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!

Absolutely perfect so far! I always check all my lights before I go with the trailer and it’s been great!

Nissan Rogue

I needed to make a trip across country in a hurry but replaced my pickup truck with a Nissan Rogue (w/o a trailer hitch). Working with etrailer we found the right hitch for my vehicle, I purchased it and had my repair shop install it all (hitch and wiring harness). the installation was accomplished easily (feedback from my shop) and I loaded down my trailer and towed it across country with ZERO issues. The etrailer folks really know their QUALITY products. If you are considering adding a hitch to your vehicle, please look them up, you cannot go wrong.
Thank you etrailer, you folks were a real lifesaver.



by:

This trailer wiring is a great help, but like most others the green wire for the right side is way too short. I knew this going in so I expected it. Still the manufacturer should correct it. I wired mine from the inside to keep it neat and tidy. More work, but worth it to me.



by:
2023 Nissan Rogue

I know I can give you a five star rating from previous experiences and videos supplied from your site. A few paint scratches from shipping but that is to be expected with such a heavy odd shape. A small gloss black paint stick will take care for that. A very easy installation. Should I thank Nissan or Etrailer for that.



by:
2023 Nissan Rogue

Package may have been opened previously as it was taped shut. Had to splice about 2 feet more to get the wiring to reach the right tail light. Installation of the wiring took a little bit longer than the hitch install. Once installed, the wiring worked perfectly.



by:

Connector harness worked perfectly. The green wire for the passenger side is about 24 inches short and had to splice in a piece. Not difficult to do.



by:

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



by:
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.



by:

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.

2021 Nissan Rogue

Kit is as per what we see in the video. Shipping was fast even to Canada.



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.



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.

Very good customer relations and fast service.

Thank you Carl Cole

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?

Etrailer Expert

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:
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.

well and are well made will buy again when needed

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

    I have another option for you, but the Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # HM11143584 you were looking at is designed to fit a 2013-2021 Nissan NV200 and will not fit your 2021 Nissan Rouge.

    It sure is! I reached out to my contact at Curt and the Curt T-Connector Wiring Harness # C44ER you were looking at is confirmed to fit all models of the 2021 Nissan Rogue. Since you will be towing with your Rogue you will also need a ball mount, hitch ball, and hitch pin and clip.

  • What Wiring is Needed For a LED Hitch Cover Light On a 2021 Nissan Rogue?
    A LED Brake Light Hitch Cover will fit into the etrailer Trailer Hitch Receiver # e93ZR you installed on your 2021 Nissan Rogue. The light needs to plug into a 4-way flat connector so you will also need the Curt T-Connector Vehicle Wiring Harness # C44ER to install on your Nissan Rogue. Hitch covers with a light like this will all use this style connector since the vehicle is most likely going to have trailer wiring with a trailer hitch receiver installed.

    To add a hitch for a bike rack to your 2024 Nissan Rogue, I recommend the etrailer item # e93ZR. This hitch is custom fit and bolts to your Nissan with included hardware. It is a class III hitch with a 2" receiver so it will work great with most bike racks on the market. It also has a 525 lbs maximum tongue weight so you will have plenty of capacity.

    For your 2021 Nissan Rogue AWD SL model we do have the Curt Class III hitch part # C24HR does hug closely to the lower rear bumper area. Since this hitch only has the hitch opening hanging below the rear bumper and hugs so closely there isn't a good place to mount a 4-way bracket like for the 4-way harness # C44ER that fits your vehicle. So your best option would be to mount the part # 18144 to your rear bumper instead. This also allows you to put the bracket in more places to make it...

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.
