Sorry if pedantic and absolutely no criticism intended. It should be obvious but, to the uninitiated..., Craigs super helpful photos show the flap wheel to clean up the hole prior to the one drilling it with the hole saw.
Also Rob’s advice: on mine, to remove the dash for access, I would also have to remove the series of little screws that attach the undertray to the edge of the dashboard, as well as the three main securing screws.
