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 tail lights. You will have to remove the tail light assemblies and some interior paneling to access this harness. 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. Once installation in complete, the 4-way connector will be stowed in an out-of-the-way location within your trunk.


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.


Powered Tail Light Converter with Surface-Mount Technology

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.


Curt SMT Circuit Boards

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.

2023 Nissan Rogue

This is my second Nissan Rogue install. The first was a 2011, for which I already had a power cable for an amplifier that I wasn't using any more. I really prefer an inside install vs running everything outside. On this 2023 Rogue I jacked up the left front, removed the wheel, then popped all the plugs holding the fender, plus a couple of screws on the little mud flaps. I used the hole for the hood release cable to get the power cable inside. It is well protected by the fender so I'm not worried about water ingress. It feeds in behind the far left of the dash behind the fuses and was easy to pull through. I then ran it along both door foot step trim pieces and through the corner of the back seat into the spare tire area. For the light wiring I used the grommet on each side where the tail light harness passes through the body. I used heavy waterproof electrical tape to re-wrap each grommet to seal out water. The green wire with the passenger side connectors was plenty long enough keeping the control box inside by the spare tire. My last step was to insert the fuse in the red battery connector after everything was connected and buttoned up. Attached my trailer lights and everything was perfect!

Very satisfied with each hitch/light kit I have purchased from etrailer.

2022 Nissan Rogue

The wire to the right taillight is too short. There is absolutely no way for it to reach. Luckily there is extra wire from the wire that runs to the battery for the splice. Other than this the installation was fairly easy with the pictures on line. The papers that come with the harness have black and white photos that are too dark to make out.

Regarding the instructions, I wonder if you would fine the pdf easier to read. Its located at the end of all the product information. Regarding the length of the wires, I asked the manufacturer, and you arent the only one having this issue based on other reviews. The manufacturer said to be sure to route the wire on top of the bumper beam. If you go under the bumper beam, it can use up a lot more wire length and cause it to be too short.

Green wire to short on wiring harness …easy fix. Fished in most of wiring, just a few tywraps, no clips needed…

Arrived 2 days early. This came shipped in several layers of plastic wrap along with the light kit, cap and small bracket. It was delivered with no damage or scratches. It was fairly easy to install with the help of my son and a floor jack. we'll do the light kit installation another day. Everything lined up perfectly. We did remove the to plastic pins to make it easier to flex the plastic bumper. trim out of the way. I would recommend it.



by:

This harness works great. Plugs are perfect and instructions fair. The green wire that goes to the passenger side tail light is too short and must be spliced. Seems crazy you have to do this but there's no way around it. It's a fairly involved project but better than risking cutting a modern wiring system. Route the power wire through the cabin to the fuse box. Trying to peirce the fire wall and access the battery is way too much work and likely will damage something.



by:

This kit worked fine for my 2023 rogue sv. However. The wire running between the driver and passenger side taillights is too short and needs extended. This is also an issue with the uhaul kit. Just seems counterintuitive to have to extend a wire on a vehicle specific kit.

You guys have known about the green wire being to short for 2 years I am not finished with this by a long shot



by:

Looked everywhere for a 4 pin wire harness for my 2021 Nissan Rouge. Perfect fit, easy install took less than an hour fit to finish. Photos shows T-connectors separated and connected. Power was an easy run to the battery and ground was simply to chassis. I pulled the 4pin tail to the receiver… done! … First time installing any type of trailer wiring harness.

It would be really helpful if you had a video actually showing the installation on a Nissan Rogue. Also, many people have complained that the green wire is not long enough to reach the car battery under the hood. This has been a complaint for years, so why is this not rectified? Or why is it not able to be wired in the back like other wiring kits?

I agree, a video would be helpful. As for the green wire, the manufacturer wants you to route the wire exactly as the instructions say to without deviation so it should be the perfect length per the instructions.



by:

Easy to install and works perfectly. Directions were easy to follow.

Nissan Rogue

The wiring from the box to the right side tail light is a little short for a 2021 Rogue. You have to cut the wires and add to it. Other than that it's really awesome.



by:

Not enough wiring to reach from one side to the other

The wire bundle was removed from my 2017 Roque to my 2021 Roque and worked flawlessly.



by:

Worked very well.. Some fishing of wires needed, but not hard, from tail lights to underside of rear



by:
2021 Nissan Rogue

The cable harness did not install as it was stated "It will fit" your vehicle. The right turn signal did not work, also the green lead wire was about 3 feet too short to connect to right tail lamp. The lamp connector lead wires were too short.
All in all a poor execution.

I apologize for the trouble you are having installing. This is a confirmed fit for your vehicle from the manufacturer. You do have to install exactly as it says, taking the simplest route, so that all wires fit.

Funny, Nissan dealer said there wasnt any wiring harness available yet (new Rogue) but you guys had one. Thanks. .

I am employed at a local hitch installer, and we regularly order from etrailer. They're inventory is outstanding, as is their customer service and product offerings! From the do-it-yourselfer, to the professional hitch installer, etrailer is an outstanding resource!



by:

Quality is awesome, only thing is the ups handlers messing up the box and losing the hardware and the installation guide



by:

Had to add a little bit of wire on right side to fit for length but otherwise it was easy to put on and worked great

  • Does Black Power Wire Of Curt T-Connector C44ER For 2021 Nissan Rouge Have To Be Run To The Battery?
    While it is definitely more work, the black 12v power wire of the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C44ER needs its own dedicated circuit and will need to be run to the positive terminal of the battery on your 2021 Nissan Rogue with the included in-line fuse. Not doing so will void the warranty of the harness, as there are no pre-run dedicated circuits on your Rouge. Instead of tearing into the interior of your Rouge I recommend running the...

  • Do I Have To Extend The Wiring On The Curt 4-Way Harness To Install on a 2023 Nissan Rogue?
    You will not have to extend any of the wires on your 2023 Nissan Rogue to install the Curt 4-Way # C44ER. This kit connects in line of the factory tail light wiring and includes a separate wire to connect to the vehicle battery to prevent excess power draw on the factory wiring. I have seen some reviews where they did extend the wiring which was most likely done as they chose to route the wiring a different way to make installation easier.

    You are correct that to install the Curt trailer wiring harness # C44ER on your 2021 Nissan Rogue you do not have to take the interior trim completely out.
