  • CURT

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.

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights

  • Connects quickly and easily - no cutting or splicing of wires

  • 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 amps per circuit
    • Tail lights: 5 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 interior trim panel in your rear cargo area.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your 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.


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.

I am a returning customer of etrailer several times over. They truly have excellent service and support and I will be returning again in future for all my trailer hitch needs!!!

This Curt trailer light wiring harness fits my Kia Optima very nicely. Once the trunk interior trim panels are removed the installation is simple.

2015 Kia Optima

Received the hitch and wiring kit for my 2015 Kia one day sooner than promised. I watched the video installation and and no problems installing either of them. I have ordered from E trailer several times and have always been pleased with their products and service,. GOOD JOB E Trailer.

I was apprehensive about doing electrical modifications on my car but found installation to be incredibly easy thanks to the video etrailer.com posted online. I especially liked that I didn't have to do any wire splicing. Additionally shipping was very fast. I received my order one day before I expected it.

2013 Kia Optima

Great info provided by eTrailer folks on what would suit my needs.
Installed on a 2013 Kia Optima in one hour total.
Because Kia added panel access ports, I didn't even have to fully remove the trunk corner trim panels covering the light terminals.
Couldn't have been any easier to install.

2015 Kia Optima

  • Recommended Hitch and Trailer Wiring for 2014 Kia Optima Hybrid
    The Draw-Tite Class I hitch you referenced, part # 24965, would work well as long as the weight of the trailer plus its cargo was less than the 2000 lb capacity of the hitch. You'll also want to make sure that the weight of the trailer plus whatever's loaded on it doesn't exceed the towing capacity of the vehicle itself. I checked an online copy of the owner's manual for the Optima's towing capacity, but wasn't able to find any capacity listed, so you'll need to check with your Kia dealer. A...

  • Hitch for 2015 Kia Optima
    For you 2015 Kia Optima you would want the Curt Hitch part # C11025 like you referenced. For trailer wiring you would want the Curt Harness part # C56058. For a ball mount you would want part # C45521, pin and clip part # F-4, 2 inch ball part # A-82, 1-7/8 inch ball part # A-80.

  • Trailer Hitch and Wiring Recommendations for a 2013 Kia Optima LX
    Draw-Tite trailer hitch # 24965 is rated for 2,000 pound gross trailer weight and 200 pounds tongue weight. However, you will need to consult the vehicle owners manual to determine the capacity of the 2013 Kia Optima. Whichever is lower, the hitch or the vehicle, is the capacity you will need to go by. You will need the proper ball mount. For a 1-7/8 inch ball use # 19256 and for a 2 inch ball use # 19258. Different wiring harnesses have different capacities. Tow Ready harness # 118453...

  • Recommended Ball Mount for Curt Hitch On 2012 Kia Optima
    The Curt Trailer Hitch Receiver part # C11025 is an excellent option for a 2012 Kia Optima. If you will be towing, you must use the Curt Drawbar part # C45521 as this is what Curt recommends. They also do not offer any adjustable ball mounts for class I hitches so there's that as well. I have attached some other parts below you might need as well.

  • Trailer Wiring Harness for a 2013 Kia Optima SX
    For a 2013 Kia Optima SX you would have to use trailer wiring harness # 119179KIT. Curt states that harness # C56058 will not fit the SX models.

  • Can 2014 Kia Optima Taillights Be Operated Through Trailer Wiring Harness While Being Flat Towed
    The Curt # C56058 is designed for output only, you wouldn't be able to use it to operate the vehicle's taillights while the vehicle is being towed. You can either use a magnetic tow lamp like the # RM-2120 or a diode kit like # RM-154. The magnetic tow lamp would be the simplest option, it wouldn't require cutting and splicing into the existing vehicle wiring. The diode kit would require some cutting and splicing, but once the install is complete, it would be easy to use. I've linked...
