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.

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.

The kit was exactly what I needed to help add a towing package to my Durango. The videos on etrailer.com were perfection to help when it came time to install it. Unfortunately (and through no fault of etrailer.com) I traded the Durango in on one with a v8 about 3 weeks after I installed the kit. So, I cant say how it's doing now lol

I think run a power wire is a little unnecessary. When you can buy one that are not plug and pay that don't require a power wire

There are a couple of good benefits of having the taillight converter being directly connected to the vehicle's battery. For one, it helps keep the tow vehicle's wiring system isolated from the wiring on the trailer. If a short circuit happens in the trailer wiring, the harness/converter will prevent the vehicle's wiring from being damaged. Secondly, the taillight wiring harnesses of most never vehicles aren't capable of handling the power requirements of both the vehicle and the trailer taillights. A direct power draw from the vehicle battery is very necessary. I hope that helps explain it for you....



by:

Worked good and can on time. The only thing was the right side wiring could be longer for better mounting of the black controller box.

Shipping was fast. I have not had a chance to install the hitch yet but plan to this weekend. The videos for each item were very informative and easy to follow. Knowing what tools I may need ahead of time is great and I have not doubt that the install will be smooth. Thank you!

I know you probably haven't installed it yet, but we would love to know what you think once you have, too :)

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

Great place. Super fast shipping! definitely recommend and I will definitely do future business with them



by:

amazing website, easy to use and navigate, part install was great and love the videos as well thank you



by:

The control box wiring was not nearly long enough. Had to reach way up into vehicle to try to attach. Finally able to zip-tie it to other wires. Not ideal and made the installation take twice as long as it should have.



by:
2016 Dodge Durango

Very nice fit. In my opinion, it wasn't too bad too install. I had the most trouble getting the original bolts out of the bumper iron than any other part of the fitment. I chose to do the Curt wiring harness at the same time....THAT took longer than the hitch installation. The back end went smoothly, it is the routing of the positive wire to the battery that is the time consumer. That is if you choose to do it in a neat and thoughtful manner. Overall, both projects took about 5.5 hours for me to do all by myself. Probably shouldn't take as long, but with the trouble with the bolts.... good products, I would recommend them to anyone.

Super quick delivery and the package was in great condition upon arrival. Very pleased with Etrailer and I will order from them if necessary.

Excellent service and very fast shipping and delivery



by:
2019 Dodge Durango

The install video wasn't very helpful in routing the positive wire to the battery or where to selftap the ground wire. After viewing videos on youtube i discovered uhaul says to selftap the ground wire into anywhere behind the passenger tail light. I routed the positive wire along the gas lines thru the control arm brackets and then along the wire harness long the passenger side to just behind the front wheel, i went up thru a hole in the fire wall and connected to where you would jump the car. Still tbd if it works properly, as i just installed it to the car, but haven't used it on a trailer yet.



by:

Very well designed. Made install Very simple and easy. These kind of products keep people coming back!

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

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.

everything arrived on time my entire order is in the box all parts and pieces. now I just have to install it.



by:

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



by:

Instructions were clear. This was a much more complicated install than the method I previously used (splicing into twilight wires and hoping i picked the right ones), but I'm much more confident in this install and the materials all seam to be high quality.

  • Recommended 4-Way Wiring Harness for a 2021 Dodge Durango w/out the Tow Package
    Hey David! If you're just wanting to run the lights on that 7-way all you will need is a 4-way harness and a 7-way adapter. This will be a whole lot easier then running the wiring for a 7-way, for functions you have no intention on using. To add a 4-way connector to your 2021 Dodge Durango RT, you will want the Curt T-Connector Vehicle Wiring Harness item # C56336. This custom-fit T-connector plugs into your Durango's wiring harness, which is located behind the tail lights. I have linked...

  • Recommended Hitch for a 2025 Dodge Durango
    Congrats on the new SUV. Does the 2025 Dodge Durango GT have the bumper cutout on it for the factory hitch? If so the best one for your Durango is going to be the Draw-Tite item # DT38MR. This hitch installs behind your rear bumper and is pretty similar to the factory one. The only difficulty you'll encounter installing this hitch is removing the rear bumper cover. If your Durango does not have the bumper cutout, I recommend our etrailer Hitch item # e98901. This hitch attaches to your...

  • Does the Blue Ox Hitch BLU53UR Interfere w/ the Spare Tire on a 2020 Dodge Durango?
    Only if you have a spare larger than the 18" one. The Blue Ox Trailer Hitch item # BLU53UR, like all the other hitches for the 2020 Dodge Durango will only accommodate the 18" spare. If you have the larger full size one you won't be able to mount it back underneath your SUV when you install a hitch. The Blue Ox Trailer Hitch item # BLU53UR has been confirmed to fit the 2020 Dodge Durango. This hitch is custom fit and bolts to your SUV with included hardware. It is a class III hitch with...

  • Wiring Kit for a 2024 Dodge Durango
    Hey Jim, thanks for reaching out! I see you purchased the curt T-Connector # C56336 to pair with your etrailer Trailer Hitch Receiver # e98901. This will work out great for you, and I'm glad to see you also got the Mounting Brackets # 18144 and # 18136 to keep the 4-Way located next to your hitch receiver. Do you plan on installing the hitch and wiring on your own, or are you looking to have a shop do the install?

  • Can Power for Curt T-Connector and Universal Wiring be Used on Same Wire for a 2020 Dodge Durango
    Hey Andy, thanks for reaching out! The power wire for the # ETBC7 wiring will need to be separate from the Curt T-Connector # C56336. If not, this circuit could get overloaded, and then you'll be stuck without lights as well as brakes. You can run the wiring along the same route, but they need their own connection to the battery. The Curt Echo # C51180 will be a great addition to this setup as well! Do you have any other questions about the installation?

  • 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...

  • 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.

    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 kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your vehicle with an included bracket.

    I checked the owners manual of your 2015 Dodge Durango V6 and the towing capacities depend on the transmission style.

  • 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.

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.

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,...
