CURT Custom Fit Vehicle Wiring - C56382

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. Connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.


  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection point in rear cargo area
    • Plug in connector
  • Includes a tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side interior trim panel in your rear cargo area. Once you've plugged in the T-connector, insert the included 10-amp fuse into the integrated fuse holder. Then install the 30-amp cartridge fuse and two 7.5-amp mini fuses in the rear fuse panel.

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

It is recommended that you use a small amount of grease on all electrical connections - the plug 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.

Installed myself in about 15 minutes, connects to rear fuse panel in driver side rear cargo compartment of 2019 Honda Odyssey. There is enough room to fold it up and stow it behind the fuse panel door, out of sight until it's needed. I don't use a trailer very often, but as cheap as this kit is, having the ability to connect a trailer and its lights was a no-brainer.

2020 Honda Odyssey

Great price - easy to install- only wish the cable was longer to run outside the car. Fortunately there are extension cables available.

I know I wished the cable was longer before, instead its perfect. Use the extension cable and you never have to worry about your primary cable being destroyed for any reason. Like when your spouse crushes it with luggage in the trunk.
mark d - 08/22/2022


Total installation was about 3o minutes and works perfectly. Great instructions made it quite simple. Far cheaper than having it done. Recommend getting a traier test light plug.

Product is still working fine. Would recommend to any one.
Gary - 03/12/2022


Working great on my BMW e46 xiT. Pretty easy install if you have a voltmeter and a brain.


I rec’d email from Carol C at Etrailer at 7:01pm devising my order had been delivered and a link to this survey. I responded at 7:02 I had not rec’d my order.I did not expect a response. At 7:18 I rec’d another email advising they had called UPS and the order was left by the shed at the road. I found the box there. This is Customer Service at it’s finest? My second order from etrailer, and won’t be my last!

No issues

Once installed, no muss no fuss - what can be better?


Following the instillation instructions was straightforward and resulted in a very cleanly installed unit.


easy to install and works great


Instructions were legit and helped tremendously to make this a quick and easy instal in my 2021 Honda Odyssey!

Literally plug and play

2022 Honda Odyssey

Install was easy. All the components that you need are there and then some. Would be great if the harness was outside of the vehicle, but I guess that's on Honda.


Happy with purchase. Easy to install- wish it would have come with a bracket or mounting plate to attach the wiring harness to the hitch frame.

2018 Honda Odyssey

Install was easy. It was basically plug and play except for attaching the ground. I keep the trailer wire hidden behind the rear fuse box access panel and bring it out when I need to hook up the trailer. It is no problem closing the hatch on the wire as long as you keep it away from the latch. Everything works fine with the trailer lights.


This wiring harness was easy to install and works perfectly. I've seen alternatives which require feeding wires all the way from the engine bay, and that is totally nuts. Don't waste your time and energy. This installs from the rear corner, right where you're already working on the hitch install. Choose this item -- it's perfect.


Very very good service. Can’t find that everywhere these days


Great plug & play harness. Would definitely buy it again.

2022 Honda Odyssey

Installed easily. The only thing is that the four pin plug wire is about one foot too short.No reason to be that short.I could not get the two sided sticky foam pad to stick to any part of the car


Easy to install system as shown in recommended installation video. I used it to haul a 6x12 trailer I rented from a U-Haul. Haven’t tucked the wiring and harness away to look professional yet.


Installation went smoothly. Instructions were clear and easy to follow.


Super easy install with the help of your installation videos. Don’t be intimidated, do it yourself and save the dough!

2018 Honda Odyssey

This wiring harness was easy to install, if you follow the video.

Works as expected.

Thought the wire to the trailer was a little short, but when installed it was at the correct length.


I'm quite happy with the Curt wiring kit. It took me about 25 minutes to install and didn't have too many pieces to hook up. You also don't need to splice wires or run a wire up to the battery. The van already came setup to plug the cord in and use it. I have the vacuum cleaner in my van and that made it a little tighter to work, but it still worked out great. I tested it out on the trailer and everything worked perfectly.

2020 Honda Odyssey

Instructions were not good, but U-Haul had a great youtube video. Also, you should include that you have to buy to hold wires to trailer hitch. But worked good.

2018 Honda Odyssey

Wow is all I can say! Several friends recommended and I will happily do the same. I ordered the products, I recived a confirmation email (from a human) that it was packed up and shipped to me. It arrived error free and packaged well. I logged in and instruction videos that were just what I ordered (no searching for what I needed) were spot on and easy to follow. I am beyond impressed from start to finish
and the best part is its on and we are towing! A big thank you to the people that put this together for me!

2018 Honda Odyssey

quick install....helpful video & instructions ...good price & fast shipment. This is my 3rd harness & hitch install from e-trailer in 5 tears...with no problems.

  • Difference between Item # C56382 and Item # 118753 for a 2018 Honda Odyssey
    The difference between the Curt # C56382 and the Tekonsha T-One # 118753 for your 2018 Honda Odyssey is that the Curt is for if the fuse locations actually have pins in them. The Tekonsha option is for if the fuse locations are lacking the pins to activate the tow wiring. The Tekonsha basically bypasses everything and pulls power straight from the battery via the black wire (which runs to your battery) while the Curt utilizes factory wiring on your vehicle.

  • Difference Between Tekonsha 118781 and Curt C56382 Trailer Wiring Harness for 2019 Honda Odyssey
    Both the Tekonsha T-One # 118781 and Curt T-Connector # C56382 are custom trailer wiring harnesses confirmed to fit your 2019 Honda Odyssey, but I do recommend the Tekonsha # 118781 for a couple reasons. First, the Tekonsha harness does feature a higher amp rating (max 5 amps for stop/turn circuits and 7.5 amps for tail lights compared to 3 amps and 6 amps respectively on the Curt), which just offers a stronger system that's able to take a bit more power. In addition to the higher amp...

In terms of function and install these are identical, however I do recommend the Tekonsha # 118781 because it features a higher amp capacity and a superior converter box, which has proven to have a longer lifespan than those from other manufacturers.

  • Choosing Between Tekonsha or Curt Powered Taillight Converter/Wiring Harness for 2020 Honda Odyssey
    Functionally speaking, there isn't a huge difference. The Curt # C56382 has a slightly lower capacity at 3 amps for circuit for stop/turn signals and 6 amps for taillights. The Tekonsha # 118781 has a capacity of 5 amps per stop/turn circuit and 7.5 amps for circuit for taillights. Honestly, you'll probably never need the added capacity unless you're towing something that's lit up like a Christmas tree but having a little unneeded wiggle room as far as capacity goes never hurts.

    I can see why this might be confusing and there are some differences between all 3 of these wiring harnesses. I'll start off by explaining the differences between the Tekonsha # 118781 and # 118753 wiring harnesses. The main difference is that the # 118753 is designed for vehicles that do not have the towing fuses already in place. In order to determine which one you can use on your 2020 Honda Odyssey you'll need to check the rear interior fuse box, which is located on the left side of...

    As long as your 2020 Honda Odyssey doesn't fall into the extremely rare category of Odysseys that are missing terminals on fuse locations #10, #11 and #12 inside the fuse box, your best option is to go with the Tekonsha # 118781. Curt offers a similar option with the # C56382, but in our experience, the Tekonsha harnesses, and their converter boxes in particular, seem to do a better job and have proven to outlast the competition.

    It would seem odd that you would receive 2 defective Curt T-Connector Vehicle Wiring Harnesses # C56382 for your 2019 Honda Odyssey. The first place I would like to start is at the 4-way connector. A Test Light # PTW2993 is the best way to check the wiring.

The reason why this is a better bet than the competing harnesses like the Curt # C56382 is because the T-One includes a better quality converter box.

Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way.
