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.

This was an easy to install wiring harness for my 2025 Jeep Wrangler. It plugs into the existing Jeep connectors so no wire splicing. My only complaint is the wires are not enclosed in wire loom and no bracket for the 4 pin trailer connector. I can't imagine it would add maybe $10 to the price.
Greta place to buy your trailer items. I ordered a complete wiring kit for my sons Jeep JL. We had everything we needed and I called a few times with questions. The person at etrailer talked me through the questions.
I have also bought trailer tires there with excellent results.
I installed this on a 2024 Jeep Wrangler Sport. Everything was as described in the installation video except l could not fish the passenger side wiring harness through the frame because a connector was too large to fit through the existing frame openings. I also could not fish the power wire through the frame to the battery due to very limited access to frame openings. Instead l placed the wiring in wire loom as recommended and zip tied it on top of the frame members. Everything is secure and works great. Thank you for your instructional videos and excellent service.
Overall good and relatively easy to install. I was installing on a 2025 Jeep Wrangler. I had to cut and reconnect the green wire so I could run it through the frame. Also, I used some fish tape to go from the back to the front of the vehicle, to run it through the frame. I tried to feed the wire through the frame, but access and the curvature of the frame near the back axle required something a bit stiffer. I’d probably say it’s a 4.8, due to slight difficulty of install, but the product works great.
Pretty straight forward install if you watch the video when installing. One comment, I found wiring through the frame extremely cumbersome so I installed along another string of wires above the frame. Be sure to buy the mount they sell separately.
I was extremely pleased with the customer service I received before my purchase. I wanted to ensure I was getting exactly what I needed. Very pleased with my purchase and the customer service. That is rare these days.
The hitch went on easy the wiring a little bit of work feeding through the frame but not bad at all that’s why I like these trailer hitch with the videos makes it nice and easy I appreciate it that very much
Easy to install, hot wire attached to lug on side of fuse block w/fuse.
Use 4' flex rod for electrical to fish wire to fuse block under vehicle
No problems simple installation plenty of help on line or by phone great customer service thanks
Fantastic absolutely awesome from ordering that was so easy and direct to the lightening fast shipping definitely ordering from here again and again
Great product and awesome installation videos
very easy install and good instructions
Another successful order and install from etrailer.com! Always fast shipping and excellent installation guide videos! Installed on 2021 JL Wrangler EcoDiesel.
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.
It is so easy ordering from eTrailer. Randall was excellent in helping me with the right parts to order.
Great product. Easy to install. I ran the wire through the frame to the battery. I used a feeding fish line tool and you cant see the wire from the rear to the front.
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!!
Everything bolted right up and the electrical was easy to install. Very happy!
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.
It was hooked up by mechanic without a problem.
we never got to use it, because we decided not to tow a vehicle behind our RV,
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.
I made this purchase after watching the installation guides on YouTube. I'm not the most experienced "car guy", but everything went in super easy. I'm really satisfied.
EVERYTHING CAME IN GOOD CONDITION AND WORKING ORDER...
YOUR VIDEO ON HOW TO INSTALL THIS WAS GREAT !
Received it fast,in a good sealed box.Did not install yet but based on the reviews,should be a good product.
Fast shipping great products
