Installation
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. 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.
Route the 4-flat to the center of the vehicle. Secure the 4-flat to the center of the vehicle in a convenient,out of the way location or the rear hitch. Use the provided cable ties to secure any loose wires.
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.
Powered Tail Light Converter with Surface-Mount Technology
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.

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.by: Roderick05/10/2023
My order arrived yesterday, and it was on time and intact, but when I started installing the wiring system, C56406 I noticed the small parts shown in the layout, the 15 Amp fuse, the 2 butt connectors, and the eye crimp connector were not included. It's no big deal but I'm 40 miles from Town so it would be nice to know I needed these items to finish the installation. I have the connectors but no 15 Amp fuse.
by: Kenneth 06/11/2023
It is a complete add on towing light kit that was easy to install and it worked perfectly. The only somewhat difficult part of the install is running the power cable from front to back and that is only because of how low to the ground my car is. If I needed another kit I would buy the same kit from etrailer.

Developed a “short” somewhere causing the running lights to stay on constantly. Checked ground and wiring and still can’t trace it down.
Jenny N.

There could be more than one reason why the trailer lights are staying on constantly, starting with a corroded connector. What corrosion does is cause a short which can lead to the lights staying on, and when you unplug the connectors, they would, of course, turn off. So, start by checking there, and if you cannot clean the corrosion, you can replace the connectors on either the side of your vehicle or trailer. The other possibility is a short caused by damaged wiring on the trailer itself that is causing the power to remain, so you will want to check your wiring carefully looking for any damaged wires and repair or replace as needed with 10-gauge wire part # 10-1-1. I have added a link below to a help article on a troubleshooting guide for you to take a look at.

I bought this kit so I wouldn't need to cut my jeeps harness. It was a simple install by plugging into the taillight harness and has worked flawlessly.
by: Michael W08/30/2019
2019 Jeep Cherokee
Pretty easy to install. I would recommend, if you have to drop muffler to install your hitch, install your wiring BEFORE reattaching the muffler. Also the directions stated to fish the wires UP through the bumper to the tail light. My arm is not thin or long enough for this. I dropped a ratchet strap down through the bumper, hooked it to the wire and pulled it up. Super easy. The power wire I ran under the wheel wells behind the plastics. Same with the undercarriage. Removed some bolts for the plastics and tucked the wire. I mounted the connector to the hitch with a cheap zip tie bracket I also bought from this site.
by: Daniel 07/21/2023
Easy installation, only thing I would change about this product is I would add a few more zip ties for a nice clean install.

Hitch and T-Connector arrived in a few days. Fit was great and install was very easy. It is a very heavy-duty piece. The T-connector for the wiring makes it really easy to connect to brake lights. Plug and play.

Plenty of extra wire length. Easy to follow instructions.

Only thing I would suggest is including more butt connectors and zip ties in the kit. It's nickel and dime stuff and you can easily mess up a butt connector and have to go purchase another. Cost is minimal, and the time to go to a local store for extras is a pain. But overall, great product.
