Very nice assembly, direct fit to the existing wire harness, easy install.
Would be nice if there was an option/bracket for mounting the four pole plug.



by:

Works great, no issues, used with multiple trailers so far.

Jeep

the wiring harness fit perfectly and I installed in just a couple of hours front to back and ready to pull the jeep behind the motorhome. the kit came with all parts necessary to install complete without going to find wire ties, splice kits, trailer ends, etc, were all there. good job and will use them again in future needs.

Perfect as we pull our Jeep behind our motorhome almost monthly and has never failed me. Good job e trailer



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.

Eric K.

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

2014 Jeep Wrangler

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.



by:
Jeep

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.

Installed by my dealer.
Have had no
problems with hitch or wiring.



by:
2016 Jeep Wrangler

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!!



by:
2016 Jeep Wrangler Unlimited

Hitch and wiring was easy paesey!! Came out great !!



by:
2012 Jeep Wrangler

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.



by:
2018 Jeep JK Wrangler

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.

Michael R.

Still works great after 1 year. Glad I made this purchase



by:

This hitch looks like a factory installed hitch. Very nice finish and easy installation. Also ordered the wiring harness. It was the easiest installation of a wiring harness I have ever encountered. Awesome experience with etrailer. Will definitely use again and recommend them to all my friends.

The wiring harness is working out great. Couldnt be happier with the product or the terrific service from etrailer.



by:
2017 Jeep Wrangler

This was a pretty simple installation. Just plug-n-play. The connectors matched the factory exactly. I would highly recommend watching the video for the installation. I will recommend this product to anyone looking for trailer hitch wiring.

Joe H.

Both of these products have been working as promised. I have no problem recommending them or your company.



by:

Superior quality,outstanding customer service!
Ask
for Helen or Anna to take your order,they really know their products and will ensure you will get everything you need!
Curt hitches and accessories are second to none.
I will be shopping with etrailer again.

A simple plug and play with zero issues!

I bought this one as a backup, to the original one has been installed for over four years. I Jane never had a problem with this wiring harness. I have traveled from New York to Homer Alaska putting 14,000 miles and it still works great.



by:
2017 Jeep Wrangler

The wiring harness was very easy to install after watching the video on etrailer. The connectors look like they are high quality. Some kind of mounting plate for the connector on the trailer side would have given it a more professional look instead of just letting the connecter "dangle" from the bumper.

Good news, Bob! We do have 4-flat mounting brackets available at the following link.

Wiring harness was very easy to install on our 2016 Jeep Wrangler. No problems of any kind. Needed this for a smaller trailer to haul my golf cart to the campground on.

Phillip M.

Wiring harness worked great! Was very easy to install. I have since sold my Jeep.



by:

This is my second time using etrailer and I can say I have not dealt with a company that is better than this one has been. The last order I made, one of the items was back ordered, so instead of sending me an email they actually called me. That kind of service is sadly lacking in most businesses. I will do business with this company again in the future.

Ron E.

4/1/2016

Initial installation was easy and the harness has performed flawlessly, a very good product.



by:

I purchased this product skeptical that it would work. However, I was amazed that everything worked wonderfully and super easy to install. I loved the videos to help install the part. I am super happy with this product.



by:
2017 Jeep Wrangler Unlimited

Installed the hitch and wiring harness in less than 45 minutes. Fits perfect and looks good can't wait to hook up the trailer.

Bruce

Works great as advertised. Would recommend it and would by again.



by:
2014 Jeep Wrangler

Product showed up very quickly and is totally as described. Super easy to install and wow, I have trailer wiring.
As usual, etrailer just made the whole process easy. The price is well below what I could find it for locally. All good!

  • Brake Controller Recommendation for a 2008 Jeep Wrangler Unlimited
    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 as well. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake...

  • Brake Controller Recommendation for 2016 Jeep Wrangler Unlimited JK Sahara
    It is easy to recommend the Tekonsha Prodigy P2 Brake Controller # 90885. Our customers consistently rate this item very highly for its easy installation and reliable operation. Plus it has the capability to work with both electric drum brakes and electric-over-hydraulic actuators. If you care to trade up then I suggest the P3 controller # 90195 which has the same capabilities but which includes an easier-to-read digital display. Both are proportional type controllers that will slow your...

  • How to Mount 4-Way Connector with Curt Trailer Hitch # 13432 on a 2016 Jeep Wrangler
    There are a few different options for storing the Curt T-Connector # C55124 on your 2016 Jeep Wrangler. The first couple of options are exactly what you mentioned, you can let it hang there or zip-tie it, but either of these options don't look that great. We do have the mounting bracket # 18144 which can be mounted to the body of your Wrangler but I believe you are looking for something like the Easy Mount Bracket # C58001 which basically clamps around the receiver of your Curt Receiver...

  • 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...

    Both the Tekonsha T-One Vehicle Wiring Harness # 118416 and the Curt T-Connector Harness # C55124 referenced in your question are confirmed to fit your 2017 Jeep Wrangler without the tow package. These will both install in the same exact manner, plugging directly into existing ports located behind the driver side tail light on your vehicle, and will provide a 4-way flat for connecting with a trailer. The only difference between these two products is simply the manufacturer. I like to...

  • 7 and 4-Way Trailer Wiring Recommendation for 2017 Jeep Wrangler Unlimited
    You will need to start with a 4-way (if you do not have one). For that you would want the # C55124. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. This gives you the ability to have a 4-way too. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller. For a brake controller...

  • Can Hitch be Installed with Pavement Ends Rear Bumper PE4591101
    The replacement rear bumper # PE4591101 has about the same height (6 inches) as the stock bumper on a 2012 Jeep Wrangler Unlimited. This means you can install a trailer hitch like # 13432 to tow a small utility trailer. You'd also need trailer wiring to activate all of the lights. For that you'd want the part # C55124. Since you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and...

  • Upgradable Towing Set-Up Options for a 2013 Jeep Wrangler Unlimited Towing Pop-Up Camper
    You can start off by installing just a hitch and trailer wiring to start your pop-up camping experience. For a hitch I suggest the 2-inch Curt Class III hitch # 13432. This hitch offers a 3500-lb maximum towing capacity and is rated for use with weight distribution should you decide to add such a system later on. The install process for this hitch is shown in the linked video. It requires no drilling, but does require permanent removal of tow hooks if present. You will also need to temporarily...

  • Brake Controller Recommendation for a 2013 Jeep Wrangler Unlimited
    The anti-sway feature you have in the computer of your 2013 Jeep Wrangler Unlimited would not be an adequate substitute for a brake controller for towing a trailer. For a brake controller I would recommend the Prodigy P2 Brake Controller part # 90885. This is our best selling brake controller because of how well it works and how easy it is to setup. To install the brake controller you will first need a 4-way if you do not have one. For that you would want the part # C55124. The next...

  • Troubleshooting Constant Right Turn/Stop Trailer Light Function on 2018 Jeep Wrangler
    Thank you for all of the insight, it really helps narrow down what we need to be looking for. I believe you are correct that the problem is on the vehicle wiring. If your 2018 Jeep Wrangler is a JK then you have something similar to the Curt # C55124 which is a simple tee solution but if you have the JL Wrangler then you have something like the Curt # C56407 which has the whole module setup. With the JK wiring I actually believe the issue might be on your OEM wiring but for the JL the...

  • 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...

  • Hitch Cargo Carrier, Cargo Bag, Light Kit and Lock Recommendations for 2014 Jeep Wrangler
    Selection of a hitch cargo carrier that will fit nicely at the back of the vehicle is best done after taking one simple measurement. Measure from the center of the hitch pin hole back to the rear-most part of the vehicle, which is typically the back edge of the rear-mounted spare tire on a Jeep like your 2014 Wrangler. You can refer to the linked article for illustration of how to measure. The Cetrailer hitch cargo carrier # e98874 sits 9-1/2 inches from the hitch pin hole when folded...

    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.
