Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located at the rear of your vehicle, on both the driver's and passenger's sides. You will find the harness behind protective covers near the rear bumper.


Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


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.

Straight forward installation. Installed on 05 Wrangler 2-door. Passenger side tail light plug was a little hard to locate. It was tucked up high in the fender. Not shown in installation video. Otherwise great product and easy installation.

Very nice website that made it very easy for me to find the trailer hitch and wiring kit I was looking for at a great price and was delivered very fast. I really enjoyed the detailed information, pictures and even installation videos of the products I was purchasing that made it easy for me to install on my own. Curt hitch is very well made and was a breeze to install as was the Tekonsha plug and play wiring harness. The only thing I found odd was etrailer applied their advertising sticker on the hitch upside down, I had to remove it. I highly recommend etrailer and will definitely buy from them again in the near future.

Great product, much better than those that cut into and attach to individual wires. Took about 30 minutes from beginning to end. 2001 Jeep Wrangler on the driver side the connections were made by removing the brake light assembly and on the drivers side the connections were made from below and behind the right tire. It was easy to drill the bumper with a hole saw making a nice out of the way connection to a one piece flat and round connector, see picture.

I have bought two hitches for our Kia's and a wire harness for our Jeep from etrailer. The product always ships quickly and the customer service is always very helpful and friendly. Their videos used to show installation has made every step very easy and without surprises. All of my hitch and accessory purchases will be thru etrailer from now on.

EXCELLENT PRODUCT. ONE HALF HOUR AFTER OPENING THE BOX I WAS DONE WITH THE INSTALLATION AND PUTTING TOOLS AWAY. IF I WAS MORE FAMILIAR WITH THE PUSH CONNECTIONS AND THE FIRST DRILL BIT WAS IN GOOD CONDITION IT WOULD HAVE GONE MUCH FASTER. IF I WERE TO DO THIS AGAIN I THINK I COULD GO FROM AN UNOPENED BOX TO ALL DONE , TOOLS PUT AWAY AND RELAXING INSIDE IN FIFTEEN MINUTES. SHIPPING WAS QUICK AND GEORGE KEPT ME UPDATED EVERY STEP OF THE WAY. IF YOU ARE THINKING OF USING THIS COMPANY...DO IT!

This was an easy setup to install. The hitch went on my Jeep without much fuss, the wiring kit was easy to connect, and I think I was done in about an hour, start to finish. It's holding up well, in terms of finish and corrosion, and I'm really pleased with the purchase. Thank you, etrailer!

2005 Jeep Wrangler

I bought the T-One trailer harness for my 2005 Jeep Wrangler. IT WAS SSSOOOOOOO easy to install, it took longer to get the dried mud off my plastic flaps than it did to install this GREAT PRODUCT about 1/2 an hour. I did it without lifting my vehicle, just pulled the flaps down reached in and BANG done. No trying to separate wires, no hoping that the piercing clip will actually hit the copper. Just separate the plug ends snap the T-one in place, repeat for the other side, tie wrap the harness to the frame. DONE!! I WILL NEVER go through the splicing or piercing clips again to install a wiring harness. I love this, it was a great experience. THANK YOU FOR MAKING THIS!!!

  • Brake Controller Install on 2001 Jeep Wrangler
    To install a brake controller on your 2001 Jeep, you will first need the T-1 Connector, part # 118409 if your Jeep does not already have a 4-way trailer connector. You will also need the Brake Controller Installation Kit, part # ETBC6 if you need a 6-way trailer connector, or part # ETBC7 if you need the 7-way. The install kits contain everything necessary for installing a brake controller on your vehicle. Finally, you will need to choose a brake controller. I would recommend the Tekonsha...

  • Tekonsha Plug-In Wiring Adapter for Electric Brake Controllers for 2005 Jeep Wrangler TJ
    Jeep Wrangler models are not equipped with the under dash connector for installing a brake controller, so there is not a harness that would allow a plug and play installation available, I am sorry to say. Fortunately, a brake controller can be easily installed using our brake controller installation kit, part # ETBC7. The kit includes an adapter that will convert your existing 4-pole trailer connector to a 7-way. If your Jeep does not already have a 4-pole trailer connector, one will need...

  • Recommended Trailer Hitch and Wiring for 2005 Jeep Wrangler Unlimited for Small Uhaul Trailer
    For your 2005 Jeep Wrangler Unlimited I recommend starting with the Draw-Tite # 75193. Then I recommend using the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118409 which installs behind your tail lights. If your trailer doesn't require electric brakes then you can simply add mount # 18144 and be good to go. Most Uhaul trailers have surge brakes if brakes are required so no brake controller is needed. If your trailer requires electric brakes, I recommend the same...

    For your 2005 Jeep TJ Unlimited Rubicon I recommend the Redarc Tow-Pro Liberty Brake Controller # RED24FR. This proportional brake controller has a 3-Axis accelerometer which allows you to mount the main unit in any position out of sight which means it won't be taking up space in your Jeep. The control knob can mount anywhere in your vehicle and allows for fast and easy adjustment. You will also need the Universal Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers # RED69FR to...

    I can definitely help and set you up. We do have a plug and play harness available for your 2005 Jeep TJ. I recommend the Tekonsha # 118409. This will plug right in below the vehicles driver and passenger side tail lights and give you a 4 flat connector. If you need to set it up with a 7-way plug we have the # ETBC7 kit. This will include everything you need to upgrade the existing 4 flat to a 7 way connector. This kit is not a plug and play install so it will require a bit of wiring....

  • Can the Fuel Tank Be Removed from 2001 Jeep TJ With Curt Trailer Hitch Receiver 13408 Installed
    From what I have found, there are four bolts holding the fuel tank in place at the back of your 2001 Jeep TJ. The Curt Trailer Hitch Receiver # 13408 covers these bolts once it is installed, so it would have to be uninstalled in order to access them and remove your fuel tank. I recommend the Curt Trailer Hitch Receiver # 13430 instead. This hitch sits slightly further back, leaving those bolts accessible. There should be plenty of clearance to remove the fuel tank, although it may make...

  • Trailer Right Turn & Right Brake Lights Do Not Work After Installing Wiring Adapter # 37185
    Both trailer right turn and right brake light signals are carried on the same wire, a green wire in the case of the Hopkins adapter # 37185. Since these are the only functions not working I suggest you first test the green wire on your Jeep's 4-pole harness, the harness that plugs in to the Hopkins adapter. You'll want to look for signs of discoloration or corrosion on the contact pin for the green wire; clean as needed. If you have a circuit tester like # 40376 you can test that pin while...

  • Parts Needed to Install 7-Way Trailer Wiring Harness in 2005 Jeep Wrangler
    The reason the wiring harness of the Hopkins 7-Way Kit part # HM40975-11933 seems short is because it's for connecting to existing trailer wiring on your 2005 Jeep Wrangler. If your Wrangler did not have a 7-way present at the rear of it then this would not work. You will need to start with a 4-way (if you do not have one). For that you would want the # 118409. 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....

    Both the Tow Ready T-One Wiring Harness # 118409 and the Hopkins Plug-N-Tow Wiring Harness # 42615 will work on your 2000 Jeep TJ Wrangler Sport. The difference is what you mentioned, how they install to the vehicle. The Tow Ready harness uses T-One connectors that will plug into connectors on each side of the vehicle.

You just find the connection points beneath the rear bumper. For a 7-way connector you will need part # ETBC7. Usually, a 7-way connector is used because the trailer has brakes. If that is the case then you may be interested in a brake controller like part # 90885. This is our most popular brake controller because it is easy to install and operate. I...
