This harness ties right into the existing junction box in the cargo area, using the same factory location designed for trailer wiring. There’s no need to cut or splice a single wire. You just plug the connectors in, and everything fits together solidly behind the trim for a clean install that looks like it came that way from the start.
The built-in powered converter takes the load off your factory wiring and shields the vehicle’s electronics. It uses Curt’s newer circuit board design that sheds less heat and lasts longer than older styles. That means your lighting signals stay consistent and your vehicle wiring stays safe, even when towing frequently.
With a standard 4-flat connector, this harness gives you running lights, turn signals, and brake lights—everything needed for most small and mid-size trailers. It’s simple, universal on the trailer side, and easy to test with a basic circuit tester before hooking up.
Each connector seats firmly in place to keep out dirt and moisture. The ground wire mounts to clean bare metal for a solid connection that helps prevent flickering or intermittent signals down the road. Once installed, it’s dependable trip after trip with no extra maintenance needed beyond basic checks before towing.

I know what good customer service looks and feels like ... and the folks at etrailer.com have some of the best customer service I've ever seen. Pretty awesome company and I appreciate everything they did to get me my trailer hitch and wiring in the time frame I needed it and for their constant and timely communications. They delivered as promised, and left me 100% satisfied and happy! HIGHLY RECOMMENDED!!
I purchased a trailer hitch for my 2010 Honda Odyssey. The installation to include the wiring was simple from start to finish. The product matched my vehicle perfectly. I highly recommend etrailer especially considering their low low prices.
Good quality equipment and materials. Instructions clear and described exactly what I found on my vehicle, therefore installation went very smoothly.
Worked perfectly with my trailer.
It was easy to install and I liked how it could be tucked away. For the first couple months it worked fine. Although now it no longer works properly,, I am not sure of the cause. It may have nothing to do with the quality of the kit. If I find that the kit can be replaced and it wasn't the cause I would then give it a higher rating. I didn't see any explanation for the problem which is the the brake power stays on and the right blinker side doesn't work at all. I already had the trailer checked to be sure it wasn't the problem and it works fine on a battery. I am still testing the vehicle side but vehicle lights all work fine.
I purchased this for our 2006 Honda Odyssey. Installation was straightforward using the video that shows how to it do it on a 2010 Odyssey. Very happy with my purchase.

Still working well!
Incredibly easy to install, with the instructions it took me less than 10 minutes. The 4 pin connecter that goes to the trailer has enough wire that I was able to run it through the inside of the panels and keep the connecter inside the van when I am not using it keeping it from the weather and corrosion. I originally bought it so I could rent a uhaul trailer and the wire is long enough that I didn't need an extension to the 4 pin for the lights.
This is the second harness I put in my Honda Odyssey. The instructions are clear and etrailets install video made this about a 15 minute job. My lights all work again and I'm a happy camper.

All is well, your products have never disappointed!
I have a 2005 Odessey, this wiring harness was simple and made with high quality parts. I watched the install video and made it extremely easy to install. I called the Honda Dealership prior to seeing this item and there price was 4x higher and would take a week to get. I ordered this part and it was delivered in 2 business days.
Very Pleased with etrailer.com Thank you!

Still working great
I installed this wiring harness to my 2009 Honda Odyssey. The Curt wiring harness is quality built, a great price and very easy to install. The video was extremely helpful for visual learners like myself. The shipping was fast and the service from etrailer was exceptional.

Still works like it should. In fact I just moved from Fort Hood to Las Vegas and pulled my bike trailer with no issues in the wiring or signaling. I appreciate the follow-up.
Fit perfectly, easy to install
It works great very easy to install
I just love it . The hitch and wiring system took a little more than an hour to install . It looks great too ! I can't wait to use it . Thank you
Wiring package was easy to install and use. Etrailer staff were quick to respond and very helpful when I had questions. I would definitely use etrailer again in the future.
Fast shipping. Great product and easy i nstallation
Great service. Ashley was the Best. She went above and beyond. 100%
This is a great hitch! It's well made and bolted right onto my Honda Odyssey. I'm using my hitch to tow a small trailer for getting rid of yard debris. Now I don't have to go out and by a truck. This was very easy to install and it came with everything needed!
Looks great. All parts are there and install should go well.
I worked in the camper trailer business back 40-50 years ago. WOW!! What a difference. Basically plug and play. What a great way to wire a trailer. Neil

Still, after a year, whenever we use the trailer we know the lights will work. If there’s a problem it’s with the trailer lites. Great pirchase!
This was an easy to install product. I followed the instructions up to the placement of the end of the 4-pole connector. I routed mine into the bumper so I could leave a 7 pole connected to it more permanently.
Everything fit as it should pretty straight forward installation
Ordered it with hitch receiver. Delivered together, well packaged. Installation was simple. Followed video and everything went according to direction. Have not had opportunity to test it on trailer, but I'm confident it will work.
Called several times about a 99 Silverado that is a split year and NOONE at e trailer would help. They said it not made. Called a mom pop shop in platine and he knew the part number and shipped it to me. Thanks for NO HELP.
Well made and instructions were written east t
Worked as advertised. Fairly easy to install on the Honda Odyssey.
