4-Way Flat Vehicle Wiring Harness For a 2021 Mazda CX-30

Question

Question:

I installed 3 of these Curt kits on my 2021CX30, this kit is NOT compatible. Power is sent to both turn signals when you put either turn signal on. Brake lights and Hazard lights work correctly. Kits were professionally installed and tested. Video results sent to Curt. Any suggestions on another brand for my 2021 CX30?
