The Curt Wiring Harness with 4-Pole Flat Trailer Connector item # C56377 for the 2022 Mazda CX-5 attaches behind the rear tail lights. You will have to take apart your cargo area to remove the trim pieces to access the tail lights. The T-one harness plugs in line with the tail light harness so you won't have to cut or splice any wires. I have linked a video that shows the entire installation process including the removal of all cargo area trim to access the tail lights.
