  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • CURT

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.

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery

  • Constructed using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:

    • Tail lights: 6 amps per circuit
  • 1-Year limited warranty


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 to access this harness. Once you've plugged in the T-connector, run the hot lead 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 is complete, the 4-way connector will be stowed in an out-of-the-way location within your rear cargo area.


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.


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.

Everything fit perfectly, installation videos were a huge help.
If I had one thing to complain about it would be the packaging that this hitch came in, could be packaged a little better, my box had holes and rips in it, luckily all pieces were still inside, other than that , would definitely order from here again !!

2020 Dodge Durango

Just finished installing this morning. Read the instructions and watched the video. Those were very helpful. Although the vehicle in the video was the same as mine, 2020 Dodge Durango GT, some of the features on that vehicle were different. I did not have to lower the spare tire or the exhaust. Everything was accessible without doing so. Also did not have to trim the bumper facia. The wiring harness hooked up just as well. Instead of running the wiring on the outside of the tow hitch, I ran the wires to the left side of the vehicle through the hitch bar itself. Also was able to mount the controller up much higher and future away from the exhaust. Figured I would install the wiring harness at the same time as the hitch. Took a total of 3 hours to complete.

Product is great. Not a single problem after over a year. I installed the 7500lb hitch with the above wiring harness. Figured to go a little over max tow capacity to ensure a great towing experience.



by:

Wiring harness worked well and was easily installed.



by:

Good product with everything you need, but the install videos are the deal sealer! Love eTrailer, without the how-to videos, it'd be a lot more difficult.



by:

Installed on 2016 Durango, it went well, nice product, I really liked the positive wire gauge, and quality! I added a small mounting bracket to an existing 13mm stud to mount the controller for a solid mount location. Thank you



by:

Excellent plug and play..installed it when doing the hitch to make it so much easier



by:
2018 Dodge Durango

Fit my 2018 Dodge Durango perfectly! Easy installation and solid design. I ended up trading i nthe Durango shortly after so no experience towing but for fit it worked beautifully



by:

Nice Hitch and comes with everything you need to complete a easy installation and a perfect fit great product.



by:

Received my trailer wire harness on a Sunday USPS priority delivery. Product had clear directions and I installed it on my own in 1.5 hours. Thanks ETrailer for the fast shipping. Love your website and coustomer service. Thanks Kevin



by: 07/26/2021

Loved the installation of this. So easy, took me 30 minutes from start to finish. Includes everything you need. I used the installation video they send you in your purchase email instead of the paper. Clean install, works great so far. Highly recommend



by:
2022 Dodge Durango

The kit was new in box but old stock. The 2 sided tape was not sticky anymore. The butt connectors and ring terminal were all oversized for the wiring which would cause improper and unsecured connections. Grounding wire needed to be about 2" longer to reach an existing bolt to prevent drilling. System works good once installed just poorly executed and would have been nice had it come with usable mounting tape.



by:
2020 Dodge Durango

It would be nice if the cables from the passenger side tail light were just a bit longer to allow for better mounting options. Otherwise, this is a simple install and works nicely. Good instructions and all needed hardware is included.



by:

Very easy to install. Zip-ties are included but you will need more. Check with your dealer/service manager before installing.



by:

Nice trailer hitch. Fast delivery .



by:

Well unit works. The Hoppkins unit which was like 5 months old did not.

One thing to note is every other one I have installed runs the power wire down the drivers side to the unit. This means the green wire to the right rear directional is long to reach.

I reused the power wire from the Hoppkins which was on the drivers side but now the green wire is too short and the yellow and brown for the left side was really long.

No biggie just made the green wire longer snd coiled the yellow/brown and secured it. Just be aware of this. If installing the first time just run the power wire down the pass side and you are hood to go.



by:
Dodge Durango

Generally not that difficult to install on my Dodge Durango. It helps to first watch the how to video on the etrailer web site and give yourself at least a couple of hours to do the work. There was just enough length from the right side tail light connectors to the power module. So - It's important to make sure the right side connections are securely done BEFORE anchoring the power module with the adhesive. Everything else is pretty clearly explained in the video. The overall quality of the parts seems OK.



by:
2018 Dodge Durango

Great product. Easy to Install, not done yet on the Durango but I installed one just like it on my Nitro. Easy install check out e trailers videos for step by step instructions!

Arrived ahead of schedule



by:
2014 Dodge Durango

etrailer.com services were as expected and I had no issue with them 5 stars. Installation of the trailer hitch was easy and only took an actual 30 minutes once you had the tools. The wiring for the 2014 Dodge Durango to support the hitch was ok but the dodge 2014 battery location is under the passenger set so the directions could use some additional details.

My only issue was that when we opened the box from e-trailer and removed the hardware that was taped into the trailer hitch tubing a bunch of rodent poop, dried up fell out and all over. So not so cool.

Otherwise all was fine.



by:
2015 Dodge Durango

I ordered the Draw Tite hitch for my 2015 Durango and the installation could not have been easier, less than 30 minutes! I also ordered a wiring harness to go along with it and as I was watching the installation video I realized I had gotten the wrong one because my vehicle came with a trailer tow prep package from the factory. I immediately called etrailer and let them know. They sent me out the correct harness and sent me the shipping label to return the other. Within 4 days I had the correct harness installed and all is good. Absolutely fantastic customer service, the way all businesses should be run. Will be recommending you to all my friends. Thanks!



by:

Took little bit to route



by:

Great fit and easy to install. Was able to install the stock hitch cover which is exactly what I wanted.



by:

This product failed in about the 9 month time frame. My Drives taillight stayed on with the car turned off and I had to disconnect the taillight adapter and remove the harness to prevent my battery from draining.



by:

It was easy to install and works great. The instructions were easy to follow as well.

  • Does 2018 Dodge Durango Need to be Flashed After Installing Curt T-Connector Wiring Harness
    The Curt T-Connector Vehicle Wiring Harness # C56336 that you referenced is designed for your 2018 Dodge Durango if it did not come with the factory tow package, but it can certainly still be installed and used on your Durango if it does have the factory tow package and wiring. Because the harness will simply connect in line with the vehicle's tail light circuits (and not with any of the factory tow package wiring) there is no need to have the computer flashed. This will work great as soon...

  • Recommended Vehicle Wiring Harness for 2014 Dodge Durango without Factory Tow Package
    The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56336 you referenced in your question is a great harness and is what I recommend for your 2014 Dodge Durango. The T-connector will plug directly into existing wiring behind the vehicle tail lights and will provide a 4-way flat trailer connector to power your trailer's signal lights. Because you are just plugging into the tail lights behind your vehicle, you should not need to have the computer reset or flashed...

  • Does Curt Trailer Wiring Harness for 2014 Dodge Durango Have to Run to Battery
    When installing trailer wiring on your 2014 Dodge Durango like with the Curt harness part # C56336 you do need to run a power wire up to the vehicle battery. There isn't a power circuit at the rear of your vehicle you can use in place of this connection. The reason is this circuit is what powers the taillights of your trailer, and if there was a short on the trailer wiring it wouldn't damage the vehicle wiring since it draws straight from the battery instead.

  • Best 4-Pole Trailer Wiring For 2018 Dodge Durango Without Factory Wiring
    Great question Fred. I recommend to use the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat part # 118617 for the 2018 Dodge Durango without a factory wiring package. The Tekonsha can handle over 1 more amp per circuit of power compared to the Curt wiring harness part # C56336 so you don't overload the vehicle's electrical system. The Tekonsha converters are also known to last longer compared to the other brands. Although both wiring harnesses will work for the 2018 Dodge Durango,...

Installation will be nearly identical on your 2014. For a plug-in trailer wiring harness for your 2014 Durango you can use # C56336.

This connection powers the trailer lights and adds another level of circuit protection between...

  • Troubleshooting Trailer Wiring Harness Thats Only Putting Out 4-Volts on Running Light Circuit
    As a first step, you'll want to use your multimeter and check the voltage entering the black converter box on the input side to make sure there's 12-volts going in while the running lights are switched on. If you have the correct voltage entering, but not leaving the converter, then the converter bad and the wiring harness would need to be replaced. The most likely cause of this is a short in the running light circuit on the trailer. Before installing a new trailer wiring harness, you'll...

    It is required to run a power wire from the Curt T-Connector Vehicle Wiring Harness part # C56336 to the battery on a 2019 Dodge Durango. The power wire is actually what provides power to the lights on the trailer. The tee connectors simply obtain the signal. The vehicle's factory tail light circuits are not rated for the extra power needed for trailer tail lights so you'll need to pull power from the battery for these. It's really not that big of a deal to run the power wire, just follow...

  • How Long Does Trailer Hitch For 2017 Dodge Durango Citadel Take
    The Curt hitch part # C13182 that you referenced is a confirmed fit for your 2017 Dodge Durango Citadel. Install should only take about 30 minutes for a shop who knows what they are doing so half their hourly rate would be right. $250 would be waaaaaay too much, but maybe the Dodge hitch is much harder to install. For trailer wiring you then would want the part # C56336 which is a confirmed fit for your vehicle that does not have the tow package. If you wanted to do some towing you might...

  • 2014 Dodge Durango Tail Lights Stay Lit with Curt Trailer Wiring Harness Installed
    The vehicle tail lights should not be lighting up with trailer wiring harness # C56336 installed on a 2014 Dodge Durango. That indicates that there is a short or power is somehow back feeding through the converter. I recommend replacing the wiring harness with # 118617 since we hear about less issues with the Tekonsha/Tow Ready wiring harnesses. I have linked a video showing how it installs for you.

For a ball mount, I'd recommend part # 2753 and # 19260 for a 1-7/8 or # 63845 for a 2 inch trailer ball. I've linked to installation videos for the hitch and wiring I recommended.
