Hello David, thanks for reaching out. Currently there are no custom fit wring options for the 2025 Hyundai Santa Cruz at this time. Our best option for a wiring harness will be the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT. This uses clamps that go around the wires and detect electrical pulses. This way you can add trailer wiring without cutting or slicing any of the vehicles wiring.

Leave a reply with and questions or comments and I will get back to you.
