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.
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
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.
Benefits of CURT surface mount technology (SMT)
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.
