MECMO56407 4-Pin Trailer Wiring Harness for 2018-2025 Jeep Wrangler JL/JLU, 2020-2025 Jeep Gladiator JT, 19-25 Wranglers Unlimited, Rubicon, Sahara, Sport, 4xe Towing Hitch Wire Trailer Light Plug

Worked great, easy install nice kit. I'll update if anything changes

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.

Easy install but had to extend the green wire as it was a bit short.

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 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.

Easy to install.

Fit with no issues. Works great

I bought the product 6 months ago but didn't get around to installing it, now the warranty is expired. Brand new out of the box I went through the installation and the passenger side tail light did not work. I removed the plug-in adapter and hooked the tail light back up to factory and it worked fine. I did check the plug for bent pins and did not see anything, tried plugging it back in and nothing worked.
