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 trunk floor coverings and the rear scuff panel 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 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.


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.


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.

This company is amazing!!! I love them!! Very helpful, very professional. I need this for a trip I am making and they had it delivered very quickly, in 2 days. The wires were very easy to install and are very good durable cables, not that cheap over price cables other places sell.
If your debating on buying them or not as I was, just do it. You won't regret it, I didn't!

See what our Experts say about this CURT Custom Fit Vehicle Wiring

  • Could Trailer Wiring for 2013 Kia Optima be Used for Powering Bumper Lights on Vehicle
    If you installed the Curt harness part # C56314 on your 2013 Kia Optima you would be able to use it as a way to splice in additional taillights if needed. The white wire would get grounded. The brown would go for the running lights, the yellow for left turn/stop, and the green for right turn/stop. Essentially what you would be doing would be just like powering a trailers taillights so this harness would work just fine. To isolate out the stop light you would need the converter part # 118158.

  • 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.

  • Is The Curt C56314 What I Need To Pull A Utility Trailer With A 2015 Kia Optima SX
    Hello Gerard. The Curt T-Connector Vehicle Wiring Harness # C56314 is exactly what you will need to tow a utility trailer with your 2015 Kia Optima SX. The 4-flat connector is very standard for utility trailers. Any trailer that does not have its own brakes will use the 4-flat.

  • Trailer Wiring Harness that Fits 2015 Kia Optima SX
    Hey Jerry, the Tekonsha trailer wiring harness part # 118453 does fit your 2015 Kia Optima but it currently is on a pretty long back order so instead you would want the part # C56314.

  • Trailer Hitch and Towing Equipment for 2011 Kia Optima Hybrid
    According to Curt, their Class I hitch, part # C11025 fits all models of the 2011 Kia Optima, including the hybrid. If you'll be towing with the hitch, you'll also need a trailer wiring harness, a ball mount and a trailer ball. For a wiring harness, use # C56314 and for a ball mount, use # C45521. For a 1-7/8 inch trailer ball, use # A-80 or # A-82 for a 2 inch ball. I've linked you to install videos for the hitch and the wiring harness.

  • Trailer Wiring Harness Recommendation for 2013 KIA Optima SX
    As long as your 2013 KIA Optima isn't the Hybrid model, the Curt # C56314 would be compatible with the LED taillights on your vehicle. This is what's known as a powered taillight converter, which draws the power from the taillights directly from the vehicle battery, rather than drawing it through the taillight circuits. The isolates the electrical system of the Optima from that of the trailer, which will protect the vehicle's wiring from being damaged by any short circuits that might occur...

    Yes, it will! The Curt Hitch item # C11402 is confirmed to fit all models of the 2020 KIA Optima including the SX which has dual exhaust. This hitch is custom fit and bolts to your Kia with included hardware. The Curt Hitch item # C11402 is a class I hitch with a 1-1/4" receiver. It has a 2,000 lbs towing capacity and a 200 lbs maximum tongue weight. I have linked an installation video below to help you get it set up. If you are planning on towing you will also need a wiring harness...
