Stop fighting with universal wiring kits and electrical tape. The CURT 56296 is a custom-fit, vehicle-side trailer wiring connector engineered to integrate directly with your vehicle's factory tail lamp harness. No wire splicing, no drilling, no cutting into your factory circuits -- just a clean, manufacturer-grade electrical connection between your tow vehicle and trailer lighting system.
CURT's custom-fit wiring connectors are built to match the specific plug configuration and wire layout of the OEM tail lamp harness on select vehicles. The 56296 uses a T-connector design that inserts inline between your vehicle's existing connectors, drawing trailer lighting power from the factory circuit without any permanent modification to the vehicle's wiring.
The result is a wiring solution that looks and performs like it came from the factory -- because it's designed around the factory harness, not around a one-size-fits-all approach. This makes it a favorite for RV towers, camper haulers, and anyone who needs a reliable, repeatable trailer hookup without compromising the tow vehicle's electrical system.
Plugs directly inline with the factory tail lamp harness. Zero cutting or splicing into OEM wiring required.
Delivers the industry-standard 4-way flat trailer plug: left turn/brake, right turn/brake, running lights, and ground.
Engineered to match specific vehicle harness connectors -- not a generic adapter. Ensures proper pin alignment and secure seating.
Connectors and wiring are rated for outdoor, under-vehicle exposure. Resists moisture, road grime, and vibration typical of towing use.
Unlike universal wiring kits that require you to identify individual wires, test circuits, and splice in new leads, CURT custom-fit connectors use a T-harness approach. The harness includes two female connectors that unplug from your vehicle's existing tail lamp sockets, plus a matching male connector that reconnects to the factory lamp. A pigtail then routes to a standard 4-flat trailer connector at the rear of the vehicle.
Because the harness is vehicle-specific, every connector is keyed to fit only the correct socket. You cannot accidentally plug it in backward or into the wrong lamp. This makes installation straightforward even for first-time DIYers -- typically 20 to 30 minutes with basic hand tools and no wiring experience required.
The output end of this harness terminates in a standard 4-way flat (4-flat) connector, the most common trailer wiring standard in North America. It supports:
The 4-flat connector is compatible with the vast majority of small trailers, boat trailers, utility trailers, cargo trailers, pop-up campers, and lightweight travel trailers. It does not support a dedicated brake controller circuit or 12V auxiliary power -- for those functions, a 5-flat or 7-way connector is required.
CURT part 56296 is a vehicle-specific connector, meaning it fits a defined list of makes and models. CURT custom wiring connectors in the 56xxx series are commonly matched to domestic and import vehicles including select Chevrolet, GMC, Ford, Toyota, Honda, Jeep, and Dodge platforms. Always verify fitment using CURT's online vehicle lookup or the application guide associated with this part number before ordering.
Installation requires no special tools beyond basic hand tools. The general process:
