This harness installs inside the rear cargo area and plugs straight into the vehicle’s built-in wiring. There’s no drilling required—just one self-tapping screw to secure the ground. The plug-and-play setup means you don’t have to cut or splice wires, making it a tidy install that keeps everything hidden behind trim panels.
The Curt T-Connector gives you a standard 4-pole flat connector that powers your trailer’s running lights, turn signals, and brake lights. Each wire color is easy to follow—white for ground, brown for running lights, yellow for left turn/brake, and green for right turn/brake—so you can test and confirm every function with a simple circuit tester before heading out.
The integrated converter keeps the vehicle electronics safe from trailer-side shorts or overloads. It also helps prevent issues like blown fuses or back-feeding power. With proper grounding to a clean metal surface, the harness delivers steady power through each circuit so your trailer lights stay bright and consistent.
Instead of leaving the connector exposed to road spray or salt, this setup routes the 4-flat plug through the rear hatch when you need it. The weather seal around the hatch protects the wire even when closed, so you can keep the connector clean, dry, and ready for the next tow.

Bought this for our'11 CR-V and was able to install it without too much trouble. Getting behind the plastic interior panels was a hassle but that's the vehicle's fault. The job would be easier for someone with smaller hands but it went together well and works fine. I did not drill a hole in the body to run the wiring under the vehicle to the hitch, but left it inside the rear area and just route the wiring out the hatch opening when I need to plug in.
Shipping on time AWESOME
Installation video spot on...
This is my 4th purchase from Etrailer.com I would buy from them again.
Installation videos really helped during installation. They were a real selling point on purchasing through etrailer. It looks really good on the CR-V, in pictures, yet seeing it on the vehicle is even better. Thank you etrailer!

Every thing works good
Trailer hitch looks great on the car. We purchased a utility trailer last Saturday and we had no issues.
I finally installed the 'T-connector wiring kit' in my '09 CR-V. It went well, installed in about an hour following the clear instructions. Have not been able to test the install yet because I don't have a trailer, but I don't expect any problems - will contact you if I have. However, I still don't understand the 'T-connector ' description, there is no 'T' involved just a straight connector into the CR-V's wiring system.....Terry L!

Nothing to ad - still havent tested it!
I purchased the draw-tite hitch and the wire harness for my 2007 Honda CR-v. The items were shipped at no cost and what I ordered is what I received. The order was delivered on time and complete...absolutely no issues! I have ordered previously from etrailer and I have never been disappointed. etrailer prices beat another site and an auction site and included easy to follow instructions, this was a very easy installation which took less than an hour to install. I will continue to use etrailer as my choice for equipment and parts in the future. THANK YOU!!

One year later and I have no complaints. Works as advertised, very satisfied with my choice of product and etrailer. Thank you!
Easy to install and works perfectly.
Pulling the plastic sidewalls out in my new CRV had me a bit worried after watching the youtube vidio. The package included step by step directions including pictures. The instructional pictures were actually pictures of a CRV not a generic one size fits all vehicle. This wiring harness plugged in to an existing connection that Honda had pre wired and it looked exactly like the pictures. 15 minutes tops. It was so easy I had to double check to make sure I didn't miss anything. First time I've ever plugged in a harness, otherwise I was usually under the vehicle and cutting into wires and taping them.

I know I will have trailer lights every time I plug it in. Would recommend this product to my mother!
I installed this along with hitch # 24792 on my 2007 CR-V. The installation video was very helpful. The wiring works well. It's really nice to install a wiring harness that plugs right into the vehicle's connector without having to splice wires, etc. I would definitely buy this wiring harness (and the hitch) again. I use the wiring harness and hitch to pull a boat trailer with a 14 foot aluminum boat to go fishing.

After one year the wiring harness and the hitch work just fine. I would definitely buy this wiring harness and the hitch again.
Selecting the proper hitch for my car was very easy. The ordering process was straight forward. The order tracking kept me informed during the entire shipment. Before the product arrived I watched installation videos on YouTube. These made the installation trouble free. Once the products arrived it took me 1 hour to install the trailer hitch, and 45 minutes to install the wiring harness. Everyting is working just as I had hoped.

No problems to date. Everything is working just fine.
right part right on time thanks!!!!
I like the price (about 1/2 of Honda) of this hitch compared to other products. We have a very light kayak trailer to pull so the hitch construction does not appear to be vigorous enough for it's 1,000lb plus rating! It is clearly sufficient for pulling our fully loaded Kayak Trailer (with 3 kayaks and 2 bicycles) but total max weight is less than 350lbs.
I do NOT like the electrical connection dangling out from under our rear door!! This is ugly, prone to leaks into the cabin, causes door seal deterioration and very unprofessional install - looking. I used a 3/4 inch drill to put a hole in the bottom of our spare tire holder to route the electrical wiring and connector. The area is a thin steel structure and easily penetrated. To seal it, I put Duct Tape on the inside and outside then coated both sides with the black-tarry undercoat available at AutoZone. My mods, notwithstanding the original installation, cost about $15 plus my time.
This installation is in our 2010 Honda CRV and we have driven to FL and back (1,300 miles) with our trailer. It pulls very nicely ...but as may be expected, the CRV's gas mileage suffered. Also, on long or steep hills, the engine worked quite hard to overcome the additional drag (from the high profile) of the trailer and cargo. Although I extended the tongue by 4 feet (to clear the kayak) there is no tendency of trailer sway or bounce excessively and no hitch shifting or looseness.

No problems. My install mod still intact and tight, no leaks. You should consider a better trailer electrical plug install that does NOT hang out the back door seal
Simple installation. Just plug and play!
Very easy and quick installation with great video instructions!
Shipping was fast. Item was just as described and the video was very helpful. Our Honda Crv is now ready to pull our utility trailer.
No surprises & works like it is supposed to (except testing with a meter made me realize that DC is polarity sensitive....backwards it does not register, but correctly tested it does!) It's such a good feeling to do things for myself and save money w/o the hassle of schlepping my vehicle around to a fixer.
I ordered the wiring harness for my 2011 Honda CRV. The wiring harness was perfect, very easy to install, and works great! I am very pleased with this product.

Perfect fit. Easy install. Have been using for a year. Would recommend
I haven't installed the harness yet, maybe this week-end. I appreciate the quick delivery.
It plugged directly into my 2010 Honda CRV 8 pin vehicle connector. I decided to route the wires under the bumper cover like the Honda factory trailer harness for a cleaner install. I followed the Honda Trailer Hitch Kit P/N 08L92-SWA-101 installation instructions for removing the bumper cover and routing the wires. The only problem was I had to cut the wires about 6 " past the controller so I could pull the wires through the vehicle panel hole (the 4 pin trailer connector wouldn't fit through the hole). I just spliced them back together in the left rear cargo area opening (see pictures).
I’ve purchased a Hitch and wiring from etrailer.com for both of my cars and installed them myself. One being a Honda CR-V and the other a Mazda CX-9. If you are mechanically inclined it’s a breeze. etrailer.com also has video’s on their site for help of ease for installation. Also purchased the wiring kit for my Honda and installed that.
I’m in the process of ordering the wiring kit for my Mazda CX-9
Very good company for all your trailering needs.
Prices are competitive
Was total plug and play, other then shipping time all good!
Installation in my 2011 Honda CRV was a breeze thanks to the instructional video and easy to follow directions. Had the harness installed and was ready to tow in less than 30 minutes. Couldn't have been much easier!
Great video installation instructions. Easy install and works perfectly.

One year later the harness is working perfectly. It is very durable wire and the connections are as good as any of the stock connectors.
Think back over the last six months of how many times in your dealings of purchasing items that you needed and ,wanted in order to go about your life. How many of those interactions with companies and those “employees “ got it right one hundred percent? E Trailer is on target!you people have a good thing going! This review does not come flippantly. At 73 years I’ve had my share of life experience. So consider your job well done ??
