CURT Custom Trailer Wiring

Wherever your work or play takes you

CURT offers custom trailer hitches, electrical products and a complete line of towing accessories to get you there with confidence and enjoy every mile of the journey.

4 Pin Trailer Wiring Harness Connector

CURT Custom Vehicle-Trailer Wiring Harness

Custom fit. Plug-and-play. Reliable power.

A CURT custom trailer wiring harness is the easiest way to equip your vehicle with the proper electrical connection for towing a trailer. Our custom wiring offers simple, plug-and-play convenience with no cutting or splicing required, and provides a reliable connection for powering your trailer lights.

Best of all, each CURT custom trailer wiring harness is made vehicle-specific for a unique make and model. This makes installation hassle-free and ensures optimal performance with your vehicle.

Key features of CURT trailer wiring

  • Simple, plug-and-play installation
  • Constructed with SMT circuitry
  • Provides a standard trailer wiring output, usually 4-way or 5-way flat
  • Dust cover included to keep connector clean when not in use

Two types of trailer wiring

CURT offers two types of custom trailer wiring: custom wiring harnesses and custom wiring connectors. Both are made for specific vehicles, and both require zero cutting or splicing.

Custom trailer wiring harnesses

A custom trailer wiring harness (also known as a ‘T-connector’) is designed to ‘T’ into your vehicle’s taillight assembly. This simply requires access to the taillight wiring.

Custom trailer wiring connectors

A custom wiring connector uses a single plug to plug into a designated OEM socket on the vehicle. Not all vehicles are equipped with this socket, but it does make installing very easy.

Both vehicle-specific

Each custom trailer wiring harness and connector is made for a specific make and model, featuring the necessary components to provide a standard trailer wiring output.

Selecting custom wiring

Whatever your lifestyle, choosing the right CURT custom trailer wiring harness for your vehicle is easy. Simply use your vehicle's year, make, model and style.

Minimum heat generation

The high-quality components used in our custom trailer wiring create very little resistance to reduce heat, limit voltage drop and extend the life of the circuits.

Optimum light intensity

SMT is manufactured with automated processes for maximum consistency and the highly efficient circuitry promotes optimum intensity and life for the trailer light.

Durable performance

Surface mount technology is able to better withstand shaking and vibrations, conditions that are common while towing, compared to traditional through-hole-mount tech.

Product Description

If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Jeep Wrangler JK (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.
