CURT 4-Way Flat Trailer Wiring Harness for Select Bronco — Vehicle-Side Plug-and-Play, No Cutting

The CURT 56471 is a vehicle-side, plug-and-play 4-way flat trailer wiring harness engineered to give select Ford Bronco models a factory-style trailer connector without cutting or splicing.

If your Bronco didn’t come pre-wired for towing, this custom T-connector from CURT restores full trailer lighting function quickly and cleanly. The kit uses vehicle-specific OEM-compatible plugs that mate with the Bronco’s taillight assemblies and provides a standard 4-way flat socket to power tail lights, brake lights and turn signals on a trailer. It includes a dust cover and the required electronics so you avoid permanent changes to factory wiring.

How does installation work and how long will it take?

Installation is designed to be straightforward: the harness uses the vehicle’s existing taillight connectors so there’s no cutting, splicing, or soldering required. Typical install time is short for anyone comfortable with basic vehicle access—often under an hour for a DIYer with simple tools.

• Plugs into taillight assembly using OEM-style connectors
• No wire cutting, taping, or soldering needed
• Includes all wiring and hardware for a complete 4-way connection
• Plug-and-play fitment for compatible Bronco model years (verify application)

Will this harness power my trailer’s lights and signals reliably?

Yes — the CURT 56471 provides a full 4-way flat output that carries tail, stop and turn signals to a trailer. It incorporates a tail light converter and SMT circuitry to ensure stable electrical performance and to protect vehicle and trailer electronics from common wiring mismatches.

• 4-way flat output for tail, brake, and turn lights
• Built-in tail light converter for compatibility with trailer wiring
• SMT (surface-mount) circuitry for improved durability and reliability
• Dust cover included to protect connector when not in use

Is this harness compatible with my Bronco and what should I check first?

This harness is vehicle-specific and compatible only with select Ford Bronco model years and configurations that match CURT’s application listing. Before purchasing, confirm your Bronco’s year and whether it uses LED taillights; this product is intended for Bronco models without LED rear lights.

• Check product application for compatible Bronco years and trims
• Not intended for vehicles with LED taillight systems
• Verify OEM connector type on your vehicle before buying
• Manufacturer provides fitment details to prevent mismatches

What durable features protect the harness from road use?

CURT designed the 56471 with long-term road reliability in mind: rugged connectors, dust protection and advanced SMT circuitry resist vibration and the elements. Those construction choices help maintain a consistent electrical connection trip after trip.

• Durable automotive-grade connectors for secure mating
• Dust cover keeps contacts clean when unused
• SMT circuitry increases resistance to shock and moisture
• Made to integrate with vehicle without altering factory wiring

Who is this for? The CURT 56471 is aimed at Bronco owners who need a reliable, non-invasive trailer wiring solution: do-it-yourselfers who prefer plug-and-play installs, vehicle owners who want to avoid permanent wiring changes, and anyone towing small trailers, utility loads, or recreational gear that uses a standard 4-way flat connector. If you require compatibility with LED taillights or need a multi-function braking system, consult CURT’s fitment guide or consider a different model tailored to those needs.
