You don’t have to cut into any factory wiring to get trailer lights working. The Curt T-Connector plugs into existing connections behind the trim panels on each side of the rear cargo area. Once the harness is in place, running one hot lead wire up to the battery powers the included converter, protecting the vehicle’s circuits while giving you a 4-way flat connector ready for towing.
Some vehicles can’t handle the extra draw from trailer lights, and splicing into those systems can blow fuses or damage wiring. This harness solves that with a powered converter that draws power directly from the battery instead. That setup keeps the vehicle’s wiring isolated and prevents shorts or overloads that can happen with direct-tap connections.
The 4-pole lead is long enough to reach a hitch-mounted bracket, but many users keep it coiled inside the cargo area when not in use. The foam weather stripping on the hatch seals around the wire without crushing it, keeping moisture, salt, and grime away. Storing the connector inside helps prevent corrosion and lighting issues down the road.
This harness sends clean power through its converter so it works with both incandescent and LED trailer lights. You get reliable running lights, turn signals, and brake functions every time you hook up—without worrying about flicker or compatibility problems that can show up on newer lighting setups.

E-trailer provided links to some very helpful you-tube videos. I strongly recommend watching those before you purchase or install. Then you'll know how much time you'll need and what tools you may need to purchase.
I installed this on my Nissan Rogue. It's a fairly involved process requiring removing several plastic panels in the trunk area and also crawling under the car to run a wire up to the engine compartment (to connect to the car battery). The kit comes complete with all the hardware you need -- wire ties, connectors, double-sided adhesive tape, etc.
All in all I am pleased with how the install went.
I have had this in my car for a year now. I haven’t used it a lot but what I was most worried about it it messing with the computer in the car. But there have been no issues at all. I like the fact that it used its own power from the battery and not just pulling extra load on the factory lighting wiring. Other than having to run a power wire through the vehicle (which is really the correct way to do it, just took some time), everything was plug and play and worked perfectly.
The wiring connectors were exactly right and it worked the first time. As usual with etrailer.
This was my third etrailer electrical kit install (having completed two Ford Escape kits earlier in the day).
The previous reviews and videos gave me a good idea on what to expect when I installed this on my wife's 2017 Nissan Rogue. By no means are these super easy, with the most difficult part being the auxiliary power wire that must run up to the engine compartment/ battery, but they work well and do not require any major modifications. The only thing I was not happy with was the fact that the plug end is located inside the trunk space and must just hang out the rear door seal when in use. Otherwise, it remains coiled up inside. Not ideal.
No problems with this installation. I ran the connector outside through a rubber drain plug in the floor for a neat, permanent install. Ran the positive wire to battery along the underside and through frame in places.

Still working fine.
This worked well for me. Had to install a hitch and light kit in a remote location to help daughter move, and everything worked well and installed as easily as possible. Very satisfied with purchase.

Still trucking down the road. Thanks for making it so easy!
The installation video was very helpful — I was able to install quickly and even pretty easily. The harness connectors fit my vehicle exactly as intended. One slight drawback: having the converter on the driver’s side makes it a little inconvenient to run 12v from the battery, as the easiest wiring path from the engine compartment is with the hydraulic lines on the passenger side.

1 year later - still working great.
Attempted to install like the last several curt harnesses I purchased for my vehicles. Typically you plug into the brakelights and run the cable down to the receiver. This particular design calls for extensive removal of the interior side panels to reach a harnesses that feeds the exterior light harnesses. Also, there is no available method to run the cable down to the receiver without cutting and splicing. The method that curts video showed was to allow it to hangout of the tailgate door. I did not install, ended up tossing it in a parts box since it was a couple of months before I could get-a-round to installing it.

This harness does store inside the cargo area until you are ready to use. Some people drill a hole in the trunk of their vehicle to fish the wire through then hardwire it back together with butt connections. If you attempt this be sure to use a grommet to keep fumes and the elements out of your vehicle. If you do not want to do that, here is the wiring harness that installs outside the vehicle: item # HM11143645.
Typically, I do not review products because I purchase them after researching and I know what I am buying. That being said, the trailer hitch and related items that I bought from etrailer came as expected. The real review is for etrailer. I searched for my trailer hitch and came across etrailer and watched the videos for my SUV, a 2014 Nissan Rogue. I watched several times and then made my purchase. The items arrived and went on the Rogue EXACTLY and as EASILY as was shown in the videos by etrailer. Everything was right on!! It was like having them there to give me a hand, sounds cheesy, but it's true. Should the need arise again for trailer parts, I will buy from etrailer. If anyone asks me where to go for trailer parts, I will send them to etrailer. This was a great experience. (say this with an Arnold Shwarzenegger accent) I'll be back!

Its great! Just used it yesterday, it is working exactly as it should be. Great product, great instructional video.
It’s not the easiest harness I’ve ever put in, but the instructions are good
Only the receiver has arrived waiting on the wiring harness
Product works as designed. Fast delivery and accurate manual. Thanks to Etrailer for the installation video and The best shopping experience.
Took a bit to install but works great
Good product. Written directions are generic but etrailer has a YouTube video for this exact product that helped me get it done. My biggest problem was not finding the right socket wrench in my tools

The harness was easy to install and works great after a year of being installed. I watched the installation guide and followed the details instructions that came with the kit. The install went very smooth I put a towing package on my wife’s Nissan Rogue. The ride is much more comfortable than my truck so she accompanies me much more often now. I haven’t had to worry about a thing. Just hook up and go.
Very satisfied with my experience, even before I purchased my hitch and wiring harness. The promptness of the shipping and delivery was first rate. I have ordered hitches in the past online from other vendors, and in those reviews, people mentioned how bad the packaging was. NOT SO with etrailer, packaging was superb!!!! And the online videos of both the hitch and wiring harness installation was terrific. Thank you for a terrific experience. Next time I am in need of anything related to this, etrailer is my first choice to go to!!!
I bought this as part of bulk order of a trailer hitch, electrical harness and adjustable ball & mount. Fitting the electrics was more involved than I had anticipated due to the amount of panels that needed to be removed from the rear of the Nissan Rogue but once I'd identified where the fixings were (two visible and two behind covers on each side) then it was straight forward. I didn't see the need to run a +ve lead for permanent connection to the battery since the lights aren't needed when the ignition isn't on so used a 10A fused plug into the the 15A fused accessory socket in the trunk. I'd be interested to know if there's a reason for running a lead to the battery which then increasing the drain on the battery while the car is not running. I dropped one star because the instructions for removing panels could have been a lot clearer and I spent quite some time working out how to remove them without breaking anything. Now that it's fitted, I'm more than happy with the result.

A powered taillight converter will draw its power from a direct connection to the vehicle battery, but will gain its switching information via its connection to the vehicles taillight harness or tow package connector. Years ago, taillight circuits in vehicles used higher gauge wire and had enough capacity to handle the draw of the vehicle taillights as well as those of a trailer. Now that the price of copper has gone through the roof and vehicle manufacturers try to save all the weight they can, the taillight circuits use smaller gauge wire that can handle the load from the vehicle taillights, but not much else. Drawing the power directly from the battery also serves to isolate the tow vehicles sensitive electronics from any short circuits that might occur in the trailer wiring. Connecting the converters power feed anywhere other than the battery or where the converters manufacturer recommends can leave your vehicles electrical system exposed to possible damage.
I have had two orders from ETrailer and feel confident purchasing from this company. From the good video's they have on Youtube on their products to good Delivery. My current order of the Curt T-Connector arrived as expected. Was packaged in Org. Manufacturer package. My next step is finding reasonable price for installer. I feel ETrailer offers good prices and do recommend this company with confidence.

Still in package. Funds delay my install and plan is have a Trailer Co. install for me. Feel I can do connections in rear but wire to battery cant do. Also want them to put on the panel for plug-in. I dont care to have plug hanging under bumper. In time hopefully will get a quote for its install.
Great product and easy to install by watching video. I am a return customer and have been pleased with the products and customer service. thank you!!

You're very welcome James, I'm happy we could help! What are you planning on towing?
The products I ordered are below. Generally speaking they were all great. Especially the hitch and ball. The wiring harness was a pain to install, but it works great. Not exactly sure why it needs to be wired directly to the battery, but that might be my own knowledge limitation. The flat connector mounting bracket could have clearer instructions. This is why I gave 4 stars and not 5. I accidentally bent it while installing, which caused some of the protective covering to flake off. Now some surface rust has appeared that I’ll need to take care of. The wire loom was not really practical for the underside installation except for a small section to the connector mount. I probably would get much less next time or none at all. Also don’t install that stuff in the cold weather. It became VERY stiff.
