  • 4 Flat
  • Custom Fit
  • Trailer Hitch Wiring
  • Powered Converter
  • Tekonsha

Quickly and easily install a 4-way trailer connector on your Jeep Wrangler 4xe with this custom wiring harness. T-One connector plugs directly into existing wiring. Powered ModuLite reduces strain on wiring system.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily
    • Locate connection points behind tail lights
    • Plug in T-connector
    • Run hot lead to car battery

  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 5 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One 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 access cover and the tail light assemblies to access this harness.


T-One Connection Location Points Behind Tail Lights

Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle. 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.


ModuLite Power Module

A ModuLite power module is built into this T-One connector. With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Another successful order and install from etrailer.com! Always fast shipping and excellent installation guide videos! Installed on 2021 JL Wrangler EcoDiesel.

2018 Jeep JL Wrangler Unlimited

Easy to install, no cutting of factory wires, perfect. Be aware that the 2018 JK and JL have different taillight plugs, and you need to get the correct harness. This one only works on the JL.

On Sat 3/9/24 I called etrailer and attempted to order Roadmaster Direct-Connect Base plate.., phone lines down so you couldnt place my order. The price then was 397.71. You called me back following Sunday and was able to place my order. The price on same item one day after my first attempt was now $[XX] which I paid not reallizing the price had increased by $[XX] dollars . I checked your site and the price had indeed increased to $[XX]. I checked the site again on Tuesday 3/12/24 and the price had decreased again to $[XX]. I called you to have my account credited the $[XX] as I had not even received the item yet. You told me that couldnt be done. You would however re order and I could return the one that hadnt even arrived yet,, but that I would have to pay shipping of $[XX]. How ridiculous does this sound? You told me that if I paid for a gallon of gas one day and the price dropped the next day i couldnt expect the gas station to take it back so etrailer wouldnt credit me the $[XX] either. I can’t believe this happened even as I write this review it sounds so stupid. I feel I was over charged $[XX] and think I’m still due a credit. I have been a customer for years but no more.

Awesome product. Works as advertised, I would purchase again. Easy install and great instructions.



by:

Kit is well organized and seems to have been well thought out. It is a pain in the rear to run the power line all the way to the battery but has to be done. I keep asking myself why I can't just splice the yellow, green and brown wires into the taillight wires and call it good. I supposed that the little gremlin in Jeep's computer would be upset and keep sending messages that there is a problem with the lights.



by:

Prompt with replies to my questions. Answered my questions. Gave me options based upon what she perceived my need was. One of the best ONLINE LIVE CHAT EXPERIENCES that I have ever had.

I prefer to use this Tekonsha module for the vehicle that don`t have the factory tow harness. The module was tucked away in the body cavity behind the drivers side tail lamp assy. All wiring was covered in HD split loom. All wiring was concealed as much as possible by running them through the cross rail and frame rail up to the battery positive terminal. I did lengthen the green wire on the passenger side to accomplish this. All connections were done with heat shrink connectors. Installation did take longer than usual based on the wire routing I chose. Overall I am totally satisfied with this product.



by:

Installed after watching video. Worked as advertised after completion. Took about 2.5 hours to install. I took my time and made sure all wires were secure and out of the way of any heat source.

I've purchased a handful of trailer hitches/wiring harnesses over the past 10 years and they have always been awesome!! Quality products and fast shipping every time!! Just recieved a new class 111 hitch & wiring harness for my 2018 Wrangler JL and installed the hitch in less then 10 minutes and the wiring was approximately an hour after watching the video provided on their website. Never been disappointed!!

works well, instructions are complete, everything plugged into existing wiring.

once i got the right one it has worked great no problems



by:

Good quality and clear instructions. This is so much better than the old days of splicing into the harness.



by:

very easy install thanks to the outstanding video. Adding this and an $80 -2 inch receiver was way cheaper than buying from the dealer. Since I had the taillights off, i threw in a fuel filler door at the same time.

Great harness

Perfect fit and easy installation too. I would buy again.

I looked at a lot of auto stores . No one could come up with what I needed.
Contacted etrailer. Problem solved.
Thank you, etrailer!



by:

Everything needed was included, products after a year - so far so good.



by:

Jeeps are notorious for electrical problems. This product isolates the automotive system from a trailers systems. Very good idea and I love it. My background is in aircraft electrical systems. I have worked in this field since 1977. This is a great product. I'll buy another if needed and I'll recommend it to others.

I am not one to work on my vehicles, mostly because I find it to be of very little interest.” Unfortunately,” with the economy heading south and prices soaring “ AGAIN “, I found myself in a sqeeze.
I put on my big boys work wear nand attacked the installation of the wiring harness kit for My 2021 Wrangler 80th anniversary Jeep.
The directions were very easy to follow and before I knew it, I was wrapping it up. Start to finish in one hour and forty five minutes. Thank you etrailer

I watched the install video. installation was easy. took about an hour.
Works great.
Transaction = faultless.

Perfect package - comes with everything you need and good instructions. I found a video on the etrailers site was more helpful than the printed ones.



by:

I contacted etrailer in advance of buying the items needed to add a trailer hitch to my 2021 Wrangler unlimited Sahara. I was assured everything would bolt right up and the wiring kit was made specifically for my new jeep. When I received my wiring kit, it was for a jeep with the battery on the opposite side of the vehicle. So the instructions were different and it was more of a chore routing the wires from the battery to the tail lights. Just barely had enough wire to reach the other side of the vehicle. I ended up having to hire a shop to facilitate the install and spent over $200 for the install due to the difference between the items, instructions, and my Jeep. I wouldn’t be so frustrated except I took the time to reach out to etrailer staff and I was assured there would no problems.

When it comes to routing the power wire to the battery you can route the wire over to the passenger side at the rear of the front, it does not matter and it will not have any affect on the install or the system. You will just want avoid places where the wire would be pinched or exposed to heat along the frame rail. We do have a FAQ that is helpful.

Wiring working excellent on my 23 Jeep Gladiator. Great company to deal with, you can't go wrong

  • Difference Between Curt & Draw-Tite Trailer Hitches For 2018 Jeep Wrangler Unlimited
    Hi Ken, Starting with the wiring harness, I can verify for you the correct fit for the 2018 Jeep Wrangler Unlimited without a tow package is indeed the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786. Then for the hitches, the biggest difference between the Curt Trailer Hitch Receiver # C13392 and Draw-Tite Trailer Hitch Receiver # DT78MR is the length of the receiver. The Draw-Tite has a shorter receiver that can make it a bit more of a pain to add a ball mount...

  • Trailer Hitch, 7-Way, and Brake Controller Recommendation for 2018 Jeep JL Wrangler Unlimited
    For your 2018 Jeep Wrangler JL Unlimited the Draw Tite part # DT78MR is a confirmed fit and would be an excellent option. For trailer wiring you'd need to start with a 4-way and then convert it to a 7 and 4-way. For that you'd need the part # 118786. 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. It also leaves you with a 4-way on the side of the socket as well. If you do have trailer brakes you would need...

    Hello Carlos, Yes, you can most definitely secure the converter in the inside of the driver side rear light housing.

I went through the reviews and I see that one of our customers did the same thing, I attached the picture of where he installed the converter. I would also recommend grabbing a Mounting Bracket 4-Pole Flat # 18144 for a clean looking install. Happy...

  • Brake Controller and 7-Way Recommendation for 2019 Jeep Wrangler Unlimited
    To install a 7-way and brake controller in your 2019 Jeep Wrangler Unlimited first requires you to install a 4-way connector part # 118786 which provides all of the trailer lighting functions and then convert to a 7-way with the part # ETBC7 which the 4-way plugs into and comes with everything needed to wire up a brake controller. I attached an install video for this kit on a similar 2012 Jeep Wrangler Unlimited as yours for you to check out as well. For a brake controller I would recommend...

  • Will The Curt Flat Tow Harness Also Work With Tekonsha Tow Harness on a 2023 Jeep Wrangler JL?
    Yes, the Curt Custom Tail Light Wiring Kit # C96JR will also connect with the T-One Vehicle Wiring Harness # 118786 on your 2023 Jeep Wrangler JL. These all use the same style factory connectors so they will plug in line of each other. If you have any additional lighting connected to the trailer connector on your Wrangler you will need to ensure you connect the Curt harness to the factory harness and then the Tekonsha trailer wiring into it then the tail lights so they get the power needed...

  • Is 3.6V on 2020 Jeep Wrangler Unlimited Trailer Plug Abnormal
    If it's just a 4-Way Flat connector like the T-On # 118786 then I would be surprised to see that much power being pulled to the back of your 2020 Jeep Wrangler Unlimited, but if you have a 7-Way like what we find with the Wiring Kit # ETBC7 then 3.6V on the 12V power pin isn't out of the ordinary and you'll be fine. Attached are photos showing the functions per pin on both a 4-Way and a 7-Way connector for you to reference.

  • Is The Tekonsha T-One Vehicle Wiring Harness # 118786 Made With Solid Copper Wire
    Hi Bob, No, most if not all trailer wire harnesses, including the Tekonsha T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786, are made of stranded copper wire. The wiring typically has to pass through tight areas and be able to easily bend so stranded wire is the easier and more cost effective option over solid wire.

  • Will Installing Trailer Wiring Harness Void Warranty on 2019 Jeep Wrangler
    That is a great question. The good news is that consumers are protected by the Federal Magnuson-Moss Warranty Act. This act essentially states that if something were to break or go wrong on your Jeep and you take it in for warranty repair, the dealer must honor the warranty regardless of what modifications have been made unless the modification is what caused the issue. Installing an aftermarket wiring harness like the excellent Tekonsha T-One # 118786 yourself that you referenced will...

For this route on your 2021 Jeep Wrangler without a factory tow package, I recommend using the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118786 along with the Curt Trailer Connector Adapter - 4-Way Flat to 5-Way Flat - Vehicle End # C57187.

  • How to Install a Trailer Wiring Harness on a 2019 Jeep Wrangler
    Yes, the installation of a trailer wiring harness will be different for a 2019 Jeep Wrangler MOAB when compared to a 2013 Jeep Wrangler MOAB but not by much. Instead of just plugging in one connector behind the driver side tail light you will need to plug in a connector behind the passenger side tail light as well, run a power wire to the Jeep's battery, and ground the harness to a bare metal surface. For the above, I recommend using the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer...

  • 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...

  • Troubleshooting Fuses Blowing on 2023 Entegra Odyssey Class C Motorhome Towing Jeep Wrangler Sport
    Hi Bruce; more than likely you can rule this out as the issue. The T-One Vehicle Wiring Harness # 118786 has the ModuLite Power Module which draws power from the vehicle battery so it won't be overloading any circuits on the motorhome that would blow a fuse. If you didn't have a powered module I could see it being a problem but that isn't the case here. I'm assuming you didn't start blowing fuses until you installed the trailer wiring which is why you're looking at it as a potential issue....
