Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side tail light housing in your trunk.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your trunk.


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 with Surface-Mount Technology

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.


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.

Video Transcript for Review of Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C54ER

Jeff Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this Curt T-connector vehicle wiring harness with the four-way flat trailer connector. Now, this is a custom-fit part. It is designed to fit the 2019 and newer Kia Forte sedan vehicles. And on a custom-fit part like this, I do like to recommend for you to go to the website.

Use the fit guide. Put in your year and model vehicle. And it'll show if this'll work for your application. Now, this will provide this four-way flat trailer connector at the back of your vehicle to power your trailer's signal lights. And it is compatible with five-pole, six-pole and seven-pole adapters that we do sell separately on our website.

This kit does connect very quickly and easily. Just locate your connection points which are on the vehicle. There'll be one behind the driver's side tail light inside of the trunk. There'll be one behind the driver's side rear bumper. And there's one behind the passenger side rear bumper.

Plug in these T-connectors right here to those connection points. Ground your white wire right here. And then, run this power wire to your vehicle's battery. If you notice this black box here, this is the tail light converter. This is to ensure that your vehicles wiring will match that of your trailer.

And it is a power module. That's why it'll connect directly to the battery to avoid overloading your vehicle's electrical system. This converter is constructed using SMT technology, which is surface-mount technology. Gives you more consistent, reliable performance. It'll maximize your trailer light yield and intensity while producing minimal heat. And it does ensure superior operation in rough road conditions. If you notice on the four-way, it does come with this nice dust cover for the four-way. So, when it's not being used, you can just put the cover on there, and it protects those terminals from any damage or from any elements. A few specs on this. The maximum amperage for the stop and turn light circuit is three amps per side. Tail lights is six amps total. Does include everything shown here on the table. Comes with a nice set of instructions on how this installs. But basically, what you end up doing is after you make your T-connectors right here, after you plugged those all in, what you wanna do is this black box here. This converter box does have some weight to it, so you do wanna attach it to a good flat surface so it doesn't bounce around. So, they do include a piece of double face tape that you can use for that. And then, run your four-way out towards the back. And then, you'll have two remaining wires, the white wire and the black wire. The white wire will have an eyelet on it. That's for a ground. So, if there's a nearby ground you can connect this to, if not, they do include a grounding screw that you can make your own ground. And then, there's a black power wire. This needs to run to the front of the vehicle to the vehicle's battery. And they do give you the extra wire and connectors to do that. So, what you'll do is take the connector. Put it on this end. And then, run your length of wire up to the front. Now, when you do get to the front, you don't wanna connect this wire directly to the battery. You wanna run it through this inline fuse holder. Take your other butt connector. Connect it to one side of the fuse holder just like that. And then, on the other side of the fuse holder, you'll take this eyelid connector. Connect it onto there, and then, connect that to the battery. Once it's connected, pop it open. Take your included 10 amp fuse. Drop it into the fuse holder. Push it all the way in. Put your cap down on place. And then, your system's all ready to go. They do give you some extra cable ties to take up any slack in the wiring. Now some of the wiring has to go through some rubber grommets, so they do give you some tube of black silicone to help seal that up. But that should do it for the review on the Curt T-connector vehicle wiring harness with the four-way flat trailer connector..

  • Finding The Driver-Side Wiring Harness In My 2020 Kia Forte For A 4-Pole Flat Installation
    The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part # C54ER, has a plug behind the sidewall of the driver-side. It is not in the trunk because it is behind the sidewall. Unfortunately, we do not have a video of this installation. I was able to include diagrams from the installation instructions showing the sidewall and where to find the wiring harness connectors below.

  • Do You Have To Drill The Frame On the 2021 Kia Forte To Install the Curt Receiver?
    The Curt Trailer Hitch Receiver # C55HR does require holes to be drilled in the frame as there is currently only one hole on each side of the frame available for mounting the receiver. Each additional hole on each side of the frame is required to provide the strength to hold the receiver in place while being used. There currently are no hitches available that do not require drilling to install them on your 2021 Kia Forte. I recommend installing a Curt T-Connector Vehicle Wiring Harness...

  • Trailer Hitch Receiver and Wiring Harness That Will Not Obstruct Rear Camera On a 2021 Kia Forte
    The Curt Trailer Hitch Receiver # C55HR will not block the rear camera on your 2021 Kia Forte. I recommend installing the Curt T-Connector Vehicle Wiring Harness # C54ER when you install the receiver. This will give you a 4-way flat connector that is needed in the event you tow a small trailer. It will also allow you to use Auxiliary Lights # C53201 if your hitch mounted accessory impairs the view of your tail lights.

  • Recommended Hitch for a Bike Rack on a 2019 Kia Forte Ex
    I would be happy to help you and make a recommendation. You are extremely limited on options for your 2019 Kia Forte as there is only one hitch available. It is the Draw-Tite Sportframe Trailer Hitch Receiver item # DT83MR. This hitch is custom fit and bolts directly to your Kia with included hardware. It has a 1-1/4" receiver like the item # 24903 you were looking at. This hitch will be mostly concealed behind your Kia's rear trim with the exception of the receiver and safety chains that...

  • Can Curt C11368 Class I Hitch Be Removed From 2017 Kia Forte and Installed on 2020 Model
    The 2017 Kia Forte was the second to last model year of the 2nd generation Forte, while the 2020 is the second model year of the 3rd gen. There were enough changes in the structure of the vehicle from the 2nd to the 3rd gen that unfortunately your Curt # C11368 from your 2017 Forte will not work on your 2020 model. For the 2020 Forte sedan, I'd recommend the Curt # C55HR Class I hitch you'd looked at. As you can see in the photo I provided, once installed the # C55HR will be much more...
