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 light housing in your trunk.


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

An easy enough install, but there is nowhere to store the cables, except to use the loop-cover to attach the wires to the loop on the side of the hitch. Within 5 months of ownership, two of the wires were severed, having never been used. After 9 months, the remaining two wires also broke off, and I lost the connector without ever getting a chance to use the product. A real shame, and recommend some kind of hear-resistant cover on the exposed wires by the hitch.

It is a shame that the 4 flat connector broke off. I do have a few fixes that I can recommend if the harness is still installed. You can replace the connector using part # HM48190 which will also give you LED test lights to show that the harness is working. Then to keep the harness in place using a bracket like part # C58001 will keep the 4 flat next to the hitch.

The wiring was pretty straight forward and supplied everything you need to get the job done.

My trailer wiring harness was correct and it also arrived earlier than expected.

  • Can I Tow a Trailer with my 2017 Kia Forte EX
    We do have the equipment to tow with your 2017 Kia Forte, which is primarily due to consumer demand rather than hard to find towing information. You are also correct that per the owner's manual (page 5-91) it states that Kia does not recommend using your vehicle for trailer towing. I can't recommend towing with this vehicle since the manufacturer says not to and we can't provide a towing vehicle weight capacity. I can provide the weight capacity of the # C11368 which is 200 pounds maximum...

  • Can 2017 Kia Forte Sedan be Used to Tow 300 lbs - 500 lbs
    If you are planning on towing 300 - 500 lbs then we do have the equipment for your 2017 Kia Forte but please note that in the online version of the owner's manual (page 5-91) it states that Kia does not recommend using your vehicle for trailer towing. So the decision to tow will be entirely up to you and you need to check all of the weight ratings but it might be worth looking into a different vehicle if you plan on towing often. With that being said, I recommend using the Curt Trailer...

  • Recommended Trailer Hitch Receiver for 2016 Kia Forte EX Sedan with Chrome Exhaust Tip
    A factory exhaust tip is taken into account when a hitch receiver is designed. So the Curt # C11368 will fit your 2016 Kia Forte EX Sedan as long as the exhaust is from the factory. You should know that using the Curt Class I hitch receiver will require the use of a support strap # 18050 for any non-trailer loads like a bike rack. You can use the Draw-Tite Sportframe # 24903 instead which doesn't require the strap. If you're going to be towing with your Kia you can use # 3593 for a ball...

  • Can A 2015 Kia Forte Pull a Jet Ski
    The Curt Trailer Hitch Receiver part # C11368 has a 2,000 lb weight capacity therefore so long as the weight of the jet ski and trailer do not exceed this then you will be fine. However, the issue is that Kia does not recommend towing with your 2015 Kia Forte so that will be up to you to decide whether or not you abide by this recommendation. In order to complete your towing setup you will need the following: Curt T-Connector Vehicle Wiring Harness part # C53KR (Sedan Only) Curt Class...

  • What is the Correct Curt T-Connector Vehicle Wiring Harness for a 2005 Pontiac Vibe
    The correct Curt T-Connector Vehicle Wiring Harness for a 2005 Pontiac Vibe is part # 55057, not part # C53KR which is for a Kia Forte as you mentioned. Therefore, if you wanted to get your money back then you would need to return the Curt T-Connector Vehicle Wiring Harness part # C53KR and order part # 55057 instead.

There are existing holes with weldnuts already present. You will simply need a 17mm socket or wrench for installation. There are 4 bolts.

  • Can a 2017 Kia Forte Tow a Boat Trailer
    You can put a trailer hitch on your 2017 Kia Forte and for that I recommend the Curt Trailer Hitch Receiver part # C11368 if you have a sedan or part # C11395 if you have a hatchback. However, Kia does not recommend towing a trailer with this vehicle according to the owner's manual. If you choose to ignore this then in order to tow a trailer you are also going to need a trailer wiring harness part # C53KR, a ball mount part # C45521, and a hitch ball part # A-80 for 1-7/8" or part # A-82...
