This design fits directly behind the driver's side tail light, making installation a breeze in just about ten minutes or less. Perfect for DIY enthusiasts or those who want to skip the mechanic.

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.Everything went together perfectly. Unlike most things you order, this kit needed nothing else. All wire connectors and bolts were included. Very nice kit.
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.
Instructions did not match the wiring on my jeep

This harness does fit a variety of Wranglers. When that happens, at times the instructions can be very vague and even seem to be a bit basic. I have attached the install video for your year. The videos help me a lot because it will give me those finer details I need in these situations.
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.
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.
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.
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.
Works great, no issues, used with multiple trailers so far.
Excellent videos, super easy install.
Installed by my dealer.
Have had no problems with hitch or wiring.
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!!
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
Easy install and great service
Bought curt wiring kit, and it was easy to install as well!! This was probably the easiest thing I've done to my jeep!
Hitch and wiring was easy paesey!! Came out great !!
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.
Representative was very helpful in explaining everything
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.

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

A simple plug and play with zero issues!
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.

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