CURT Custom Fit Vehicle Wiring - C56133

  • 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


  • Maximum amperage:
    • Stop/turn lights: 3 amps per circuit
    • Tail lights: 5 amps per circuit
  • 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.

2013 Dodge Durango

Very easy installation on a Dodge Durango 2013. Watching the install video on the site helped me install this in 20 minutes. Most of the time was spent deciding where to put the zip ties(keeping the cables away from exhaust). It works great. Cords is long enough to reach any installation situation. Using it for LED lights on a hitch carrier.

The product is still working great after 1 year. Just used it on a road trip and I was glad I had this installed since my camping gear blocked my Durangos lights. Make sure you pair these with LED lights.

2011 Dodge Durango

Awesome product and very easy to install. 30 min to install my new hitch and wiering kit.

The area behind the taillights is fairly well protected from the elements, but water will still splash up in there. Using some dielectric grease such as # 11755
Dielectric Grease for Electrical Connectors, 2 oz.
in the connection will do an excellent job of keeping moisture out.

On time and came as described works good for my 2012 Durango

2013 Dodge Durango

2013 Durango. Video was very helpful. Easy to install. Tow bar and wiring done in under 2 hours. Testing it tomorrow.

2013 Dodge Durango

Easy to install and it seems made of a good quality materials.


Very easy to install plugged directly in to factory connectors


I received my towing package today in a timely manner. Also ordering much of the electrical components for breaks among others.. I am very pleased with this product. Nicely built. Plan to use this hitch for towing a boat and 2 horse trailer. Living on a ranch it is a must to have. Can send photos after installation... Again thanks for a great product.


Install time was 1 hour, it took me 20 minutes to remove the spare tire as it was never removed in 8 years! Straight forward and easy install.


Install was easy. Routing the wires took the most time, but, nothard at all.


I thought it would be a challenge to install the electrics for my hitch, but with your kit and instructions, it was a breeze! I completed the install in less than 20 minutes, and worked perfectly right from the start. Great products & service, etrailer!

Hitch and accessories are great, very durable. Thank you for a quality, reliable product!
Doug - 02/27/2019


Easy install and good quality. A must for nice clean wiring of your trailer lights.

2012 Dodge Durango

Installation was easy as the video indicated. I had 2 problems. Neither i suppose are the fault of etrailer but frustrating non the less. After installing the harness I closed the tailgate on my dodge Durango and the passenger side tail light was slightly out of position causing contact with the hatch causing the taillight lense to crack under the pressure of the power liftgate. Second I paid for 3 day shipping which was delayed due to hurricane Harvey, for an additional 4 days. Again not the fault of e-trailer just frustrating to pay $16 for 3 day shipping and have it be delayed

2012 Dodge Durango

I have not had the opportunity to install the Curt hitch or wiring but have removed it from the box and it appears to be excellent quality.
From your Website to your order tracking process including email notifications, etrailer is an outstanding company. The custormer service you provide is only a claim for most companies. You delivered well above my expectations. I am already considering purchases of other products.
Thank you

2012 Dodge Durango

Everything works great! I've been using this for over a year now and had no issues. I buy a lot of hitches and wireing from and everything is always great! including the service. Thanks guys!

2013 Dodge Durango

Easy to install. Installed hitch and wiring harness in about 20 mins. Only hiccup on my side was ran the wiring harnesses next to exhaust and then noticed when I went back to zip tie the wires up tight so I had to go back and re wire the passenger side. So pay attention unlike I did lol. Anyways I recommend this product. It's a plug and play type deal. A 5 year old could do it.

2013 Dodge Durango

Very easy to install, and worked flawless. I even have a factory original tht is faulty. This connector is a fantastic buy!!!!!

2013 Dodge Durango

I cannot review the products that I have purchased yet, because I have not installed them, but I will say that I am fairly amazed that after placing my orders for the Curt trailer hitch, wiring harness and plug mounting bracket on Monday this week all of the items arrived on my fornt porch Wednesday afternoon. This was using the standard ground delivery. Items were shipped from St. Louis and also in Minnesota.

2011 Dodge Durango

This product is awesome! It took my husband less than an hour to attach the hitch and plug in the trailer lights!!! He was very impressed at how easy and heavy duty this product was. He is used to welding and splicing and taking two days to have to attach a hitch..Not any more!!! We will definitely recommend this product and etrailer to all of our friends!!!


Arrived on-time in excellent condition. Only suggestion would be to add a little detail on popping the taillights off. I was afraid I was going to break something. Other than that minor issue, the harness installed just fine and works great!


I have not installed the system yet but I am more than happy with the delivery time of the product. Caleb was excellent on the phone for answering the questions and taking my order. It is rare these days that a company takes time or cares after the purchase. I found the photos and install video's helpful while I was trying to decide on What hitch and wiring package to purchase. If the install is a simple and worry free as the purchase I am sure thing will go great. In today's market place I wish you the best and I am sure this company will do well because so far you guys are 10 out 10 in my book for knowledge, service and product.

2011 Dodge Durango

I was extremely pleased with my order. I placed the order at 8:30 in the morning and received an email within an hour that the items were available and would be shipped within 24-48 hours. An hour later I received another email that my free shipping had been upgraded and I received the item the next day! In this day of internet retailers many forget customer service is still important but etrailer is certainly an exception. I will return to etrailer time and time again for my car towing needs!

2012 Dodge Durango

This wiring harness was very easy to install. The video links on the etrailer site made me feel comfortable enough to give it try. Wiring was completely installed in about 30 minutes.

2013 Dodge Durango

This is my second order from and in both cases I have been very satisfied with the quality of the products as well as fast shipping. I found the web site to be very informative and easy to use and placing my order was very easy to do. I would recommend them and, would buy from them again.

2013 Dodge Durango

Outstanding Quality in the add on harness. Truly one of the easiest installations.


As far as I can tell, the craftsmanship of this harness is excellent. All the lights work great when it is plugged in.

  • Trailer Wiring Harness that Does Not Require Battery Connection for a 2012 Dodge Durango
    We do have Curt wiring harness # C56133 that does not require a connection to the battery. Powered converters are great because the power for the trailer lights comes from the vehicle battery and this also helps to isolate the trailer wiring from the vehicle wiring. Isolating the wiring helps protect against short circuits on the trailer from back feeding to the vehicle wiring and potentially causing major electrical issues on the vehicle. Running a power wire to the battery is not that...

  • Custom Fit Plug and Play Trailer Wiring Harness for a 2013 Dodge Durango
    Trailer wiring harness # C56133 is a custom fit item that will only fit the 2011 to 2013 Dodge Durango. It is what can be considered as a plug and play harness. It just plugs in line with the vehicle tail light wiring and will need to be grounded to a bare metal surface. I have included a link to the instructions for you. Curt also has wiring harness # C56162 that is a plug and play style harness only it requires a direct connection to the battery. This connection powers the trailer lights...

  • All Trailer Lights Blinking When Using Turn Signal on 2011 Dodge Durango
    The most likely cause for all of the trailer lights to blink when using the turn signals and the brake lights not working when the trailer is connected to your 2011 Dodge Durango, is a weak or bad ground connection. Since you have ruled out the trailer wiring as being an issue, I recommend checking that the ground wire from the vehicle's wiring harness is secured to the vehicle at a clean bare-metal surface that is free of any paint, rust or any other debris. Even though it is a new harness,...

  • Trailer Wiring Recommendation for a 2013 Dodge Durango Crew
    The Curt Wiring Harness part # C56133 that you referenced has been confirmed as a fit for your 2013 Dodge Durango so it would work well for you. There is a powered converter harness available as well for your vehicle (part # 118552), that would provide your vehicle with more circuit protection, but it is not required that you use this harness.

  • Trailer Hitch and Wiring Recommendation for a 2013 Dodge Durango
    The recommended wiring kit to go along with the Draw-Tite Max-Frame Trailer Hitch # 75713 for your 2013 Dodge Durango would be the Curt Trailer Wiring Harness Part # C56133. Installation would be pretty easy actually, it would be just a matter of removing the taillight assemblies and then plugging the connectors of the # C56133 inline with the taillight harnesses. Check out the installation instructions I attached for this product for more details. For a ball mount, hitch ball, and pin...

  • Trailer Wiring Harness for a 2011 or 2012 Dodge Journey
    The 2011 and 2012 Dodge Journey requires a powered converter, # 119190KIT. None of the T-1 connectors will fit. I have included a link to the installation details and a video showing a typical installation for you. The powered converter receives the signals from the tail light wiring but powers the trailer lights using the vehicle battery to protect the vehicles electrical system.

  • Which Trailer Wiring Harness for 2011 Dodge Durango
    If all you will ever tow with your Durango is a small flat-bed or utility trailer with bare-bones lighting with one stop/turn/running light per side, for example, the standard # C56133 would work for you. If your trailer has additional side marker or clearance lights, or you might have the need to tow a larger trailer with more elaborate lights in the future, you would be better off going with the powered converter, # C56333. Regardless of what you might or might not be towing in the...

  • Recommended T-One 4-Pole Wiring Harness for 2011 Dodge Durango Without Factory Tow Package
    For your 2011 Dodge Durango without factory tow package I recommend the T-One Wiring Harness # 118552 from Tekonsha. This 4-pole wiring kit includes a powered converter which acts like a safety switch to protect the internal wiring inside the truck in the event of a bad short or other wiring fault on the connected trailer. It is a lot less costly to replace a trailer harness kit than the internal wiring in your Durango. This Tekonsha kit installs mostly by just plugging in connectors...

  • Brake Controller Install and Recommendation for a 2013 Dodge Durango without Tow Package
    You will need to start with a 4-way (if you do not have one). For that you would want the # C56133. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885 that you currently have.

  • Hitch, Wiring and Brake Controller Recommendation for a 2013 Dodge Durango
    Lets start with the hitch, for that our most popular hitch with other owners of Durangos is the Curt Hitch part # C13182. This is a Class III hitch with a 2 inch opening with plenty of capacity. I attached an install video for you to check out. Next we need wiring. You will need to start with a 4-way. For that I recommend the Curt Upgraded Trailer Wiring Harness part # C65133. Now you will need to convert the 4-way to a 7-way so that you can install a brake controller. For that you will...

  • 7-Way Upgrade Kit for Trailer and 2013 Dodge Durango to Install Brake Controller
    I am a little confused as it sounds like you are wanting the parts to install a brake controller in your 2013 Dodge Durango but then you said you don't want to install a 7-way and brake controller. I am assuming you are wanting a way to integrate brake controller wiring to the style of trailer connector present on your tow vehicle currently? But without knowing what type of connector that is, and also knowing that the 7-way style of connector is the standard for use with brake controllers...

  • Parts Needed to Install Redarc Tow-Pro Elite on a 2012 Dodge Durango Without the Tow Package
    If you were to install the Redarc Tow-Pro Elite # RED44FR instead then this would require a little different wiring on your 2012 Dodge Durango. The Prodigy RF # TK94FR installs on the trailer frame so it just needs the trailer light functions and 12V power which is what the 7-Way Upgrade Kit # ETBC7L provides. The Tow-Pro Elite, however, installs on your Durango so the installation will look a little different. You can still use the Curt T-Connector Wiring # C56133, but you'll need the...
