The U-Haul SmartConnect Trailer 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. U-Haul SmartConnect 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 shouldn't void any warranties and can be done in as little as 30 minutes! Unlike standard aftermarket wiring that only transmits basic lighting signals, the U-Haul SmartConnect 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, U-Haul SmartConnect Trailer Wiring™ automatically disables rear backup sensors so that your vehicle can move normally.
The SmartConnect series is exclusive to U-Haul, so you will not find this functionality at this low price anywhere else!
This ATM4002A trailer wiring harness kit is compatible with the Hyundai Santa Cruz (2025-2026).

Installed this a few days ago. Lights work, but get constant error messages and warning on the dash when the 4pin is plugged in. One message keeps telling me trailer attached. At times get messages stating verious lights not working, when all are working. What needs to be done to fix this. ATM4002A.
