Helpful Expert Reply:
The Curt Upgraded Circuit Protected Powered Tail Light Converter # C59496 will splice into the wiring behind the tail lights on your 2019 Hyundai Tucson. You'll likely need to open the rear hatch of your Tucson to access the area behind the tail lights; there should be some screws that allow you to remove the tail light housing and access the wires you need to splice into. You will also need to run the included heavy gauge wire to the battery and connect via the included ring terminal.
Connections to the wires will be made as follows:
Yellow: Left Turn
Green: Right Turn
Brown: Tail Lights
I have linked a video installation of a similar wiring harness on an older Hyundai Tucson, but the process will be quite similar. I've also linked the instructions for this harness that you may want to have a look at as well.
