Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.

Installation
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

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.
Only the receiver has arrived waiting on the wiring harness
It’s not the easiest harness I’ve ever put in, but the instructions are good
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.
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!!!
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.
It was al plug and play
hot wire over to back area power plug makes for such a clean install
video on line steps you right througt it
Everything fit, plugged in and operated successfully!
Plug and play simple
Great price. Having trouble getting it hooked up.
Product has worked perfectly since originally purchased. Easy installation and towing a trailer with all lights working. Definitely recommend this company and its products, they are the best!!
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.
I’ve ordered a hitch for my vehicle also and wiring. I was impressed with the quality and would recommend purchasing from etrailer.
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.

Bought for my 2014 Nissan Rogue fit perfect and went on easy..then bought 2017 Rogue transfered to new car and again fit perfect
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.

Have not had to use it, but no problem with the car tail lights. S: This was for a 2017 Rogue.
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.
Excellent product, received exactly what I ordered.
The wiring connectors were exactly right and it worked the first time. As usual with etrailer.

Working perfectly, etrailer folks are really helpful.
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.
I received the order yesterday and installed everything the same evening, Order was well packaged and the part fit as it should, Fairly easy install and the Curt wiring harness kit was plug and play. As a technician, I appreciate quality parts and a product that meets expectations. Thanks
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.
Very easy to install

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.
