  • Powered Converter

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into OEM tow package wiring harness - no cutting or splicing required.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Designed for use with a factory tow package
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing
    • Locate connection point behind rear bumper
    • Plug in connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
  • Protective connection terminals resist corrosion
  • Comes with dust cap for 4-way flat connector, cable ties, and terminal grease packet for electrical connections
  • 90-Day limited warranty


Installation

This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear tire, on the driver's side.


Once installation is complete, the 4-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 4-pole connector itself - to help prevent corrosion.


Tail Light Converter

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.

Video Transcript for Hopkins Plug-In Simple Wiring Harness Installation - 2019 Kia Sorento

Today in our 2019 Kia Sorento, we're going to be installing Hopkins plugin simple wiring harness with four pole flat trailer connector. This four pole wiring harness is going to provide you with all the necessary lighting. This include your left turn signal, right turn signal, tail lamps, and brake lamps, keeping you DOT compliant in all states. What else is nice about this harness is that it's custom fit for your vehicle, so it plugs right into your factory tow package connectors, making it a quick and easy installation. The module that's installed in your harness will provide overload and short circuit protection. So if you have any faults in your trailer, you don't have to worry about it causing any damage to your vehicle.

We'll begin our installation under the vehicle on the driver's side at the rear. We're going to need to remove the undercover located here to access our factory wiring connectors. There's two pins that hold it in. You're going to use a flat bladed screwdriver or trim panel tool to pop out the center, and then you can pull the pin out. Once you remove both pins, simply pull down on the panel.It is connected at the top on some studs, but it just pulls right off of them.

Your two connectors located here are your factory wiring connectors. You'll want to remove the dummy plugs in the end. You'll simply push in on the release and pull it out. We'll do the same thing on the other one here. Your release tabs are going to look like that.

They're going to stick out a little bit, and they'll move when you press on them. Same with the other one here. We can now take our harness and we're going to plug it into those factory wiring connectors. Once you got them both plugged in, we can secure our module up. We're using the zip ties to secure it that come included with our kit.

We can then route our four pole over to our hitch, and install our dust cap. I like to use the dust cap to secure it to the hitch to keep it up out of the way. You can now reinstall your under panel.Now, in order for the wiring to pass through, it may be necessary to trim it. We're not going to do any trimming on our panel today for demonstration purposes, so we're just going to leave it off. And it's okay if you just want to leave it off as well. Now we can test it out. You can plug in a tester, like the one we have here, or you can just plug it into your trailer. You want to verify that you have your left turn signal, right turn signal, tail lamps, and brake lamps. With everything working properly, we're ready to hit the road. And that completes our installation of Hopkins plugin simple wiring harness with four pole flat trailer connector, on our 2019 Kia Sorento.

A good product from etrailer. Installation for both hitch and wiring harness is very easy when following directions on Youtube for 2016 model KIA. Kind of a hassle getting the wiring up under the bumper. Customer service and delivery were excellent - wish that I had more occasions to work with and get direction from a company like etrailer.

  • Parts Needed to Install 7-Way and Brake Controller on 2016 Kia Sedona
    We certainly can help you set up trailer wiring on your 2016 Kia Sedona that will allow you to use your trailer brakes and battery charge wire, but you do have to start with a 4-way like the # HM11143965 that you referenced. Not all vehicles are wired for trailer brakes. Especially ones that weren't made with towing as a primary concern like your 2016 Kia Sedona. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will...
