Hey Greg. We'll have one as soon as Curt or Tekonsha make one for your 2025 Hyundai Tucson that actually fits. I just checked their websites and they do not list anything custom fit.(09/15/2025)

The only option I have for you is the Curt T-Connector Vehicle Wiring Harness item # C28DQ. This is a universal harness that uses clamps instead of splicing. These clamps attach to your tail light wires and sense the signals being sent through them. This is sent to the 4-way connector to activate your trailer's lights.

What kind of trailer do you have or are you needing lights for an accessory like a bike rack or cargo carrier?

Boat/Utility trailer; 4-way connector for the lights.

@GregoryL I know the universal harness item # C28DQ is not the solution you were hoping for but it will allow you to control your boat trailer's lights. Custom fit Hyundai and Kia wiring harnesses have been a point of contention for the last few years because the manufacturer's keep changing the connectors they plug into behind the lights.
