This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your cargo area. You will have to remove all trunk floor coverings, storage trays, and the scuff panel to access these connection points. Once you've plugged in the T-connector, run the hot lead 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.

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.

Powered Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.

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.

Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - C56284

Average Customer Rating:  4.7 out of 5 stars   (35 Customer Reviews)

Hitch and wiring I purchased with it arrived promptly and have been applied to my car so I can now use a low mounting bike rack. (I no longer have to lift bikes above my shoulders to transport them.) I can use a small trailer to haul 4 kayaks/bikes when enjoying outdoors with friends or haul necessary project items like bags of mulch. All lights on trailer working appropriately with this wiring.


This took me about 2 hours to install. It was difficult to get under the car and route the wiring around the moving parts to the battery. Be patient and allow plenty of time. I did not have access to a car lift. That would have made it much easier.

2016 Honda HR-V

I've never installed a hitch or wiring before and was kind of intimidated to install it.

This was by far the easiest hardest thing I've done to a car. I'd rate the difficulty level as changing a flat tire on the side of the road.

I installed this at night using a flashlight, by myself.

The hitch came in a box and included all the hardware necessary to install. I didn't need any special tools (you could use a torque if you wanted to too, but I used a pry bar and cracked it down).

The wiring was the most annoying part as I had to run the power up to the battery, the annoying part was the driveway was wet from rain. (Oh I would suggest a different wiring coupler, twist-on couplers aren't great)

Price: The price of the hitch receiver and wiring, was pretty great for the quality of product I received.

I got everything installed and tested and had no issues with lights etc.

The hitch and wiring came with instructions, however these should be improved. The layout of the instructions were messy and difficult to follow. Additional diagrams for each step would be helpful.

Company Experience:
My experience with the company was great. I placed my order online, had an issue with billing address (my fault) and they reached out immediately with remedial actions. I placed a new order and received confirmation along each step of the order to shipping to it being delivered. That's good customer service (even if it is automated or not).

Everything was pretty smooth, the quality of product versus price was great, delivery was quick. I would certainly do business with etrailer again.

When installing a trailer hitch, it is important to make sure to use a torque wrench to torque the bolts down to the specifications stated in the instructions to ensure the hitchs integrity.

As with every order we have made with etrailer, must say excellent, from the customer assistance to the actual products. The trailer hitch for my friends Honda is perfect. Thanks this is the way all companies should be.


The harness has worked properly without problems. The only thing I don't like is the fact that a wire has to be run the entire length of the car to draw power from the battery. While the connectors and wiring in the rest of the kit were of good quality and well thought out, the wire to the battery was just a coil of wire, a hand full of zip ties, and a "you figure it out" on the instruction sheet.

Years ago, the car manufacturers used wire of sufficient gauge that the additional power needed for trailer lighting was drawn through the vehicles taillight circuits without issue. As the complexity of vehicle wiring systems and the price of copper increased, smaller gauge wire started being used. The result of this is that the power needed for trailer lights now must be drawn directly from the vehicle battery. This does indeed make for a more complicated installation, but this manner of connection has the huge benefit of keeping the complicated and expensive to repair vehicle lighting isolated from the trailer wiring. As trailer wiring is more exposed to road hazards, this is a good thing.

Looks like everything’s there, looking forward to putting it on the vehicle but the last time I ordered this harness it was right on the money and it’s essentially the same car so I’m not expecting any problems.


Easy to install. Has worked great so fa r.

2016 Honda HR-V

Exactly what it says it is - easy enough to install, works as promised.

Maybe consider offering a version of this which includes the $5 tester, and a small tube of dielectric grease? That would permit folks to install without making a 'parts / supplies' run in the middle of the installation.

2017 Honda HR-V

The wiring harness worked like a charm! Everything worked as advertised.

Worked great.
Just wish the cables from
the box to the light connections were a little longer.


I revieved my package and everything looks good just have to install it. Love ordering from here. I ordered my hitch from here and it got here quick just like the wiring. will definately keep ordering from you when need too

2017 Honda HR-V

Excellent fit. This kit seems updated as the hardware was a little different than the video, but I think adapted for that muffler issue. I installed in about an hour not including watching the video.


great product even better customer service from etrailer!


Ordering a delivery was great, product is exactly what I was looking for. Would by from etrailer again.

  • Installation Of Curt Trailer Wiring Harness On 2016 Honda HR-V
    I am sorry the instructions were not in the package you received with the Curt wiring harness, part # C56284. I have linked the installation instructions you can check out. As far as the trim panel, in the instructions and in the tools needed a trim panel removal tool is listed. We do offer those in a kit as a separate item. The kit is part # ALL647989. Step 4 describes how to remove the trim panel at the back of your vehicle. I talked to one of our installers and they told me the panel...

  • Brake Controller Recommendation for a 2016 Honda HR-V
    For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. This is a proportional brake controller that senses the amount of braking the tow vehicle is applying and applies a proportionate amount to the trailer brakes. You will need to start with a 4-way (if you do not have one). For that you would want the # C56284. From there you would need to convert the 4-way...

  • Trailer Hitch and Wiring for a 2016 Honda HR-V
    Yes, for your 2016 Honda HR-V you can use Draw-Tite trailer hitch # 24932. Ball mount # 3593 is the correct ball mount if you intend to do any light duty towing. For a 1-7/8 inch ball use # 19256 and for a 2 inch ball use # 19258. And for trailer wiring you can use # C56284 to add a 4-Way trailer connector. If you want to use the hitch for an accessory such as a bike rack or cargo carrier then you have to make sure the accessory is rated for use with a Class I trailer hitch. Also, with...

  • Recommended Trailer Hitch And Trailer Wiring For 2016 Honda HRV
    I recommend the Draw-Tite Sportframe Trailer Hitch, part # 24932. This is a Class l hitch and it has a 1-1/4 inch receiver opening. You will need a ball mount and ball so I recommend part # 3593 for a ball mount. This comes with a hitch pin and clip. For a 2-inch hitch ball I recommend part # 19258 and for a 1-7/8 inch ball you can use part # 19256. Since you plan on towing you will also need a trailer connector if you do not have one. For that I recommend part # C56284.
