Tekonsha Custom Fit Vehicle Wiring - TK26FR

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

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.

    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery

    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector

    • Tail lights: 7.5 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One 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.


T-One Connection Location Points Behind Tail Lights

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 and insert the provided fuse.


Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


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.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One 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 your trailer. This power module functions as a tail light converter to combine 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.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

  • How Do I Tell if I Have a Factory Tow Package on My 2022 Kia Sorento?
    In order to tell if you have a factory tow package on your 2022 Kia Sorento, there will be tail light wiring connectors behind the rear driver's side tire. This will be on the exterior of the frame rail. In order to see these ports, you will have to remove the underbody cover in order to expose those connectors. I went ahead and attached a photo of what these connectors look like on a 2020 model. Your will look very similar. If you discover that you do not have the factory tow package,...

  • Will Tekonsha Powered Taillight Converter Draw Power When Vehicle is Off
    The Tekonsha # TK26FR T-One connector will not draw power from the tow vehicle unless the trailer lights are illuminated. Although it isn't necessary to do so, you could pull the 10A fuse from the holder where it connects to the battery when you're not towing if you wish. We don't recommend connecting that power wire in any other manner that a direct connection to the positive battery terminal. If you draw the power from the 12-v socket, you'll be pulling power for the trailer lights through...

  • Recommended Trailer Wiring Harness for 2021 Kia Sorento with Factory Tow Package
    I do have an option for you though we don't offer any factory tow package wiring harnesses for a 2021 Kia Sorento. Instead, you will need to use one that plugs in behind the tail lights which will work whether or not you have any sort of factory tow package. For this, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # TK26FR which provides a standard 4-way flat connector.

This means no cutting or splicing is required. You will also need to run a hot lead to the car battery to complete the...

    There really won't be able to tell if your 2021 Kia Sorrento is wired for the trailer lights. If you bought the vehicle with the towing package, then the wires will be incorporated in the factory harness. Right now, there is only one plug in style adapter # TK26FR available right now for your Sorrento that does not require splicing into the factory wiring. There will be a connector located behind the driver's-side and passenger's-side tail lights. You will have to remove the tail light...

  • Trailer Wiring for 2022 Kia Sorento Hybrid without Tow Package
    If your 2022 Kia Sorento does not have the factory tow package it would not have the connector needed to install the part # 118269 that you have. If that's the case the other option would be the trailer wiring kit part # TK26FR which installs by plugging inline with the taillight connectors of the vehicle and was designed for vehicles without the tow package.

    The T-One Vehicle Wiring Harness # 118269 would be the correct wiring harness if you have the factory tow package on your 2022 Kia Sorento. The # 118269 would plug into your vehicle's factory tow package wiring harness, which is located along the frame rail at the rear of your vehicle. This would be the option that requires the least amount of disassembly of your Sorento. If you do not have the factory tow package then you would want to use the T-One Vehicle Wiring Harness # TK26FR (which...

  • Could Tekonsha Trailer Wiring of 2021 Kia Sorento be Used for Brake Controller Install Brake Circuit
    This is a really good question. Technically you can use the red wire of the # TK26FR that is before the converter box for the red wire of your brake controller install with the # ETBC7 since this is a dedicated stoplight circuit. Normally you have to run to the brake pedal but this is a clever way around having to do that. A lot of vehicles have the stoplight circuit combined on the turn signal circuit so this isn't possible.

    For your 2022 Kia Sorento we have plug and play trailer wiring kits like the part # TK26FR which plug inline with your vehicle's taillight harnesses. It does require running a wire up to the vehicle battery which protects the taillight circuits of your vehicle. It does this by only using the taillight circuits of the vehicle as signal wires and then draws the amperage needed for the trailer taillights from the vehicle battery instead. This does make the install a little more involved but...
