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. Converter is made using SMT to ensure superior performance.

Installation
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.
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.
A tail light converter is built into this T-connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Looks like it is exactly what I ordered. Will be installing tomorrow. Was a surprise the product got to me as quickly as it did. I would choose you guys for future trailering needs
I just received this product earlier today. As a person who works the graveyard shift there's not a lot of time to do things during the day. The installation was as simple as the video on etrailers web site. All in all about 30 min for me to install this . Harness came in a nice box with etrailer company name on it. Shipping was fast ,3 business days from Missouri to Texas,using cheapest shipping option.Very happy customer highly recommend etrailers services and product
Great product with easy to follow video instructions. I would recommend it to my friends. Thank you!

so far so good minus the small problems I outlined earier
Great products and service. I was able to order everything I needed to add a tow hitch and ball to my 2006 Jeep liberty. Very fast shipping. They even called me to verify orders and availability. Clear and easy to follow installation instructions. I hauled an U-Haul trailer from Texas to Ohio without any issues. Even bought a trailer and use it frequently for hardware stoe runs.
Just hooked up my wiring package Monday and got lucky to grab a great deal on a 5x10 trailer on Tuesday,hooked it up and everything worked great.With the very helpful video installation was a breeze, only took me about 30 minutes.I am now a very happy customer and if I need anything else trailer related I'll be sure to stop by again.Thanks guys for a great product!!
Very nice set up it took about 30 minutes to do had a little trouble getting the right side of the wires up through to the Light but not to bad. With the connections there is no splicing needed I just zip tied the wires up and used a couple ties left loosely to let the trailer connecter loop through up and out of the way until needed.
Followed a You Tube video and did the complete install in about an hour taking my time! I did buy some longer zip ties so I could strap the wires to the frame of the hitch but didn't have to.
Just got it yesterday and put it on when I got home from work. It's working just fine so now I can pull my trailer with all the lights working. I'm giving you thumbs up on this!!!!!!!!
This wiring harness was the exact one I need. Took me only minutes to install.
Great service all around
This wiring kit was super easy to install. I watched the video install first and then installed. The wiring kit works great!
I loved. plug and play. no problem with the pluging in JEEP LIBERTY 4x4 2006 TRAILER WIRING was easy to install.. abaut
So far good service and good delivery. Thank you
It went in smoothly I’m 74 and I was able to get it installed in a couple of hours. Someone younger could most likely do it in an hour. The Video was awesome and probably saved me and hour or two. Thanks etrailer
After one year I couldn’t be happier. This fit my 2006 Jeep Liberty perfectly. And the video made it a snap to install. I tow my boat and everything works flawlessly.

Works great after one year of towing my boat to the launch. Would highly recommend for the Jeep Liberty V6, towing 2,000 boat with ease
It was easy to install the wiring harness on my 2007 Jeep Liberty Sport. I suggest anyone installing this to make sure the surfaces you will apply the double stick adhesive strip is clean or the box will come loose. Also, take your time figuring out exactly how the little red release button operates to unlock and separate the existing light connector from the tail light. Its really simple if you do. Otherwise, you might break it. Get a big piece of cardboard or equivalent to lay on the ground for when you route the wiring from the first tail light connection underneath the back bumper over to the other tail light. I am happy with the shipping, quality, ease of installation and operation of this vehicle wiring harness. I recommend it for anyone wanting a vehicle specific, trailer wiring harness that's easy to install.

Still working fine after one year. I recommend applying bulb grease electrical lubrication to both trailer electrical connectors to keep moisture out of the connectors. keeps them from turning green with corrosion
I received the wiring kit in a very reasonable amount of time and installed it this morning in less than an hour. The ease of installation was fantastic and though I haven't used it yet my vehicle lighting seems to be working well. Plenty of good quality wire supplied, easy instructions. One note: it's suggested the battery gets disconnected ( a good idea),which I didn't remember until I was almost done but I'm wondering if pulling a couple of fuses would be easier. Regardless, leaving the electrical system connected didn't seem to be a problem. So far, I'm definitely happy. Thanks!

Great! I just finished moving and needed to rent a trailer several times. The wiring harness is still working perfectly and the insulation intact.
The wiring kit for the 2006 Jeep Liberty fit perfectly and was a breeze to install. This is my 2nd experience with these wiring kits and they are simply amazing and simply plug into existing vehicle wiring.
The instructions were clear and easy to understand, and again, the hook-up and installation could not have been easier or simpler.
Thank you etrailer.com Ray S. Eckert, Colorado

Wiring harness is great - exact fit and exactly what I needed !!!!!!!
2005 Jeep Liberty trailer wiring harness was quick and easy to install. It took about 20 mins. start to finish and only required a few tools from my toolbox. I highly recommend this product to anyone who owns a 2005 Jeep Liberty. The online video was so nice, it helped tremendously on the install!.

Highly recommend this harness! Since the install on the 2005 liberty Ive installed another harness on my 2007 Commander. Again, very easy to install.
Easy peasy all I did was Plug and Play like the video said came with all the parts I needed to get it on my Jeep it was easy
Wow! Could it get any easier? Install was a breeze. Referred to the video about where to mount the converter, followed the directions, and done! I also ordered a set of aftermarket tail lights and installed them along with the harness. No problems at all. Start to finish was approximately 15 minutes. Thanks etrailer for an awesome product!

One year later, everything is working excellent. As a matter of fact, the factory wiring harness was burning out bulbs about as quick as I could change them. Since I have installed the harness from etrailer, I have not had to replace one bulb in the year Ive had it installed. It dealt with a U-Haul 4 pin, twin axle trailer for over 600 miles like a champ! Not a glitch. Still goin strong. Like I said a year ago, awesome product! Thank you etrailer.
I finally got around to installing this Jeep Liberty wiring harness. I had another one installed from maybe 6 years ago and the left turn signal stopped working so I ordered a new harness since I suspected something went wrong inside the sealed box that combines the brakes and turn signals. This one installed easily and worked so I am a happy camper again.

Ive used this connector twice in the past year, hooked right up to a rented Uhaul trailer no problem , all lights still perform and function as they should. Very happy to have the option to tow, since I dont own a truck. Etrailers has made it possible. By the way my Jeep was hit from the back smashing the back swing door in the etrailer harness was uneffected,didnt fall off from its mounting position wow Im impressed . thanks for a great product
