Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector

  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 3.0 amps per circuit
    • Tail lights: 5.0 amps per circuit
  • Limited 1-year warranty


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 installation is complete, the 4-way connector will be stowed in an out of the way location inside the trunk.


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.


Tail Light Converter with Surface-Mount Technology

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.


Curt SMT Circuit Boards

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.

Hitch and wiring harness for trailer connection are both quality constructed. Installation videos are well done and easy to follow for quick painless installation. And the price paid was very affordable, online ordering painless.

Went in easy enough. Looks like the 4 prong plug could be a little longer. I used some adhesive zip tie holders i had to clean up the wiring a little more. Just zip ties to hold the wires are not enough.

Good instructions, installation was straight forward, not too complicated. The custom plugs made it very easy.

Both wiring harness that I purchased over the last 4 yearsone to a 2014 Tucson & one for a 2016 Accent continue to perform excellently with no issues. Maintenance has consisted of an inspection and sometimes application of WD-40 to minimize the tendency for corrosion of the contact pins. I am very satisfied with this product.

  • How to Install a 4-Way Wiring Harness in a 2016 Hyundai Accent Sedan
    Hey Matt. The Curt T-Connector Vehicle Wiring Harness item # C56149 does indeed come with installation instructions. I have linked them below as well. The wiring harnesses you are looking for are located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. Right behind the tail lights essentially. As far as a ground goes. You can look around for a bolt and clean off the paint around it and attach it to that. Or you can drill a hole, clean the paint...

  • Which Curt Trailer Wiring Harness Fits 2013 Hyundai Accent Hatchback
    The correct Curt trailer wiring harness for your 2013 Hyundai Accent Hatchback is the part # C56254 and not the # C56049 as it only fits Sedans. I put a note in your order notes that you are going to need to cancel and reorder the correct kit.

  • Troubleshooting Inconsistent Trailer Stop/Turn Lights with Curt Wiring on a 2013 Hyundai Accent
    Thank you for all of the details about troubleshooting the Curt T-Connector # C56254 on your 2013 Hyundai Accent. Since you said the ground is secured to a clean, bare-metal surface and all of your other wiring looks to be in order it is very possible that the issue is actually on your trailer, but I recommend using a circuit tester # PTW2979 to see whether the power is getting to your 4-Way connector or not. If the tester works fine then the problem is on your trailer, but if it isn't...

  • What Size Ball Mount Comes with Hidden Hitch Trailer Hitch for 2016 Hyundai Accent Hatchback
    The ball mount that comes with Hidden Hitch trailer hitch # 60301 (no longer available) for your 2016 Hyundai Accent hatchback is # 3592. On a Class I trailer hitch like this you have to use the ball mount specified by the hitch manufacturer or it voids the hitch warranty. The ball mount must be used in the rise position only. For a 1-7/8 inch ball use # 19256 and for a 2 inch ball use # 19258. And for trailer wiring use # C56254. Please note that the vehicle owner's manual states that...

  • Curt T-Connector 4-Pole Trailer Wiring Harness for 2014 Hyundai Accent Sedan
    The correct Curt T-Connector trailer wiring harness for your 2014 Hyundai Accent 4-door sedan is part # C56149. The part you referenced, # C56254, is a correct fit for the Hatchback version, but not for the sedan. This harness offers simple plug-in installation with no cutting or splicing of wires. The install instructions are linked for you. It is a good idea to apply dielectric grease # 11755 to the connectors before installation as this will help prevent entry of contaminants and moisture...

  • Trailer Turn Signals Do Not Blink In Tandem with the Vehicle Turn Signals
    Usually when towing a trailer, the turn signals will blink together with the tow vehicle and not alternate like what you are describing. So, I would say what you are experiencing is not normal. It is hard to say if it is a problem with the trailer wiring harness # C56254 or something that went wrong during the installation process. I would make sure that all of the grounds are attached to clean and corrosion free bare metal surfaces. I also recommend checking the trailer side connector...
