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.

Another successful order and install from etrailer.com! Always fast shipping and excellent installation guide videos! Installed on 2021 JL Wrangler EcoDiesel.
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.
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.
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.
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.
Ordered the wrong one had to return it. Customer service very helpful

once i got the right one it has worked great no problems
Good quality and clear instructions. This is so much better than the old days of splicing into the harness.
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!
Everything needed was included, products after a year - so far so good.
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.
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.
