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.
Product description
If you are replacing a broken coupler on your trailer or installing a new one on a trailer you are building, CURT has dependable couplers you can trust to keep your tow load latched on tight. Selecting the right trailer hitch, ball mount and trailer ball to manage the weight of your trailer is not the only important aspect of towing; you also need a trailer that can stand up to the road ahead. That means equipping it with a coupler that is built to go the distance. Providing the highest weight capacity and the most flexibility in coupler design, CURT adjustable channel couplers are a unique option for your trailer. This type of coupler does not bolt onto a trailer's frame the same way that a standard coupler does. It uses a pair of bolts to mount onto an adjustable eye channel to allow for easy height adjustment. The two attachment bolts also provide greater stability and less rattle. This CURT adjustable channel coupler features a cast design with a simple latch. It comes with a durable gloss black powder coat finish for corrosion resistance and has a gross trailer weight capacity of 14,000 lbs. and a tongue weight capacity of 2,100 lbs. It is designed to fit a 2-5/16" diameter trailer ball. All CURT couplers include a limited lifetime warranty and feature a lockable latch to give you peace of mind.
