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

Installation of CURT custom vehicle trailer wiring

CURT Trailer Wiring Connector Custom Vehicle Wiring

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.

CURT Vehicle Trailer Wiring Installation

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.

CURT Custom Trailer Wiring Installation Auto

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.

CURT Vehicle Trailer Wiring Connector Plug In

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.

CURT Towing Electrical Trailer Wiring Gooseneck Farm Truck

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.

Benefits of CURT surface mount technology (SMT)

CURT Trailer Wiring Circuitry

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.

CURT Trailer Wiring Lights

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.

CURT Trailer Wiring Harness 7-Way RV Blade

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

With any towing setup, there is always the need for a few additional items. Though your trailer hitch and ball mount may be tough enough to haul that heavy load, they cannot properly tow without a few supporting players. Towing accessories are a practical addition to your rig that add the finishing touches and take your towing experience to a whole new level. With the right accessories, the difference is a little like cruising the Grand Canyon in a deluxe RV as opposed to camping out in grandma's backyard. For protecting your trailer ball when not in use, the CURT rubber trailer ball cover is a perfect fit. This cover is designed to fit a 1-7/8" or 2" diameter trailer ball (trailer ball and ball mount not included). You never know what obstacles the road before you might bring. The key to overcoming them is to be prepared. From proper safety precautions to quality hitch maintenance, you can count on CURT to have the products you need to come prepared and always Bring It.
