Designed to mate with the OEM taillight sockets on select Honda Civics (non-hybrid), Fit 5-door, Accords without LED taillights, Mazda 3, Mazda CX-5 and Mitsubishi Galant 2.4L single-exhaust sedans, this harness provides brake, tail and turn signal circuits in one compact assembly. The kit includes the wiring and a dust cover so the connector stays clean when not in use, and the circuitry is built to industry standards for reliable towing performance.

How simple is installation with the CURT 56011?

Installation is straightforward because this harness uses vehicle-specific plugs that mate directly with the factory taillight connectors. There’s no need for cutting, splicing or soldering, so you can get a working trailer connector in minutes using common hand tools.

What trailer functions does this 4-way flat provide?

The 4-way flat output carries the basic trailer lighting circuits: left and right turn signals, brake lights, and running/tail lights. It’s the standard connector for small trailers, utility trailers, and many boat trailers, giving you the essential lighting signals needed for legal and safe towing.

• Left and right turn signal feed
• Brake light circuit pass-through
• Tail/running light output

Will this harness work with my vehicle and LED taillights?

CURT 56011 is built for specific vehicle models and years—confirm compatibility with the product application list before purchase. This particular harness is intended for vehicles without LED taillight assemblies; LED systems may need a different adapter or a harness with an integrated LED-compatible converter.

• Designed for select Honda, Mazda, and Mitsubishi models (verify fitment)
• Not for vehicles equipped with LED taillights unless specified
• Includes a converter to match vehicle-to-trailer signal requirements
• SMT circuitry supports stable signal transfer and durability

How durable and dependable is the wiring and connector?

The CURT harness uses surface-mount technology (SMT) circuitry and robust connectors to resist vibration and corrosion common in towing applications. The built-in dust cover and quality materials help maintain a secure electrical connection over time, reducing troubleshooting on the road.

• SMT circuitry for consistent signal performance
• Weather-resistant materials and molded connectors
• Protective dust cap keeps contacts clean when idle
• Designed for repeated connect/disconnect cycles

Who is this for: The CURT 56011 is ideal for drivers of the specified Honda, Mazda and Mitsubishi models who need a no-fuss way to add towing lights for a small trailer, boat or cargo carrier. It suits DIY installers, owners who prefer to keep factory wiring intact, and anyone seeking a compact, OEM-compatible 4-way flat connector that installs quickly and performs reliably for routine towing tasks.
