Adding trailer lighting doesn’t have to mean splicing wires or tracking down circuits. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs inline with the tail light wiring using factory-style connectors. It’s a true plug-and-play setup that keeps the vehicle wiring intact and gets you ready to tow quickly.
The harness connects right behind each tail light, keeping the install neat and out of sight. Once plugged in, the converter box tucks securely away and the 4-flat lead routes easily to your hitch area. The end result looks clean and professional, without any loose wires hanging below the bumper.
The 4-pole flat connector provides all of the basic trailer lighting functions—running lights, brake lights, and turn signals—so your trailer stays safe and visible on the road. It’s also compatible with standard 4-flat accessories and adapters when you need to connect to other wiring setups.
For vehicles without factory tow wiring, this harness includes an integrated converter that adapts the vehicle’s separate brake and turn signals into a combined signal for trailer lights. That means it delivers the proper output every time without needing extra relays or power wiring.
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light assemblies to access this harness.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
A tail light converter is built into this T-connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Works great after one year of towing my boat to the launch. Would highly recommend for the Jeep Liberty V6, towing 2,000 boat with ease

Still working fine after one year. I recommend applying bulb grease electrical lubrication to both trailer electrical connectors to keep moisture out of the connectors. keeps them from turning green with corrosion

Great! I just finished moving and needed to rent a trailer several times. The wiring harness is still working perfectly and the insulation intact.

One year later, everything is working excellent. As a matter of fact, the factory wiring harness was burning out bulbs about as quick as I could change them. Since I have installed the harness from etrailer, I have not had to replace one bulb in the year Ive had it installed. It dealt with a U-Haul 4 pin, twin axle trailer for over 600 miles like a champ! Not a glitch. Still goin strong. Like I said a year ago, awesome product! Thank you etrailer.

Highly recommend this harness! Since the install on the 2005 liberty Ive installed another harness on my 2007 Commander. Again, very easy to install.

Thanks for checking. I only pull that vehicle a few times a year. The last time was last Fall so I cant really tell you if it is still fine or not.

Ive used this connector twice in the past year, hooked right up to a rented Uhaul trailer no problem , all lights still perform and function as they should. Very happy to have the option to tow, since I dont own a truck. Etrailers has made it possible. By the way my Jeep was hit from the back smashing the back swing door in the etrailer harness was uneffected,didnt fall off from its mounting position wow Im impressed . thanks for a great product
