Thank you. It appears you have done the research. I will look into the required system.No electric brake controller on ANY Palisade; you'd have to buy one... along with the Kia harness. I have a 2021 Calligraphy too, and all you get is the rear leveling shocks, and the extra cooling capacity. And of course the empty connectors for the trailer lights at the back, and the brake controller in the front.
Everything else tow kit, harness and 7 pin installed. I will have to figure out the braking piece of the equation. Thanks again.
