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.

Benefits of CURT surface mount technology (SMT)

CURT Trailer Wiring Circuitry

CURT Trailer Wiring Lights

CURT Trailer Wiring Harness 7-Way RV Blade

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

Stress is the last thing you should feel when towing a trailer -- whether you're hauling your RV to that favorite camping destination, your ATVs up to the hunting grounds or your fishing boat to the new hidden hotspot. At CURT, we think your towing equipment should add to the enjoyment of your experience, not detract from it. CURT custom wiring connectors are the easiest way to outfit your vehicle with a CURT trailer wiring connection. They are built with some of the most advanced technology in the industry, and each one is custom-fitted to work with a specific make and model. Some automotive manufacturers install a special socket on the vehicle to be used for vehicle-to-trailer wiring. Though this special socket is not equipped on every vehicle, a CURT custom wiring connector (also called a T-connector) utilizes the socket for simple, stress-free installation. Rather than requiring you to cut, splice and solder into your vehicle's wiring system, the custom wiring connector uses a single OEM-compatible plug and instantly provides a standard vehicle-to-trailer wiring connection, typically in the form a 4-way flat. All CURT custom wiring connectors are made vehicle-specific for the easiest possible installation and the best fit. This particular connector provides a 4-way flat socket while retaining use of the existing OEM socket. It is designed to be a custom wiring option for a variety of vehicles (see application info to verify fitment with your vehicle). It comes with a dust cover to keep the connector socket clean when not in use.

    Took a little work, but I vastly improved the cable layout
    4 Stars
    Took a little work, but I vastly improved the cable layout
    So first thing first, between the two large connectors is literally only 3-4 inches of very stuff wire, makes it impossible to do wire management. After the spilt is 4 ft of wire to the 4 pin harness, I'm using this to hook up a light bar on my truck which has its own 4 ft of cord so, I capped the length at 2 ft ordered 2ft of 7 pin trailer wire and went to town.The middle wire is the reverse if you needed it for a light bar, they give you at least 6ft of that with most light bars, so no need to make it more than 6 inches or so. They do not follow the standard for write coloring charts so reverse, 12v, ground and brake controller are all white wires, it can get confusing, I used post it note tags (just cut the sticky part of a post it and use that.)Ended up getting two of these the first one the reverse wire isn't secure in the harness and keeps losing connection, but I'd already cut into that wire. So the second one I immediately hot glued all the wires into the harnesses as soon as I got them, just took of the grey part hot glued and replaced the grey part, they don't move now. All that is left now is to get wire loom, at least 3/4 inch.To be honest, I think Curt should make one exactly like this, specifically for people hooking up light bars, they make custom wiring harnesses and it is a rather common thing people are looking to get set up. Added a final product, as you can see, it is a much better setup, the small l.pplug goes on the bumper the rest can be managed and organized out of the way
