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.
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.
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.

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
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.
Wiring working excellent on my 23 Jeep Gladiator. Great company to deal with, you can't go wrong
The harness came with great and simple instructions. I was easily to install it and it works great! Thanks for a great product and I highly recommend it for anyone looking to put a trailer harness on their vehicle.
Exactly what we wanted, hitch was very easy to put on. Very quick arrival. We ordered a wrong harness snd customer service was very quick and courteous to help us get a return label.
Would highly recommend this company.
Fairly easy to install as long as the vehicle is up on ramps or even better would be a lift. I used ramps and crawled the length of my jeep to run the wires to the front and secured them to the frame away from heat or pinch points.
Was easy to install, compatible with the factory plugs on my Jeep Wrangler. Aftre 1 year of use it’s woking god.
Great harness that installed easily following video instructions.
Product works well with my 2022 Jeep Wrangler 4xe. etrailer was great in helping to ensure that this product would actually work with my Jeep. Thank you!
The wiring harness was made of high quality parts and very easy to install. It had all the hardware need to wire it in correctly.
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.
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.
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!!
Simple. Assembly received complete. Works well.
This wiring kit was just what I needed to get trailer light connection on my 2021 Jeep. I have been very satisfied with all of my purchases from etrailer!
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.
Had exactly what I needed to wire my Jeep up for trailer lights. Very quality wiring harness and easy to follow instructions. They ship very fast and keep you updated on where your package is. Highly recommend etrailer!!!
Customer service was excellent in getting exactly what we needed for first time installation. Thank you.
Very easy install. Etrailer was very easy to deal with. Very quick shipping!!!!
Super easy install
Good quality, easy to install, work gre at.
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.
great products and service
Delivery was super quick, ill let u know how the install went later. Thanks

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.
