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.

The wiring worked.Then it stopped.I investigated and found a melted wire.The fuse at the battery did it's job and blew tho.Still I took it all off for safety.Maybe I got a lemon..

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.

The 4-pin wiring harness for my Wrangler JL was a good purchase overall. The installation process was relatively straightforward, although the provided instructions were not very helpful. Instead, I relied on a YouTube video that guided me through each step. Despite having no prior wiring experience, I found the setup manageable with the video tutorial. The harness works well and has met my expectations for functionality. I would recommend this product, but be prepared to seek external help for installation.

This was relatively easy to install, I wish they would include a double wire +/- but that fine. I ran this up to my RC MLC6 and it works perfectly.

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 “etrailer for Tekonsha T-One” 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 doesn’t 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 it’s ready for if I ever need to tow something in the future.

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.
