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 5-way flat socket while retaining use of the existing OEM 7-way. 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.

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

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.

Great item, great price

Reviewed in the United States on October 29, 2016

Verified Purchase

Great item, great price. Tucks up nicely under my truck hiding all the extra wiring from my installed lights. If you are looking to add REVERSE light functionality from your TAILGATE LED light bar or something on a GM truck or pre-wired truck or vehicle then this is plug and play. Most people buy the 4-way (4-pole) version. This however is the one you need if you want be able to use REVERSE lights in a plug and play fashion such as for those tailgate light bars. Then, just add a bullet connector to your wiring from the led tailgate light bar and plug it in. Works great as long as your vehicle has the standard 7-way wiring like most GM trucks have from the factory.

Has reverse pin, great for tapping into for added reverse lights.

Reviewed in the United States on November 27, 2019

Verified Purchase

Used on a 2014 Sierra 1500 with stock tow package.
So what I like about this is the fact that it has the 5th pin for reverse lights. I used this to Plug N Play into the vehicle wiring so I could add some reverse LED lights in the bumper without having to tap into the stock wiring.

Keeps Factory Harness untouched when doing mods!

Got this to wire in some step lights on my 2018 Silverado and also rear reverse LED lights that mount under the bumper. This goes between the factory wiring so you wire into this and don't touch factory wire with cruddy T taps and the like. THe fifth wire (blue) on this from the reverse lights. Perfect for someone wanting to add one of those under the tailgate light bars or do what I did and not have to touch the fatory harness!

I bought this so I could install an LED tailgate light bar with reverse lights, and not cut into my factory wiring harness.

It installs easily, I had other work to do on my truck so I removed my bumper giving even more access. Worth the money to keep an uncut wiring harness

6 Pin plug?

Reviewed in the United States on May 6, 2018

Verified Purchase

I bought this so as not to have to splice a 4 pin trailer plug on my Silverado. The installation was easy but upon testing nothing worked; not the 7 pin nor the 4 pin. Upon removal and inspection the neutral pin is nothing but a stub that cannot make an electrical connection. Amazon is sending a replacement that I hope does not have this defect...will inspect prior to installation. I will update when the new one arrives.
I received the replacement and everything worked perfectly. The three star rating reflects the two extra times I had to crawl under my truck due to the defective initial order.

Works great and as expected. Fast deliver as always. Used to connect my tailgate light bar behind the bumper for a nice clean install. Well worth the money and saved me from wiring into my factory harness on my brand new truck. Would recommend !!

If you need another plug or are adding a light bar to your truck this is the only way to go. Effortlessly plugs into your current harness. Takes longer to crawl under the truck than it does to install it. Fantastic product!
