Wiring a trailer doesn’t have to mean cutting into factory wires. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector plugs directly into the existing wiring in the rear cargo area. It’s a true plug-and-play setup—no splicing, no tap connectors, and no guesswork. Once connected, it’s ready to send the correct running light, turn signal, and brake light signals straight to your trailer.
The harness stays tucked away inside the vehicle when not in use and can be routed through an existing grommet if you want it outside near the hitch. That means no dangling wires and no drilling unless you choose to. When you’re ready to tow, just pull out the 4-way flat connector and plug it in; when you’re done, stow it away again for a clean look.
This harness includes an integrated converter that matches your vehicle’s lighting system to your trailer’s two-wire setup. It takes in the stop, turn, and running light signals and converts them accurately for the trailer lights. The solid-state surface mount circuitry inside the converter ensures consistent power delivery to your trailer lights.
Whether your trailer uses LEDs or traditional bulbs, this harness handles both without modification. The 4-flat plug delivers the standard functions most small and mid-size trailers need—running lights, turn signals, and brake lights—so you can hook up confidently and hit the road right away.

Ratings & Reviews
I purchased the Curt wiring harness and Curt 2" trailer hitch for my 2005 Honda Pilot LX. The harness plugged right in to the vehicle once the rear trim panel was removed. Ran the wiring through a body plug and cable tied it to the hitch.
Great hitch! Easy to install and has held up great over the last year. I use it quite often to tow my 4 wheeler and tractor. Great price for a well made hitch. I would highly recommend to anyone looking for a great hitch.
Well done, no issues
Ordered my Curt trailer hitch on Nov. 16 and received it on Nov.18. A dealer wanted to charge me $360. plus tax for material and installation. . My cost for hitch and wiring $xxx. for my 2006 CR-V. Watched the videos and installed all of it by myself within an hour and a half.
Extremely satisfied with the service and the product. If I had not watched the videos I would not have tried it. Thank you Etrailer and Katie in customer service. I will use your service and recommend you to others.

Everything is working properly and if I ever need any similar products I’m sure I will purchase them from etrailer.
I ordered the Curt T Connector for my 2007 Honda Pilot so I could pull my boat and utility trailers around. The online ordering process was easy and it arrived on the date they said it would. etrailer also had a video on the installation process which made everything as easy as plug and go! Thank you etrailer for taking care of all of my trailering needs!
I bought the class 3 hitch and wiring harness for my 99 crv. I had watched the installation video before receiving the parts and it seemed pretty straightforward. When it arrived, I installed it during my lunch in 35 minutes and the fit and finish looks factory! The next day during lunch installed the wiring harness in about 20 minutes. It uses the factory connector and tucks away invisible untill you need it. I am THRILLED with the product and looking forward to using it. The car is rated for a 1000 lbs towing and the hitch is overkill, but I already had the 2" insert and ball and the price is the same as a lighter duty hitch. To me it seems the best deal on the market.

Thank you for your interest in my satisfaction! I find it hard to believe you can follow up on every purchase made online but I feel good that you are asking for my opinion.Let me assure you that I am completely, 100 satisfied with the Curt hitch and wiring harness that I bought. It was a piece of cake to install ok, Im a mechanic and it is probably stronger than the car I installed it on. I have pulled my trailer with complete confidence and am delighted in the products you offer.Thank you!
Installed in 15 mins, ran through the plastic seals to go underneath. Worked like a charm. Video was helpful.
Thank you for the fast shipping
Installation was fairly easy. Some panel removal was required, but that was the only difficult part. Took maybe an hour or so to install, test, and put everything back. Worked great for my occasional towing needs.
Installing the wire harness was super easy, and I've used it over the last year with great results.
Works great fits like a glove it's a great Plug and Play trailer wire harness for my 2003 honda element
Easy install following video. Plugged into existing wiring harness under panel near stow away.
Super easy installation! Works great!
The directions could have been a bit more. A vague photo to find the connector on a 2004 Honda pilot was really vague. I did figure it out and works fine but yea, could have gone much quicker with more detailed info.
The tow hitch receiver fits perfectly and looks great also intalled the wiring and its perfect
I am very pleased with the product and shiping was fast. Thanks a lot etrailer!!
Installing this hitch on my Pilot was SUPER easy. It took me less than an hour from the moment UPS dropped it off! Although it was recommended to lower the tailpipe, I was able to get the hitch in there without needing too. Thanks for the clear video on how to install the hitch and wiring harness.
This is a great item, it makes wiring for a trailer easy and avoids cutting an splicing wires. It's the only way to go!!! Your video only shows connecting the harness and leaving it in the storage area and just pulling it out of the hatch when needed. I prefer to have it mounted outside, with the access holes in the Honda Pilot this is an easy task. Also reusing the factory plugs using a soldering Iron to make a hole for the wire and a razor knife to cut a slit, with a little silicon caulk you get a great water tight seal
Thank you for the informative video instructions as well as helpful / honest reviews to research prior to making the purchase. I do not have anything to add that has not been covered in the reviews. Here is a recap of my experience that has been consistent with others.
1. Box was received with the driver side of the hitch pushed out. Only minor scratches which you can not see when installed and it did not impact the installation. Wrapping each end would probably be a good idea as stated in other reviews.
2. Removing 14 years of rust was the hardest part of the install (from the passenger side holes). Total time was approximately 1 hour as others have experienced. I used the bolts from the factory tie hook to work out the rust using 1/2" round wire brush attached to a cordless drill along with a full can of WD-40.
3. Installation of the hitch took about 30 minutes with assistance of a foot stool.
4. Plug-n-play electrical connector took about 10 minutes after watching the video.
5. Perfect fitment, fast delivery, easy website ordering experience and follow-up status notifications, and I can not be more pleased with the cost being under $200 for a DIY project.
I required this setup to tow a ~1,000 lb motorcycle trailer with a ~1,000 lb motorcycle next week and my Honda has a 3,500 lb towing capacity.
Thank you etrailer.com!
The connector works fine. Took me a little while to figure that out since my trailer apparently has some broken wires somewhere, but a little time turning lights on and off and probing the connector with a multi-meter let me figure out that it worked correctly and the problem was the trailer.
The install on the other hand sucked. The instructions were just plain wrong. Maybe they work for a Pilot or whatever it was based on, but it’s not even close for an Element. Fortunately, I found a YouTube video.
I had to take the rear passenger seat out and all the interior rear passenger side wall trim from C-pillar to tailgate to get to that stupid connector. It could have been accessed by just removing the right rear taillight if only you could grab it to pull it through a hole in the body panel, but I could not get any tool to hold it well enough to pull it through.
So Honda made it harder than necessary. It definitely should have been as easy as the instructions showed. They definitely should have put it in the same location as shown in the instructions. But they didn’t. It is significantly more time consuming than the instructions showed.

Connector is still working fine after a year. No issues. The install sucked, but I’m glad I installed it because being able to pull a trailer has been very handy with all the renovations we’re doing on our home.
Packages with care, fast shipping, and very clear instructions
Installed on a 2006 Honda CR-V. The Honda connector is taped to the wiring at the left taillight and is a relative pain to get to. The instruction sheet shows everything except the 12vdc outlet that has to be pulled out so the plastic cover can be moved aside. That outlet just press fits into the plastic, so pull straight out. When the converter was checked with an LED tester I noticed that the stop/turn LEDs dimmed when the taillights were on. So I built a "real" tester from 1157 bulbs, sockets, and a trailer side connector to match my trailer's system. It did not work at all!! Turns out this converter needs voltage higher than 12vdc to work, so with the car running at 14vdc it was fine. Turned the car off and tested as the voltage dropped back to 12vdc. Worked at first, then one side stopped, then the other. Makes me concerned with how this will work during the daytime when the Honda ELD keeps the alternator turned off. May have to drive with lights ON to make the ELD boost the voltage.
Quick shipping, item as described
Was Definitely Plug and play, works per fectly.
Fast shipping, great communication with updates, parts fit no problem
I installed the wiring harness, it went well. But there were no lights on my utility trailer, so I tried to figure out what was wrong, and well after a couple of hours, I found out it was the connector on the trailer itself. Replacing the connector on the trailer took care of that issue. As far as the Curt harness it is flawless!
