2023 Kia Sportage - Curt T-Connector Vehicle Wiring Harness with 4-Way Flat Trailer Connector

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your Kia Sportage with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and 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)
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Connects quickly and easily

  • Constructed using surface-mount technology (SMT) for consistent, reliable performance

    • Ensures superior operation in rough road conditions
  • Includes female 4-way flat connector with dust cap


Specs:

  • Maximum amperage:
    • Stop and turn lights: 3 amps per circuit
    • Tail lights: 6 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 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.

2023KiaSportage

When ordering the wiring harness I asked about installation. They told me it is a custom harness that just plugs in line with the vehicle brake lights. I received the harness and this is not the case. The rep that initially spoke to me about the harness clearly did not know what they were talking about. Still not that complicated but significantly more complicated than getting an OEM 4 pin connector kit.




by:

Arrived on time intact. Install was aided greatly by u-tube & was not difficult. I have plenty of mechanical ability but utube made it a snap as removal of tail lights made me fearful of breaking 1 of them. Perfect solution made easy with Battery in tailgate deck above spare tire.




by:
2023KiaSportage

The product came with all the required materials and it was sufficient to install. However it was not easy getting the battery wire from the front to the back of the Kia Sportage 2023. It's not the products fault, it's just the way Kia designed their setup. It took me a good couple of hours to find a route safe enough for the battery wire. All in all, it was a good install.




by:

All the parts are clearly labeled and the schematics are easy to follow. Apparantly the entire tail light mounting of the 2023 KIA Sportage has been modified and no longer accessed in the same manner as previous years.

  • Recommended Hitch and Wiring Harness Installation Method on a 2023 Kia Sportage Hybrid
    The reason you can't use a fuse tap to install the T-One Vehicle Wiring Harness item # TK32VR, on your Sportage Hybrid, is because the moduLite power converter has to have a constant supply directly from your battery. Without this direct source of power you would experience flickering lights, blown fuses, and that converter would eventually fail. Wiring it with a fuse tap would also void any warranties.

  • Is Running a Power Wire to the Battery Required for Trailer Wiring on a 2023 Kia Sportage
    It sounds like you're considering installing a trailer wiring harness on a 2023 Kia Sportage for towing. If that's the case then great we do have options for this along with everything else you need to tow. That said, all of which require running a power wire to the battery. This is actually rather important as it allows you to send power to the trailer lights using the vehicle's battery and not the vehicle's tail light circuits which could short out from the additional load or cause a...

    The best 2" hitch for a 2023 Kia Sportage is going to be the etrailer Hitch item # e38KR. This hitch is custom fit and bolts directly to your Kia with included hardware.
