Great quality product and installation is super simple. Mostly plug and play!! ### ⭐⭐⭐⭐⭐ It's as simple as it gets *by K***C on April 7, 2026* Everything went together nicely the only problem is getting your power line from the back bumper to the front. I suggest follow the frame on the driver side all the way up to the master cylinder and then across to the battery ### ⭐⭐⭐⭐⭐ Works for my 2023 Wrangler 4xe *by X***N on June 22, 2023* 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. ## Frequently Bought Together - MECMO 56407 4-Pin Trailer Wiring Harness for 2018-2024 Jeep Wrangler JL/JLU, 2020-2024 Jeep Gladiator JT, 19-24 Jeep Wrangler Unlimited, Wrangler 4xe Towing Hitch Wiring for JL Trailer Light Connect - YZONA for Jeep Wrangler Tow Hitch Trailer Kit Compatible with 2018 2019 2020 2021 2022 2023 2024 Jeep Wrangler JL JLU Hitch Receiver with Cover, 2 Inch Rear Bumper Towing Combo (2 Door & 4 Doors) - MECMO Multi-Tow 4-Way Flat to 7-Way RV Blade and 4-Way Flat Female End Trailer Wiring Adapter Connector Kit, 4 Pin Vehicle-Side Trailer Light Plug to Dual-output 7 Blade & 4 Flat with Mounting Bracket --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/471580558-mecmo-56407-4-pin-trailer-wiring-harness-for-2018-2025](https://www.desertcart.hr/products/471580558-mecmo-56407-4-pin-trailer-wiring-harness-for-2018-2025) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-22*
