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.

So easy to install. I found the video on YouTube and it was just as easy as they showed in the video. No cutting and splicing wires. Just unscrew the tail light, plug it in, put the light back, and then zip tie the loose wires. Easy Peasy. I watched another video from Uhaul and it was way more complicated.



by:

Best kit simple installation and reliable. Beats the old cut, wire, and tape method by a long shot. This is the only hitch wiring kit I’ll ever use from this one on.

Still absolutely the best investment in trailer hitch wiring kits I’ve ever made.



by:
2014 Jeep Wrangler

I installed the Curt T-connector wiring harness w/4-pole flat connector with the no-drill bracket, along with a Curt trailer hitch receiver and the max-tow adjustable ball mount that I purchased through eTrailor and everything worked out perfectly. The installation of everything completed in about 1.5 hours and I was able to tow my HD motorcycle to the 2014 West Virginia Mountainfest on my 2014 Jeep Wrangler Unlimited Sport. My hats off to Ricky S at etrailor for helping me out and following up with my order. Anthony

Wiring kit worked great. I used it to hook up lights on a trailer tongue mounted motorcycle carrier (the kind with no wheels). Unfortunately the lights got damaged pretty badly from an offroad trip in the Upper Peninsula of Michigan, but the wiring kit is still attached and working fine.



by:

This would be 5 stars for quality of product, ease of install and fitment. I gave it 4 stars because there's no protection for the wires and it runs close to the exhaust system. The harness is extremely easy to install. The connections plug directly into the existing harness. Drop them through the wheel well and use some zip tie anchors to secure it to the body. I used windex to ensure a grease free surface. Created a secondary loop to store when not in use.
All in all a good quality product that's easy to install and works as expected.

My hitch for the Jeep came in 3 days, and both the hitch and the wiring kit installed in under an hour. Very easy, and a perfect fit. Will be using for a bike rack, and a utility trailer.



by:

This is a very nice harness. It took about 5 minutes to install. The plastic connector clips fit perfectly, just like the factory harness clips. I wish there was a mount for the trailer connector though. Then it would be AMAZING. I ended up just bundling the extra wire under my new Curt hitch.



by:

Great product! Met all expectations and made the trailer wiring work a breeze. Thanks.

Everything went together perfectly. Unlike most things you order, this kit needed nothing else. All wire connectors and bolts were included. Very nice kit.

This is so easy to install... Make sure you have an extension for your driver to set the grounding wire... Great price, Shipped quickly... easy install... videos showing you how to do it... What more could you ask for? Highly recommend this product and company!!

Bought curt wiring kit, and it was easy to install as well!! This was probably the easiest thing I've done to my jeep!



by:
2012 Jeep Wrangler

Simple to install. Only snag I ran into was that two of the pre-cut holes in the frame were too small for the bolts, so I had to use a drill bit to slightly widen them. Otherwise, very simple.

Wiring T-Connector arrived 1 day earlier than expected with the trailer hitch. It was very easy to install with the simple instructions. Well made product and looked just like the factory wiring and connectors. I didn't noticed on the website a bracket to order but I had a Z type piece of metal that I was able to make bracket out of and mount to the frame of the vehicle.

  • What 4-Way Trailer Wiring Harness For 2024 Jeep Grand Cherokee L
    Hi Tyler, From what I can find you got the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C55124 which is not a fit for a 2024 Jeep Grand Cherokee L, it is a fit for some Jeep Wranglers up to 2018. Instead, the correct 4-way wiring harness for your 2024 Jeep Grand Cherokee L (assuming you do not have the factory tow package) is the following: - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C27BR

  • Can I Install Both a Flat Towing Wiring Harness and a 4-Way Connector on a 2018 Jeep Wrangler JK?
    Yes, so long as you don't try to use both of them at the same time. The Curt T-Connector Vehicle Wiring Harness item # C55124 will work as a 4-flat connector and plugs into your Jeep's existing wiring. If you try to flat tow your 2018 Jeep Wrangler JK with say a bike rack on the back or a cargo carrier that has lights on it then the 4-flat connector will not work, only the Hopkins item # HM56200. The Curt item # C55124 is confirmed to fit the 2018 Jeep Wrangler JK's without the towing...

  • Parts Needed to Install Prodigy P3 Brake Controller in 2018 Jeep Wrangler Unlimited
    Since the 2018 Jeep Wrangler does not come with factory brake controller wiring you'll have to hardwire in your P3 part # 90195. You will need to start with a 4-way (if you do not have one). For that you would want the # C55124. 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...

    Hi Jess! We can definitely get your 2009 Jeep Wrangler set up with a 7-way trailer wiring harness. Guessing you do not have the factory towing package? If you are unsure, have a Jeep dealer run you VIN and they will be able to tell you. If you have it, you can use the Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket, Chrysler/Dodge OEM Plug Adapter # HM40975-11933, but if you do not, there are a couple things you will need.

  • Recommended Trailer Hitch Receiver for 2018 Jeep Wrangler Unlimited JK and JL Models
    All of the JL Wrangler Unlimited hitches we carry will work on the JK Wrangler Unlimited models, but there are some JK model hitches that are not compatible with the JL Wranglers based on fit guide from the manufacturer because they have a shorter receiver. The bolt mounting holes are in the exact same location. Unless you are doing rock crawling, I recommend getting the longer receiver like the # e98856 or Curt # C13392 which will allow more accessories such as bike racks and cargo...

  • Parts Needed to Flat Tow a 2016 Ford C-Max
    The easiest system to set up and use is the Blue Ox Patriot # BLU37TR, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles. For a base plate kit I would recommend the part # 524432-1 which I attached an install video for as well. The most popular compatible tow bar is the Falcon 2 # RM-520. For safety cables you can use # RM-643. The coiled design helps keep the cables off...

  • Does Curt 4-Way Wiring Need to Connect to Right Tail Light on a 2017 Jeep Wrangler
    Hey Troy, thanks for reaching out! The Curt T-Connector Vehicle Wiring Harness # C55124 is only designed to tee in behind one of the tail lights, so you'll want the kind people at U-Haul to recheck their installation and make sure they gave you a working product. The T-One Wiring # 118416 from Tekonsha tends to be a bit more reliable and it has diodes built into it to help everything function properly, but regardless, U-Haul shouldn't be sending you away with a product that isn't working.

    There are a few different trailer wiring harness options for a 2015 Jeep Wrangler Unlimited. The Hopkins Endurance Quick-Install 7-Way Trailer Connector part # HM42190 is only for models with the factory tow package. If you don't have the factory tow package then there won't be a square plug for the above and instead you'll need to start with a 4-way and adapt this to a 7-way.

    No, it will not. The correct Draw-Tite Hitch for your 2018 Jeep Wrangler JK Unlimited Sport is item # DT78MR. This hitch is custom fit and will bolt to your Jeep's standard bumper with included hardware. I have linked an installation video below to help you get it set up. Neither the part number 87479 (ours is item # 75270 ) you mentioned or item # DT78MR are part of Draw-Tite's Hidden Hitches branding. They do not make a hidden hitch for a 2018 Jeep Wrangler JK Unlimited Sport. I hope...

  • Troubleshooting 2013 Jeep Wrangler Unlimited Wiring Issue with Curt 4-Way Harness
    Sometimes the issue with a wiring harness like what you have with the C55124 is an issue with the factory wiring. Other times it is with a bent pin in the connection. Other times it is a bad ground connection, and then there can also be a wiring short. You will need to do some troubleshooting using a circuit tester like # PTW2993. This tester will allow you to check the functions of your factory wiring. My recommendation is to unplug your harness and check all your factory wiring...

  • Selecting Hitch-Mount Cargo Carrier for Use on 2016 Jeep Wrangler Unlimited Rubicon
    It is easy to measure to confirm the fit of a hitch-mount cargo carrier on a vehicle such as your 2016 Jeep Wrangler Unlimited Rubicon that has a rear-mounted full-size spare tire. Simply measure from the hitch pin hole on your receiver tube to the rear-most part of the vehicle - in your case this will likely be the back edge of the spare tire. This dimension tells you the amount of clearance you need from a hitch carrier like the Pro Series Cargo Carrier # 63153. The linked article covers...

The only special tool needed is a torque wrench like # ALL944001 which is needed to secure the fasteners to the specs shown in the linked instructions.

  • How to Transport 333-lb Wheelchair on 2016 Jeep Wrangler Unlimited with Rear Spare Tire
    The spare tire on your 2016 Jeep Wrangler Unlimited poses a clearance challenge for transporting a wheelchair on a hitch-mounted carrier. The use of a hitch extension like # C45791 will get you an extra 8-inches of clearance at the spare tire, but the use of any adapter like this also costs you 50-percent of your hitch capacity. This is due to the extra leverage applied to the hitch from the load being further away from it. The 2-inch hitches for your Wrangler Unlimited (shown on the linked...
