Features to know about

Installs Cleanly Without Cutting Wires: Plug-In T-Connector

Wiring up a trailer can be intimidating, but this Curt T-Connector keeps it simple. It plugs directly in line with the vehicle’s tail light wiring to create a 4-flat connector. There’s no need to cut or splice anything—just match the connectors and plug them in. The result is a clean, reliable setup that’s ready for the road.

Built for Trailer Lighting Basics: 4-Flat Connector Output

This harness provides the standard 4-way flat connection for trailer running lights, brake lights, and turn signals. It’s the most common setup for small and mid-size trailers, so you can hook up and go without adapters or extra wiring. Everything you need for basic trailer lighting is right here.

Quick Setup with Behind-the-Panel Access: Factory Connector Fit

The factory connectors are located behind trunk trim panels, keeping the install neat and protected from damage. Once those panels are pulled back, the plugs click right into place. It’s a straightforward design that makes routing wires simple and keeps everything tucked away where it belongs.

Reliable Power and Signal Transfer: Integrated Converter Design

The built-in converter ensures the trailer lights get clean signals without overloading the vehicle’s electrical system. It’s designed to protect factory wiring while delivering consistent performance for every trip. Once connected, the harness works seamlessly with standard trailer lighting every time you tow.

2007 Honda Accord

Connectors do not fit a 2007 Honda Accord VP. Nothing for the green connector to connect to, only one place found on my car for one of the 3 way connectors. Nothing in the instructions photos the wiring in my car.

Hi Craig, is your Accord a sedan or the coupe model? The harness you purchased is a confirmed fit for the sedan, but not the coupe....

Hitch and wiring are good quality, shipping was very prompt, pricing best I found searching around...

Additionally instructions were clear and complete.
I am very satisfied with my purchase, and my dealings with eTrailer.

the wiring harness works like a champ. Very tidy, and not asingle issue. I use it several times a year when Im hauling my motorcycle to the track.

by: Keith 12/22/2025 One Year Later

Product arrived packed well and great shipping. Opened box and all connectors were wrong ends and none of it fit my car. Called and returned product. All the other products I have ordered are great and worked well. You are a great company providing the consumer with needed items, keep up the good work!!!

by: James 03/31/2022 One Year Later

Awesome and super easy to install - fits and works perfectly in my 2012 Honda Accord and confident that the install is secure. Completely satisfied with this product. Picture shows what the CURT Hitch and T-Connector allowed me to attach to the Honda - trailer has 1720 lb weight capacity - so my reliable honda turns into a 3/4 ton pick up when needed.

2010 Honda Accord

Great product. This one utilized the reserved tow light connector on my Accord, unlike other products (they have long green wire) that need to take off both liner to access left and right signal wires, I just need to take off the left liner and every socket you need is there.

by: George 08/21/2025

It took a bit to figure out how to hook up the snap-in connecters but once figured out I realized that there was not enough wire to reach across the trunk so that each light was connected. I needed to splice two wires (had to cut the wires first and then added wire that I had in my tool box). I was suprised that a custom wire harness would need to be spliced, but at least the connectors were spot on.

Product worked as expected. I called customer service to ask a question about the part ordered. Blake was able to verify i ordered the correct wiring kit for my hitch. I feel confident each time I do business with etrailer. Great job folks at etrailer!

by: Mariah 08/14/2023

Does not fit my 2004 Honda as mine doesn’t have anything to hook into the green plug. Link for this product says it will match my car and be an easy hookup. It was not and doesn’t work. We were scheduled to take our first trailer on a camp trip in 4 days and after this arrived 3 days later than shipping promised, we weren’t able to trouble shoot and order any other option. Very disappointed and left in a huge jam for our trip .

I know that finding the connector can sometimes be tricky. Do you have the sedan or couple Honda Accord? The connector should look like the one in the picture in the manual. Can you take a picture of what you are seeing?

by: Charles 08/17/2020

I searched everywhere. I could find a harness for my car but not one with the plugs. I did not want to cut up a perfectly good harness in my car if I didn’t have to. The manufacture’s website showed they made them but none were available. From now e trailer will be my first stop.

Easy to install. Done in 30 minutes. No problem. Been using it for a year or so. Still no problem.

by: Rich G 05/25/2013

Watch the video on eTrailer on the install -- the included paper instructions are pretty confusing, but installation is VERY EASY. Really nice that the connector hides in the spare tire and just hangs out the trunk when you need it (rather than drilling through the floor to store the connector outside the car). No soldering, no cutting wires, just plug in and reattach your trunk panel. The first time doing this took ~15 minutes, but now that I know where everything is you could easily do this in 5 minutes.

by: Dan B. 05/27/2015

As outlined in my hitch review I also purchased etrailer's wiring harness. Make sure you find a video on utube that shows you how to remove the back trunk panels. It would be eazy to break the plastic mounting pins. I found one that showed how in a video on attaching a wiring harness. It was a easy as one two three. Just unsnap each of the three tailights from their factory plugs, replug each of the wiring plugs on the wiring harness and replug the factory plugs into the wiring harness.additional leads. You cannot plug into the wrong one as each is unique to its own. Place a couple of tie downs on the harness to anchor it. I placed the end of the harness plug into my spare tire well, replaced the trunk panels and job done. When I need to plug in the harness to my trailer I just lift my spare tire cover, pull out the desired length to reach the traile plug and close the trunk lid.

by: Jon 01/28/2023 One Year Later

Hell. Yes. This thing is awesome. I had a wire tap version professionally installed previously (part not from etrailer) and it was such a pain! There was a short or something in the wires and it'd kill my cruise control when I'd use my blinker... Imagine that while trying to leisurely pass a vehicle on the interstate... Anyway! This product just clips inline with your existing cables and forget about it! No hassle or fuss. I fixed my blinker cruise issue and it was super easy to install. Thanks etrailer!

Installed easily within the time frame suggested.
Works great to hold my bike rack and tow a small trailer.
The wiring harness was easy to install and instructions were great.

I’ve ordered wiring and a hitch off of etrailer and I have nothing to say but great things. Spent a long time looking for a hitch for my car and I was happy to finally find one that bolted on within 20 minutes and couldn’t have been easier to order.

Easy to install and shipped quickly! Only disappointing thing is it disables your driver side reverse light if you connect it to the harness. I left it unplugged since my trailer doesn’t have reverse lights.

by: Mike B 10/18/2022 One Year Later

The harness truly is plug and play, no splicing or cutting wires, lots of slack in the wiring loom to route it behind the trunk panel neatly and cleanly. It's worked without issue for nearly a year now. I'd recommend this product

by: Kurt 07/29/2018

I received this receiver about 5:00 PM only three days after ordering it. I called the customer and he delivered his car at 7:00 PM. I installed the the receiver, the taillight converter and wiring, called the customer back and He picked it up ready to tow his trailer by 8:15 PM. That is amazing. Flawless fit and function. That is how to satisfy a customer.

Instructions were clear; easy to install. Didn't need to drill a ground-wire connection and just used the one already there. Connectors were the right size and worked first time.

by: Bill G 06/10/2016

2010 Acura TSX

This did not fit my 2010 Acura TSX. 95% of it fit, but I did not have a plug for the right directional (the single green wire) on my car as the instructions said. So, I ended up tapping into the directional wire in the cars wiring harness (also green) with a quick splice wire tap. That worked fine, and only held me up a bit. I don't know what model car this one does fit, but it's not a 2010 Acura TSX.

Hitch and connector arrived in great shape.. Huge box.. thought you sent the wrong one.. It's frozen here in Ohio and I hav'nt installed it yet

Parts Needed to Flat Tow a 2006 Honda Accord Behind a Motor Home
Regular trailer wiring harnesses will not work in reverse. they are designed to fail if that is done to protect the vehicle wiring from damage if there were a short circuit on the trailer. You will need a kit specifically designed for flat towing. You can use a diode kit such as # 154-792-118158. You will also want to consult your vehicle owners manual on the proper procedure for towing the vehicle. If you need base plates on your 2006 Accord use # 1545-1 if it is not a Hybrid. For...

Class I Trailer Hitch Installation on 2007 Honda Accord Sedan
The Curt Class I hitch # C11327 is a confirmed fit on the 2007 Honda Accord Sedan. It also fits the 2-door Coupe for model years 2003 through 2007. It will require some drilling and minor heat shield modification. I have linked an installation video as well as a helpful article to aid your hitch installation. In this hitch you can use Class I accessories like a 2-bike rack such as # S64670 or a cargo carrier like # C18145. If you plan to tow you'll also need a wiring harness # C55502...

Is there a 2 Inch Hitch for a 2012 Honda Accord?
No, there is not. The only way to add a hitch to a 2012 Honda Accord is by installing one with a 1-1/4" receiver. I recommend the Curt Trailer Hitch item # C11085. This hitch is custom fit and bolts to your Honda with included hardware. It is a class I hitch with a 1-1/4" receiver. It fits both the sedan and coup models. I have linked an installation video below to help you get it set up. If you are planning on towing you will also need a wiring harness item # C55502 for the sedan or...

Correct Towing Products for a 2011 Honda Accord
The part 116813-56173-40001 can be broken down into a few different parts. The first 6 digits (116813) are the same as a Class I Curt trailer hitch and it will only fit a 2013 - 2017 Honda Accord. The next 5 digits, same as part # C56173, is a wiring harness that fits a 2013 - 2017 Honda Accord. And the last 5, same as part # C40001, is only a 1-7/8" hitch ball but it would fit the ball mount that comes with the trailer hitch mentioned above. If you have a Sedan or Coupe then the Curt...

Comparing Curt Trailer Wiring Harnesses for a 2008 Honda Accord LXP Sedan
For your 2008 Honda Accord sedan if it has LED tail lights then harness # C56175 is not recommended. Plus it is a hardwire harness that requires cutting and splicing into the vehicle tail light wiring. Harness # C55502 is a much better option. It will work with your Accord and just plugs in line with the vehicle tail light wiring.

Troubleshooting Wiring Harness Installation for a 2005 Honda Accord
First manually test the 4-Way on the Accord with a circuit tester like # PTW2993. Test each pin on the 4-Way individually, one at a time, while you have a buddy activate the corresponding function in the Accord. Make sure you get power at the appropriate pin and that you aren't getting power on the others. You will want to inspect the 4-Way itself for any debris or corrosion that might be built up around and inside the pins, cleaning out as needed. Also try and inspect any wiring that...

You can see the installation process in a 2006 Accord in the linked video. None of these wires needs to reach over to the passenger side which is sometimes the case with wiring for other vehicles. Each of the three connectors' wiring is approximately 15-inches long, plenty to make the necessary connection...

Curt Trailer Hitch for a 2010 Acura TSX Sedan
There seems to be some sort of mix up because trailer hitch # C11085 is designed to fit the 2011 to 2014 Acura TSX Sport Wagon, not the sedan. The proper hitch for a 2010 Acura TSX sedan is # C11496. And it does appear to stick out a bit as you can see in the video I have linked. If you plan on doing some towing the correct ball mount is # C45521. For a 1-7/8 inch ball use # 19256 and for a 2 inch ball use # 19258. For trailer wiring you can use # C55502.

Recommended Curt Class I Trailer Hitch Receiver for 2005 Honda Accord
You are correct in how the Curt Trailer Hitch Receiver -Class I - 1-1/4" # C11290 is mounted. This hitch has been tested to hold a maximum tongue weight of 200 lbs and a maximum trailer towing weight of 2,000 lbs when loaded. A riding lawn mower on a small trailer is probably at close to the maximum capacity of this hitch, so I recommend calculating the weights before doing this as your owners manual states 1000 lbs towing max and 100 lbs tongue weight. For your trailer wiring, I recommend...
