CURT Custom Fit Vehicle Wiring - C56336

  • 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.


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.

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

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.

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!

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

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

Excellent product. Fits like an OEM. Installation instructions were not very clear, but the product is wonderful.

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

I thought this would be a tedious install. Honestly routing the wires was the hardest part as I tried doing it at night. I went back out in the morning and 15 minutes later this was complete. The video for this item is very well done and shows you how to route the wire without hitting any hot spots.

id give 5 star but it bothers me running a power wire underneath the vechile to the battery up front always affraid it will rub n burn my suv to the ground i always put a plastic wire loom cover over the wire for overkill but ya works great 2021 dodge durango

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!

2019 Dodge Durango

I bought A trailer hitch and A wire harness. They were shipped together and when I received the shipment the box was torn and the wire harness was nowhere to be seen and I got in touch with etrailer and they replaced it with no problem at all. I have purchased things from them in the past and if the need arises in the future I will again.



by:
2016 Dodge Durango

I ordered the trailer hitch and wiring harness on Tuesday and totally surprised when it arrived Friday ( I took the free shipping option). I installed it to day (Saturday). The products were in perfect condition when they arrived. I installed by my self in 2.5 hours. The hitch went on in 20 minutes and the wiring harness took the remainder of the time. I am 60 and know if I did this when I was 20+ years younger, I have no doubt it would of took way less time.

All my lights work now exactly like they are supposed to. Thank you for your prompt service. I will definitely recommend etrailer to my friends.

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.

2015 Jeep Cherokee

Product thus far has performed as expected. Installation was easy with two notable issues. 1st- tucking the T-connector bundle behind the left turn signal assembly need positioning and 2nd the instructions should be clearer about routing the power wire forward up the passenger side to the fuse panel. The Durango/Grand Cherokee are tight on the underside and up thru the engine compartment..
Rickey was very helpful at etrailer with product correction.



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.

Works great, easy to install

  • 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 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...

    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.

  • 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...

If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900.

  • 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.

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.

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.

    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 # 19261 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.

For a hitch that fits your 2018 Dodge Durango I recommend the Draw-Tite Max-Frame Trailer Hitch Receiver # DT38MR. This is a Class IV hitch with a 2" receiver. It installs behind the rear bumper so it will be completely hidden with the bumper panel in place. If you plan on doing some towing, you can use the Curt T-Connector Vehicle Wiring Harness...

    Yes, the Curt # C13182 is a confirmed fit for the 2018 Dodge Durango. It is a class III hitch with a 5,000 lb towing capacity and 750 lb tongue weight capacity. If you are looking to tow and need to add a 4-flat the correct harness is # C56336; for a ball mount you would want # C45030 along with either 2" hitch ball # 63845 or 2-5/16" ball # 63847.

    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.
