Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area. You will have to remove the taillights to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.
Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your rear cargo area.
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. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
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.

This was part of my new hitch installation and made the installation very easy. I would not have enjoyed the installation without this wiring kit.
A great company with great employees that know how to get the job done. Will not order my hitches anywhere else.
Thank you
I ordered the wrong kit, and etrailer was very helpful in sending me a return label and the correct kit. Thank you.
Difficult installation as impossible to fish connectors through rear lights, had to cut wires, fish only wire, and re-attach. On hybrid batter located in interior in back of car. Compartment is sealed so need to drill hole through metal as best way to attach power
Good fit, good installation video.
Wiring kit for my 2022 Pacifica came with everything needed for installation. It is quite difficult to pull the harness up to the tail lights with a fish tape as the pathway is already full of the factory wiring. With a bit of patience and a few test fits to get all the connectors to fit behind the lights I was successful. It was easy to fish the power wire between the floor and belly pan to get it to the battery.
I have used your products before and I would certainly use them again!
Great product easy to install. All good
Easy to install with a little patience and a LIFT.
Sent me the wrong part to start with but their manager made it right
