Works great
Easy install and works perfect
JFINK –
Good value for the money
A really goodbye for the price. It was pretty much plug-in play, and there was plenty of wire to go from the back of my Jeep to the front where the battery is. Not the high-quality I could get from Jeep Mopar, but it does the job well

Works great on 2018 Rubicon but had to extend the green wire as it was a little too short
Easy install but had to extend the green wire as it was a bit short.

Easy to install, works great so far
I bought this to replace another aftermarket trailer light harness. I have a 2019 Jeep Wrangler. This fixed the issue with the Canbus system in the Jeep.I have LED trailer lights, due to the low power consumption of the leds my Jeep thought the light bulb (usually incandescent) was blown.When this happens the Canbus system slowly pulses the lights it thinks are out as a warning.This box fools the Canbus system into seeing the full draw of an incandescent light bulb.This allows full voltage to pass thru and into the trailer lights.I already had the power home run to my battery. All I had to do was swap out the T connectors and run the green wire and T connector to the passenger side and connect.

Itâs good. A bit involved but good

Works for my 2023 Wrangler 4xe
Fairly easy install considering most parts are plug and play, and running wires around the frame. The only hard part/time consuming was running the ground wire from the rear and going through the framing underneath the car to reach the engine bay. I wanted to make sure the wiring looked clean, protected from debris and avoid catching anything underneath while on the road, and away from the exhaust.Google âetrailer for Tekonsha T-Oneâ for a walkthrough video. That wiring harness is pretty identical to this kit, which helped me a lot.The new plug that connects to the tail lights doesnât click/lock in as smoothly as the OE. Have to give it a bit more force to snap in and lock, while being careful to not break anything.I do not have a trailer yet, but I purchased the Oviny 4 Pin Male and Female Tester here on Amazon. Everything lit up as it should. Glad to know itâs ready for if I ever need to tow something in the future.

Garbage
Horrible. Spent hours to connect and didnât work. There are so many other options that are easier to use. And yes, I connected it correctly. Also, no instructions to remove the 09 fuse before disconnecting the negative terminal on the 4xe. Just a garbage product.
Amazon Customer –
For someone with little luck or experience with electrical stuff I found this install to be quite simple on my JL. The biggest job was neatly running the power wire from the battery to the drivers-side taillight.
Aaron Condon –
The product looks great however it does not fit the Jeep Gladiator as advertised. The inline connectors for the rear tail lights are incorrect and do not connect to the Gladiator connectors.
