Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - C55124

Average Customer Rating:  4.9 out of 5 stars   (384 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.

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.

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.




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.


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

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.


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

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




by:
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:
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.




by:
2016 Jeep Wrangler Unlimited

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:
Jeep

Good Quality, Easy plug it in install on my Jeep JK....
The length of the harness was great to allow clearances etc...
I suggest adding some type of "Wire Loom" to protect the harness against sharp edges of the body and frame. "A Great Plug & Play" product




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.


Comments
Still works great after 1 year. Glad I made this purchase
Michael R - 04/29/2019

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.

Hitch and wiring was easy paesey!! Came out 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.


Comments
Good news, Bob! We do have 4-flat mounting brackets available at the following link.
-- Etrailer Expert Laura E - 11/07/2016


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.


Comments
Initial installation was easy and the harness has performed flawlessly, a very good product.
Ron E - 04/01/2016

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

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

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.


Comments
Both of these products have been working as promised. I have no problem recommending them or your company.
Joe H - 04/24/2018

Easy install. Took maybe 20 minutes. Overall took an hour for hitch and wiring!! Too easy!!


Comments
Very easy install. Plug and play. Using receiver plug with LED display. Works perfect. No issues as of yet. Great product. Fast shipping.

Wiring harness installed in less than ten minutes. Instead of drilling hole for ground wire as directed, i attached the ground to the lower right taillight screw retainer.


Comments
The products i purchased still look like new. I have had not a single issue with any of the items i purchased. Really dresses up my jeep nicely.

2016 Jeep Wrangler Unlimited

I ordered this and the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" - for my jeep several weeks ago. The hitch arrived within a few days but the wiring harness was not in the box. I contacted customer service and they were terrific about the situation. They asked a few questions, never doubted that I did not receive it, and promptly reshipped the wiring harness. I received it a few days later.

I can't say enough about how pleasant the e-trailer team was to deal with, I understand they could have doubted my story that I didn't receive the wiring harness and given me a hard time. Instead they were anxious to fix the situation and actually followed up with me twice after they reshipped it. Once to give me the tracking # and once more to let me know it had been delivered.

Great product, it fit great. Even better customer service. I will absolutely use this team again for my future trailer needs.

  • Wiring Harness Not Functioning Properly on 2014 Jeep Wrangler Unlimited with Right Hand Drive
    Wiring for standard domestic production vehicles may differ from that in vehicles produced for markets outside the U.S. If your Jeep Wrangler Unlimited was produced for another market its wiring could be different and this could explain the issue with the lack of power to the right-hand turn signals using wiring harnesses you've tried. Several of the 4-pole harnesses we offer for your 2014 Wrangler Unlimited, part # 118416 from Tow Ready and # C55124 from Curt, are noted as possibly requiring...

    If you already have a working 4-pole flat trailer connector on your 2011 Wrangler Unlimited you can easily convert this connector's lighting signals into the round RV-style 7-way format. You will use part # 37185 from Hopkins, which is a combination 4-pole and 7-way in one unit. This lets you retain both connector formats on your Jeep. This Hopkins part includes a metal mounting bracket, installation hardware and connectors to allow you to make additional circuit connections on the 7-way...

    The only difference between the Curt T-Connector Wiring Harness, # C55124, and the Tow Ready T-One Vehicle Wiring Harness, # 118416, is that they are made by two different manufacturers. They are essentially the same exact wiring harness coming from two different companies. Both Tow Ready and Curt are reputable companies so you will not be sacrificing quality with either harness. When deciding which harness to purchase, I would go with the least expensive option to save money. I have attached...
