Yes, the Trailer Tow Harness is compatible with Dodge vehicles. The manual notes that the Dodge version connector is rectangular, distinguishing it from other vehicle types. Your vehicle must have a 7-way factory harness on or near the rear bumper for this harness to function.
No. The Trailer Tow Harness is designed to install between your vehicle's existing factory 7-way harness and the trailer connector. If your vehicle does not have a factory 7-way harness on or near the rear bumper, this product will not function.
You will need: a drill with 3/32" and 1/4" drill bits, a 2" hole saw, a 5/16" socket, and a center punch. A panel removal tool is also listed. These tools are required to drill mounting holes, create the main mounting hole, mark hole locations, and remove trim panels if necessary.
The harness includes four self-tapping screws for mounting the 7-way connector to the vehicle surface, and a spacer for use between the 7-way plug and truck bed if the 90-degree bend corner is too close to the outside wall of the truck bed. Rust-proof coating is not provided but is recommended for drilled areas.
The mounting point is typically on the driver's side of the vehicle, between the rear cab post and in front of the wheel well area. You must verify there is adequate clearance at your chosen location before drilling. The harness mounts to the vehicle frame using a 2" hole.
Yes. Installation requires drilling a 1/4" pilot hole, then a 2" hole for the main mounting location, and four 3/32" holes for the self-tapping screws that secure the 7-way connector. Before drilling, you must verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into exposed surfaces.
If your vehicle has a bedliner, you have two options: notch the bedliner to accommodate the harness, or use a longer set of screws (not provided) and mount directly into the bedliner and body panel. The manual does not provide specific guidance on which option is preferable for your vehicle.
Yes. The manual recommends using rust-proof coating in all drilled areas to prevent future rusting. This coating is not provided with the harness and must be purchased separately.
Route the OE wire connectors carefully through the 2" hole, taking care not to scrape or damage the wires against the sharp edges of the sheet metal. Use the 7-way end as a guide to mark the mounting hole locations with a center punch before drilling the four 3/32" holes.
Locate the vehicle's 7-way factory harness on or near the rear bumper. Separate the factory connector carefully, being careful not to break the locking tabs. Ensure all connector surfaces are clean and free of dirt. Install the Trailer Tow Harness between the mating plugs. All connections must be complete for the harness to function properly.
Use the spacer provided between the 7-way plug and the truck bed if the 90-degree bend corner is too close to the outside wall of the truck bed. This prevents the connector from being forced against the bed wall.
Route the wire carefully to avoid hot pipes, heat shields, the fuel tank, or any other points that may pinch or break the wire. Secure all loose wiring after installation to prevent movement and potential damage.
On some vehicles, you may need to add a fuse or relay (not provided) to complete all functions going to the 7-way connector. Consult your vehicle's owner's manual for the specific locations and part numbers required for your vehicle.
Test and verify the installation with a test light or by connecting an actual trailer once installed. All connections must be complete for the Trailer Tow Harness to function properly. If any function is not working, check that all connections are fully seated and that any required fuses or relays have been installed per your vehicle's owner's manual.
Wear safety glasses throughout the installation. Before drilling any hole, verify what is behind the surface to avoid damage to the vehicle or personal injury. Do not drill into exposed surfaces. Verify mounting location and wire lengths before making final cuts. Handle the factory connector carefully to avoid breaking the locking tabs.
The harness fits vehicles with a factory 7-way connector on or near the rear bumper. Dodge vehicles are compatible (rectangular connector). Consult your vehicle's owner's manual or contact the manufacturer to confirm your specific vehicle model is supported.
You need a drill with 3/32" and 1/4" bits, a 2" hole saw, a 5/16" socket, and a center punch. A panel removal tool is also required.
Either notch the bedliner or use longer screws (not provided) to mount directly into the bedliner and body panel. The manual does not specify which method is preferred.
Some vehicles require an additional fuse or relay (not provided) to complete all 7-way functions. Check your vehicle's owner's manual for locations and specifications.
Use a test light or connect an actual trailer to verify all functions are working. All connections must be fully seated and complete for proper operation.
Wear safety glasses. Always verify what is behind any surface before drilling to avoid damage or injury. Do not drill into exposed surfaces. Handle the factory connector carefully to avoid breaking the locking tabs.
