CURT Custom Fit Vehicle Wiring - C56336

  • Trailer Hitch Wiring
  • Custom Fit
  • 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.


Features:

  • 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
  • Includes a powered tail light converter that connects directly to your battery to avoid overloading your vehicle's electrical system
  • 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:
    • Stop/turn lights: 3 amps per circuit
    • 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.

Great kit that was pretty easy to install with the help of the install video on the website. The only thing that was some what of a pain was mounting the control box above where the muffler is but I managed. Finished install in about 2 hours or a little less from start to finish.

2017 Dodge Durango

Installed this harness on a 2017 Dodge Durango. I have had it installed for almost a year and it is still working as it should. Easy to follow instructions and only basic tools needed for install.



by:

Hitch fits good. New hitch does not have the tabs to fasten the lower bumper to the hitch. See pic. I guess you use zip ties. Not impressed



by:

Great product the fit was perfect and the hardware kit made the install easy

2022 Dodge Durango

Fit perfectly on my 2022 Durango GT. I didnt have to cut the bumper either. Highly recommend and easy install. Took me about an hour and a half from start to finish.

Got the wrong harness sent correct and delayed my installation a week, on track now

Installation wasn't fun but not bad, but the videos definitely help.

No issues. This was great fit for my 2023 Durango RT. Easy install and continues to do its job



by:

Very professional excellent phone call service. Assistant was highly informative that made sure all parts would match my vehicle.



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:

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:
2022 Dodge Durango

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 !!



by:
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:

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

  • 2023 Dodge Durango Trailer Hitch and 7-Way Wiring for Towing with a Prodigy P3 Brake Controller
    Hey Don, Here are the parts I recommend for a trailer hitch, 7-Way wiring, and getting your Prodigy P3 # 90195 set up on your 2023 Dodge Durango: - etrailer Trailer Hitch Receiver # e98901 - Curt T-Connector Vehicle Wiring Harness # C56336 - Universal Installation Kit # ETBC7 - Mounting Bracket # C83DR I really like the etrailer hitch because it has a more durable matte black finish, the Curt T-Connector gets you the 4-Way connector for basic trailer lighting, and then the Universal...

  • Curt vs. etrailer Trailer Hitch Receiver For 2023 Dodge Durango
    There is just a single difference between the Curt and etrailer trailer hitches that fit your 2023 Dodge Durango, which is the finish. The Curt has a glossier finish than the matte black finish of the etrailer hitch, so you can choose which you prefer. The hitches that fit your '23 Durango are the following part numbers: - etrailer Trailer Hitch Receiver # e98901 - Curt Trailer Hitch Receiver # C13182 The matte black finish is nice as it hides the inevitable dings, scuffs and scratches...

  • Recommended 4-Way and 7-Way Wiring for 2022 Dodge Durango
    In order to get a 7-way connection on your 2022 Dodge Durango you will need to start by adding a 4-way. I recommend the Tekonsha T-One Vehicle Wiring Harness # 118617. We have found the Tekonsha wiring harness to be the most reliable. This will plug into existing wiring and give you a 4-way for trailer signal lights. Once you have installed the 4-way, you will need the Universal Installation Kit # ETBC7. This kit comes with an adapter, wiring, and everything else you need to get your...

  • Trailer Hitch and Wiring Recommendations for a 2015 Dodge Durango
    I will be happy to compare the wiring harnesses for you. Tekonsha wiring harness # 118617 and Curt harness # C56336 both install and function the same way on your 2015 Dodge Durango. The Tekonsha harnesses have proven to be the most reliable but Curt recently redesigned theirs so I would say they are on par with each other. If it were me I would use the Tekonsha harness. I have linked a video showing an example installation for you. Hitch 87608 is actually a discontinued Hidden Hitch brand...

  • Does The Curt T-Connector C56336 Work With LED Tail Lights On 2021 Dodge Durango?
    It sure will! The Curt T-Connector Vehicle Wiring Harness # C56336 you were looking at is compatible with your 2021 Dodge Durango with LED tail lights. I included a video of the # C56336 being installed for you to take a look at.

  • 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.

  • Best Option for Trailer Wiring Harness on 2021 Dodge Durango
    The Curt Class III hitch, part # C13182 would be an excellent choice for your 2021 Dodge Durango. For a wiring harness, I'd recommend the Tekonsha # 118617 as they seem to be a bit more reliable in the long term compared to the Curt # C56336 harness. 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.

  • Is It Required to Run Power Wire for Curt T-Connector Vehicle Wiring Harness on 2019 Dodge Durango
    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...

  • 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,...

  • 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...

  • How to Install Prodigy P3 on a 2015 Dodge Durango Without Tow Package
    That is a bit confusing as to why Dodge would have the plug installed on your 2015 Durango for the Adapter # TK93VR if your model didn't come with the tow package. Since it didn't come with the tow package you need to hardwire everything. Basically just plug the Universal Wiring Kit # ETBC7 into your Curt T-Connector 56198 (replaced by part # C56336) and then route the wiring to your battery and cab for your Tekonsha Prodigy P3 # 90195 brake controller.

    The Curt trailer hitch # C13182 is listed as a fit for all models of the 2014 Dodge Durango so your Durango with the Rallye Package should not be a problem. I have linked the instructions and a video showing a typical isntallation for you. If you plan on doing some towing I also recommend etrailer ball mount kit # 989900.

    Yes, the Curt T-Connector # C56336 that you referenced is exactly what you want for your 2018 Dodge Durango without the tow package. If you don't already have a trailer hitch then I recommend going with the Curt Class III # C13182 which is easy to install and will allow you to keep your spare tire installed under the vehicle if it is the 18" size. To round out a towing package you also need a ball mount like the Curt # C45036. I recommend checking out the linked ball mount article to...

    In my opinion the Curt Hitch part # C13182 would be less visible than the Draw-Tite part # 75713. If you look at the picture I attached you will see that the Hidden Hitch has a more of the cross tube visible as well as the mounting brackets. The Curt only has the curved cross tube that comes down and is visible. For trailer wiring you would want the Curt Harness part # C56336.

  • Which Hitch and 7 Way Wiring Harness for a 2021 Dodge Durango GT
    I have a solution for you, but there is not a package with all of these parts offered so you'll need to get the individual parts. I'm also skeptical that there is room to fit a 7 way trailer plug in the opening left by removing the knockout panel; the 4 way fits without issue, but you'll likely need to find a mounting location below the bumper for the 7 way connector because of its' size. With that said, you can use the Draw-Tite # DT38MR and it will fit right behind the knockout panel,...

  • 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...

    We can help you install a 7-way on your 2021 Dodge Durango but since your vehicle did not come with the factory tow package you will need to start with a 4-way like the # C56336 which is a confirmed fit and then use a 7-way adapter like the part # 37185 if the trailer does not have trailer brakes or part # ETBC7. Then for a brake controller the Brake EVN # TK63VR would be a great option. Your trailer hitch from the 2017 Durango would also fit your 2021 like the part # e98901.

  • 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.
