Installation of Tekonsha T-One Connector

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located at the rear of your vehicle. Once you've plugged in the T-connector, run the body harness up to your car battery and connect the wires per the included instructions.

Once installation is complete, the 7-way 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 7-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 2-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's 3-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.

Installation of Tekonsha Brake Controller Adapter

This adapter plugs into the 4-pin connector on your vehicle's built-in brake control wiring harness. The harness is located near the steering column, through a grommet in the engine compartment.

This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

  • Parts Needed to Install 7-Way, 4-Way and Brake Controller on 2016 Hyundai Santa Fe Sport
    So since you have the factory tow package on your 2016 Hyundai Santa Fe Sport the first thing you need is the 7-way kit part # TK24FR that you referenced. This kit comes with wiring for a brake controller install so to install the Redarc Tow Pro Elite part # 331-EBRH-ACCV2 you'd just use the included wiring of the controller to splice then to the brake controller wiring and you'd have a really great and out of the way proportional brake controller. The only more discrete proportional...

  • Does Tekonsha OEM 7-Way Wiring Harness Fit 2019 Kia Sedona Without Factory Tow Package
    Yes, your 2019 Kia Sedona without the factory tow package is still compatible with the Tekonsha OEM Replacement Vehicle Wiring Harness with Brake Controller Adapter # TK24FR. According to the manufacturer, Tekonsha, this is compatible with all models of Kia Sedona and will plug into the tow package port which will be on your vehicle. This is compatible with the Tekonsha brake controllers, and for that I recommend the Tekonsha Prodigy P3 Trailer Brake Controller # 90195 as it is recognized...

  • What is Purpose of Blue Wire from 7-Way Kit # TK24FR
    The 16 gauge wire of the 7-way kit # TK24FR gets ran through the headliner of the vehicle to the reverse light circuit of the vehicle at the rear of the vehicle. If you don't need the reverse light circuit active on your 7-way you can skip this step.

  • Recommended 4 way and 7 Way Wiring Harness for 2021 Kia Sedona
    It sounds like you're looking for a solution to provide both a 4 way and 7 way trailer connector on the back of a 2021 Kia Sedona, and we've got exactly what you'll need. I'll start out by saying that the Tekonsha # TK24FR you were looking at only has a 7 way plug, so it's not going to be the correct part for this application. I recommend starting with the Curt # C56332 since it comes with a powered converter that will help protect the electrical components of the vehicle in the event...

This plugs into the brake controller wiring your vehicle has under the dash as well which means you'd be able to easily install a brake controller as well with it. For a brake controller the iCommand part # 5535 is the best value out there. It's proportional so it knows how hard you are applying the vehicle brakes and applies the...

  • Parts Needed to Safely Tow a Pop Up Camper with a 2016 Kia Sedona
    1. Normally I'd say that your 2016 Kia Sedona would be just fine as long as the pop up has brakes, but since your towing capacity without brakes is only 1,000 lbs it would be a good idea to install one. As far as the warranty is concerned you are protected by the Federal Magnuson-Moss Warranty Act. The Act states that if something breaks on your vehicle and you take it in for warranty repair, the dealer must honor your warranty unless whatever modifications you have added to your vehicle...
