CURT Custom Fit Vehicle Wiring - C56109

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • No 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 - no cutting, splicing or tapping required.


  • 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 - no cutting or splicing of wires
    • Locate connection points behind tail lights
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


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 installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.

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.

Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - C56109

Average Customer Rating:  4.7 out of 5 stars   (102 Customer Reviews)

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.


Harness is not suited for a Dodge Journey. No place to secure the power pack and it keeps coming down and pulling the wiring out. Also causes problems with the cars rear light system. Took it to dealer and decided not to pay the exorbitent price to have it secured permanently.

I have a 2018 Dodge Journey with LED lights so I needed the converter to hook it up. The Converter does not fit well in the light area and its very hard to keep in place. Need to make it smaller or have some kind of magnet or velcrow which would enable easier hook up.
William - 06/01/2022


Plug and play. Very simple installation of the harness by removing the taillight lens assemblies, pug it in between the veh harness and the light bulb socket and run the harness to the hitch. Takes only minutes. Make sure to get the wires connected to the correct side of the car.


Forgot to add the photos to my review

2020 Dodge Journey

One of the guides that allow the plug to go in straight is broken and the plug assembly wasn't even in the original package just thrown in a bigger box along with it. The hitch looks to be nice.

I will have our customer service team reach out to you.
-- Etrailer Expert Jenny N - 02/04/2022


I was very impressed with how easy it was to install this, the hardest part of the install was putting the rubber exhaust mounts back on, and even that was easy! I did it alone on a set of ramps and it only took me 30-45 minutes!

2015 Dodge Journey

I love the set up. Easy to install. Unfortunately I ordered the wrong part number needed for my car. Didn’t realize that a portion of tail rear lights are LED. So read carefully the description and make sure your part will fit.


It's working for over a year easy to install. Thank you very much!!!!


Did not fit my car. Trying to return it. Your email for return says it is going to charge me $XX to ship it back. Why it is a tiny package?

I will have our customer service team reach out to you.

2015 Dodge Journey

Great website when ordering and identifying the proper wiring harness for my specific vehicle. Good communication as to the status of my order and when it shipped. Product is as advertised and of high quality


I had NO Problems with this company, I will purchase products again.

2017 Dodge Journey

I spent close to $160 getting, what they said was, the wire harness for my vehicle from [rental trailer place]. After 2.5 hrs of trying to install, I read more online to find out it was incompatible. So I searched online and found etrailer harness that cost less than 25 including shipping. I installed it in about 30 minutes and it works great. A couple plugs and routing the wires was all it took. I will come back to etrailer for future trailer needs. Thank you.

2016 Dodge Journey

Easy install took about 10 mins to do everything. Perfect.


Super easy to install on my 2018 dodge journey!


This wiring setup is well-made. There is not enough emphasis on color codes. The easy way to remember right from left is to remember your L's - yellow left. Perhaps more emphasis needs to be made on keeping wires clear of areas such as the exhaust system.

This was a perfect wiring setup for my car. Easy to install. Works perfectly. Great product.

2013 Dodge Journey

Ordered a wiring harness and it arrived promptly. It was very easy to install with easy to follow instructions. Would definitely recommend this product to everyone.

Still works fine.
Darren C - 06/12/2019


Very easy to hook up worked great

2013 Dodge Journey

The trailer wiring for my 2013 Journey SE, fit perfect and was easy to install (once I figured out how to unplug the factory plugs, there are small tabs that need to be depressed before unplugging). Wiring length was good, connectors were high quality. This was way better than the old fashion method of cutting and splicing. Well worth the money to do it right. My journey was the 4 cyl with incandescent bulbs.

2010 Dodge Journey

The only thing I found wrong was the instruction sheet was incorrect. The way they are written the ground wire should have been on the drivers side, but was not, it was on the passenger side. Other than that it was great. When I bought this car brand new I had the Dodge dealer install a trailer hitch and wiring. They must had installed it wrong because it never worked right, and after awhile it did not work at all. Then the horn started blowing by itself, at all times of night. Now that I have removed that and installed this one the horn has stopped blowing by itself and my trailer lights work right.

2015 Dodge Journey

Worked well for the journey. I used the basic harness for incandescent bulbs. Easy to install.

Still working well. No problems with this setup.

2014 Dodge Journey

The installation instructions were good and the shipping notification and follow-up were excellent. Like other reviewers, I highly recommend

2015 Dodge Journey

Installed wiring harness on a 2015 Dodge Journey SE w/ halogen taillights. I chose this harness so I did not have to cut or splice any of the manufacturer's wires. The instructions were easy to follow and all connection were perfect. Installation took around 30 minutes

2015 Dodge Journey

Great product, simple straight forward installation, directions are spot on. Extremely better than trying to splice wires. The only thing to add is a piece of wire loom to run wipers thru so when wires are zip tied to hitch it looks like professionall installation.

2010 Dodge Journey

Great company I have ordered from them before products are always as stated and shipped fast and delivered ahead of the time promised. Today I installed the hitch and light kit I received in about a hour. Will continue to purchase from this company as needed.
Thanks to all at Etrailes

2013 Dodge Journey

Product was shipped quickly after order and on my door steps even before I was expecting it. With the help of the tutorial video, the product was extremely easy to install. Thanks!


Excellent wiring harness! Best method of wiring trailer lights I've ever seen!

  • The Drivers Side Taillights are Not Working on Trailer
    Sounds like you may have a grounding issue on the trailer side. However, a quick test will eliminate the vehicle or harness.

    The Curt T-Connector Vehicle Wiring Harness # C56109 you have is a fit for your 2010 Dodge Journey so you definitely have the right connector.

  • Where to Access 12V Power for Installing Curt T-Connector Vehicle Wiring Harness C56330
    Powered 4-pole harnesses like the Curt # C56330 are designed for a direct 12V connection to the vehicle battery in order to isolate the car's own internal wiring from any potential fault conditions on the trailer. Although it seems simple and is tempting to consider using the auxiliary 12V power outlet in a car, those outlets usually cannot deliver the same amount of current that a direct battery connection can. Alternate installation would likely void the warranty. Vehicles like your...

  • Recommended 4-Way Vehicle Wiring Harness for a 2016 Dodge Journey with LED or incandescent lighting
    The Curt T-Connector vehicle wiring harness # C56109 does not require a powered converter because it is designed for vehicles that have incandescent lights. Traditional incandescent bulbs draw much more power than modern LED lights, so they can handle the additional load from trailer lights. Vehicles with LED lights draw less power than those with incandescent lights. Factory installed LED wiring is not designed to handle the larger loads that will occur after hooking up your trailer...

  • Driver Side Tail Lights Shut Off After Trailer Wiring Harness Install on a 2018 Dodge Journey
    The most common issue we have with the Curt T-Connector Vehicle Wiring Harness part # C56109 on a 2018 Dodge Journey is an insufficient ground. Therefore, I recommend that you remove the ground for this harness, sand down the surface, and then reattach. This should fix your issue but if it does not then check the pins inside the driver side plug to make sure they are not bent or broken. If the issue still occurs after the ground has been reattached and the driver side plug has been checked...
