Features to know about

Installs Without Cutting or Splicing: Plug-In 4-Flat Harness

Wiring for trailer lights doesn’t have to mean cutting into factory wires. The Curt T-Connector plugs directly into the existing wiring with no splicing. It’s a clean, hidden connection that adds a 4-pole flat trailer connector ready for running lights, turn signals, and brake lights.

Adds Reliable Lighting for Tow Dollies and Small Trailers: 4-Pole Flat Output

When you just need basic trailer lighting, the built-in 4-flat connector makes it simple. It provides the standard light functions so your tow dolly or small trailer lights work exactly as they should. Everything stays synced with the vehicle’s signals for safe, visible towing.

Fast DIY Setup: Plug and Lead Design

The plug-and-lead setup keeps the install quick and straightforward. You connect the T-harness behind the tail lights, route the converter box, and you’re done. No guesswork on wire colors or tracing circuits—just matched connectors that fit right where they should.

Clean Factory-Look Finish: Hidden Converter and Vehicle-End Connector

Once installed, the harness tucks neatly out of sight. The converter and vehicle-end connector sit behind panels or under trim so nothing dangles or looks out of place. You get a tidy finish that looks like it came from the factory.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C56228 Review

Speaker 1: Today we're taking a look at the Curt T-Connector Vehicle Wiring Harness with a 4-Pole Flat Trailer Connector. This product fits certain years of the Kia Forte5 Hatchback. To ensure that it is a fit for your vehicle you can always use the vehicle fit guide located at etrailer.com.Now, this unit provides a 4-way flat connector at the back of your vehicle, to power your trailer's signal lights. It is compatible with 5-pole, 6-pole, and 7-pole adapters, adapters are sold separately, and it comes with the dust cap for the 4-way flat connector, that way you can cover up the connection points when your plug's not being used. The black box is the included taillight converter, this ensures that your vehicle's wiring matches that of your trailer's. It's constructed using surface mount technology for consistent, reliable performance, and what that does is, it maximizes the trailer light yield and intensity, while producing minimal heat, and it ensures superior operation even in rough road conditions.Now, this unit is designed to connect quickly and easily, so you don't have to worry about cutting or splicing any wires.

All you need to do is locate the connection points in the rear cargo area, and plug in your connectors. One will be favored towards the driver's side, and then the other one will be favored towards the passenger's side. So these connectors are custom fit for your vehicle, meaning, they're gonna match up perfectly with the ports on the vehicle, and they snap-lock together for a nice, tight, secure fit. So get those plugged in, and then you'll need to make a ground connection, that's your white wire with a ring terminal already attached to it, so you wanna get that ground at a suitable grounding location with the included grounding screw. And then you'll need to mount your converter box to a safe, out of the way location.

You can do that with the included cable ties, as well as the double sided adhesive foam tape.Once you have that done you can secure any excess, or slack, in your wiring with the included cable ties, and once your installation is complete, the 4-way connectors will be stowed in an out of the way location within your trunk. There's plenty of wiring here, so you can extend it out the back of the vehicle when you need to use it, roll it up and tuck it away when you don't. It is recommended that you use a small amount of dielectric grease on your electrical connections, like the plugs on the vehicle and the 4-pole connector itself; that grease is specifically designed to prevent corrosion of the connection points. It is sold separately, and available at etrailer.com if you need some. When it comes to the maximum amperage for the stop and turn lights, we're looking at three amps per circuit.

For the taillights we're looking at five amps per circuit.That's gonna do it for today's look at the Curt T-Connector Vehicle Wiring Harness with a 4-Pole Flat Trailer Connector.

  • Recommended Trailer Hitch for a 2017 KIA Forte 5 Door Hatchback
    I have a solution for you but the item # C11368 hitch you were looking at will not fit the hatchback model of your 2017 Kia Forte. Instead you will want the Curt Trailer Hitch item # C11395. This hitch is custom fit and bolts directly to your Kia with included hardware. It has the same capacity as the hitch you were looking at. If you need a wiring harness to control your trailer or accessories lighting functions you will want the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat...

  • Recommended Trailer Hitch Receiver for 2016 Kia Forte 5 Hatchback
    For a 2016 Kia Forte 5 Hatchback, you will want the Curt Trailer Hitch # C11395 which is a confirmed fit. If you plan on doing some light towing with that hitch, I recommend the ball mount # C45521 along with pin and clip # F-4 and a hitch ball like # A-80 for a 1-7/8 inch diameter or # A-82 for a 2 inch ball. For your wiring, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56228. This harness connects to your factory harness behind your...

If you'll be using the hitch as the attachment point for a bike rack or a cargo carrier, be aware that Curt's hitch warranty stipulates that a stabilizing strap like part # 18050 must be used for non-trailer loads.

  • Trailer Wiring Harness for a 2016 Kia Forte5
    Your 2016 Kia Foret5 looks to have a max towing weight of 1,800 lbs which would mean that the largest hitch you could have is a class I hitch. With a class I hitch you're not really equipped to tow, it's more suited for hitch mounted accessories. With that being said, you can use the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56228 to add a 4-way to your Kia Forte which would get plugged into your tow dolly and provide lights.
