CURT Custom Fit Vehicle Wiring - C56157

  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • 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.


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 - no cutting or splicing of wires
    • Locate connection points in rear cargo area
    • Plug in T-connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • 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 in your rear cargo area, behind the driver's-side and passenger's-side tail lights. You will have to remove the rear scuff panel and pull back the felt trunk liner to access these connection points.


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.

Excellent ! Was the quickest trailer wiring I ever did. Like plug and play with a computer.
Took longer to reinstall the trim pieces on my Kia Rio. God bless you.
Jesus is our hope for the future !

I ordered two hitches from trailer and they arrived before there scheduled time with all the instructions. They were easy to install. George J was very helpful with my questions.I would recommend them to anyone asking about a hitch plus they were the cheapest anywhere. Thanks

Kia Rio

got this for my Kia Rio. It was delivered quickly and was easy to install. Instructions were good. Only issue I had was with the two sided tape used to secure the module to a flat surface, it was not sticky enough to hold. I got my own tape and secured it, not a big deal, overall happy with this.

  • Trailer Hitch for 2013 Kia Rio EX Sedan
    I have a solution for you, but a hitch from a 2004 Hyundai Accent will not fit on a 2013 Kia Rio Ex sedan; I understand the confusion since some of the hitches available for the 2013 Rio are also a fit on some Hyundai and Volkswagen models. Instead, you will want to use the Draw-Tite # 24884, which is a confirmed fit on the 2013 Kia Rio sedans. If you're going to be towing a small, lightweight trailer with this hitch, you'll need a few other components for a complete towing setup. I've...

  • Trailer Wiring Harness for a Massimo MSU400 Side by Side
    Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector Item # C56157 is for certain Kia vehicles and has not been tested or confirmed on side by sides like your Massimo MSU400. You will need to use a hardwire harness such as # 119178KIT to hardwire a trailer connector to your side by side.

  • Does this Wiring Harness for my 2013 Kia Rio 5 Connect to the Battery?
    You are correct, this wiring harness # C56157 does not need to connect to the car battery, confirmed by Curt and the installation instructions for this wiring harness. This harness draws power directly from the vehicle taillight circuits and plugs right into your 2013 Kia Rio's taillights. The installation process for this wiring harness is quick and easy. I have attached the installation instructions for this harness for you to check out. If you are also looking for a trailer hitch for...

  • Availability of Trailer Harness for 2013 Kia Rio Hatchback That Doesnt Require Power Wire
    All of the trailer wiring harnesses for your 2013 Kia Rio do require a hot lead to be run to the vehicle's battery. This is actually required on this particular vehicle to both combine the light circuits so they are compatible with standard trailer wiring and also to provide enough power to actually activate them. The factory wiring on the Rio isn't quite strong enough by itself to power separate lights on a trailer so it needs the battery's help. For your Kia Rio Hatchback you will need...

  • Trailer Hitch and Wiring for a 2013 Kia Rio Sedan
    Draw-Tite trailer hitch # 24884 can handle the roughly 800 pounds of loaded trailer that you want to tow. But you have to check with Kia or your owner's manual to determine what, if any, towing capacity your 2013 Rio sedan has. I was unable to locate that information. In addition to the hitch you will also need the recommended ball mount # 3592 and a ball. For a 1-7/8 inch ball use # 19257 and for a 2 inch use # 19258. And for trailer wiring use # C56157 to add a 4-Way flat connector to...

  • Will Curt Trailer Wiring Harness Work on 2013 Kia Rio
    The Curt T-Connector Vehicle Wiring Harness # C56157 will not damage the wiring of your 2013 Kia Rio. This harness is custom made for your Rio and plugs directly into the existing wiring in the rear cargo area, behind both tail lights. It has an included tail light converter so that the Rio's matches your trailer's. If you need a trailer hitch as well, the Draw-Tite Sportframe # 24884 is a confirmed fit for the Rio. This is a Class I hitch receiver rated for 2000 pounds towing and 200...

  • Curt Trailer Hitch Compatible with a 2015 or 2016 Kia Rio
    Yes, the Curt # C11250 will fit both a 2015 and a 2016 Kia Rio Sedan. I have attached an installation video for a 2013 Hyundai Accent for this same trailer hitch that you can use as a reference. For a complete towing setup you will also need a ball mount kit and wiring. A popular ball mount option is the Curt Euro Style Drawbar # C45572 which you can secure in your hitch receiver with the pin and clip # F-4. Then for wiring I recommend going with the Curt T-Connector # C56157. To install...
