I had to bring it home and put it together to get some more debug information. Based on my initial investigation I think the harness is not compatible with North America LC200 which has a JBL amp system. I did some research and Joying provides the correct harness Toyota Prado Power Cable For Toyota Cars With JBL AMP - https://www.joyingauto.com/toyota-prado-power-cable-for-toyota-cars-with-jbl-amp.html
I still haven't heard back from the support. Adding some pics on assembled unit. Will add more pics of the system attached to the car.
