The Advanced Trailer Module (ATM) wiring harness kit from U-Haul combines lower cost, easier installation, and OEM-level functionality into a single 'smart' towing solution. It’s designed for drivers who want factory-level performance without paying dealership prices. ATM trailer wiring uses easy plug-and-play connectors that tap into factory connection points. There's no cutting or splicing, so it's a cleaner, faster installation that can be done in as little as 30 minutes! Unlike standard aftermarket wiring that only transmits basic lighting signals, the ATM trailer wiring kit communicates with your vehicle’s high-tech sensors to ensure full compatibility with modern safety systems. For example, when a trailer is connected, the ATM automatically disables rear backup sensors so that your vehicle can move normally.
This ATM4001A trailer wiring harness kit is compatible with the Hyundai Santa Fe (2024-2026), Hyundai Tucson (2025-2026), Hyundai Ioniq 5, Kia EV9 (2023-2026), Kia Sportage (2025-2026), Genesis GV70 (2025), and Genesis GV80 (2025).
The ATM series is exclusive to U-Haul, so you will not find this functionality at this low price anywhere else!
Stellar installation procedure with all necessary materials included. Only a phillips head & flathead required (for removing trunk tray). Integrated easily with vehicle .

This was amazing! So simple to install and worked first time exactly as advertized and a great price. Not only did the lights work, the interface with the Hyundai interface and dashboard was also perfect!

Plug-in trailer wiring harness extremely simple to install as advertised and at a decent price. Worked perfectly the first time with no problems. Can keep harness inside vehicle as I wanted for weather protection. Absolutely the best harness I have ever had.
