CURT 4-Way Flat Trailer Wiring Harness for 2021+ Ford Bronco with LED Tail Lights — Plug-and-Play 4-Pin, Converter & Dust Cover

The CURT 56468 is a vehicle-specific, plug-and-play 4-way flat trailer wiring harness engineered to add OEM-style trailer lighting to select 2021+ Ford Bronco models with LED tail lights.

If your Bronco didn’t come prewired for towing, this custom CURT harness supplies a factory-friendly solution that avoids cutting or splicing. It uses vehicle-specific connectors to mate with the Bronco’s taillight sockets, gives you a standard 4-pin flat output for tail, brake and turn signals, includes an integrated tail light converter and protects the plug with a rubber dust cover when not in use. Built with SMT circuitry and purpose-made components, the 56468 aims to deliver a tidy, reliable electrical link between your vehicle and trailer.

How does this harness install on my Bronco?

Installation is designed to be straightforward with no wire cutting required. The harness plugs into factory-style connectors behind the tail lamps and routes to the hitch area so the 4-way flat socket is vehicle-side accessible.

• Vehicle-side T-connector uses OEM-compatible plugs that insert into the Bronco’s taillight harnesses.
• No splicing or soldering — preserves factory wiring and simplifies removal.
• Includes mounting points and routing length suitable for common hitch locations.

Will this work with my Ford Bronco’s LED tail lights?

This CURT harness is made specifically for select 2021 and newer Bronco models equipped with LED tail lights; it incorporates a converter designed to ensure correct signal behavior when interfacing with LEDs. Always confirm the application fitment for your exact year and trim before ordering.

• Integrated tail light converter balances LED and trailer lamp signals for compatibility.
• Designed for models noted in CURT's fit guide — verify your VIN or model year range.
• Vehicle battery connection required to support stable power for trailer lighting.

What electrical features and protections are built in?

CURT engineered the 56468 with SMT circuitry and quality connectors to reduce heat, improve signal integrity and increase longevity under towing conditions. A rubber dust cover is included to guard the 4-way socket from contaminants when not in use.

• Surface-mount technology (SMT) circuitry for consistent output and thermal management.
• Durable molded connectors and strain reliefs to resist vibration and outdoor exposure.
• Included dust cover protects contacts from dirt and moisture between uses.

What types of trailers can I tow with this 4-way connector?

The standard 4-way flat delivers tail lights, turn signals and brake light circuits suitable for small to medium trailers that use a basic lighting harness. It’s ideal for utility trailers, small boat trailers, cargo carriers and other non-electric-brake setups.

• Supports tail, stop and left/right turn signals for conventional trailer lighting.
• Works with trailers using a 4-way flat plug; not intended for heavy-duty electric brake control circuits.
• Pairs with common trailer accessories (cargo carriers, small boats, utility trailers).

Who is this for? The CURT 56468 suits Ford Bronco owners who want a clean, factory-like trailer wiring solution without modifying factory harnesses. It’s aimed at drivers who tow small-to-medium trailers occasionally and want a dependable, removable connector that integrates with LED-equipped Bronco models. If you need a vehicle-side, plug-and-play 4-way flat harness with a built-in converter and protection from the elements, this unit is a practical, OEM-friendly option—just verify compatibility with your Bronco year and LED tail lamp equipment before purchase.
