if you don't have backup sensors, put the plastic plugs in the outer two holes on either side. If you do, put the rubber grommets in those holes instead. When installing the sensors, it may be necessary to cut a small slit in the harness loom in order to be able to separate the sensors enough to install. Be sure to seal everything back up with something like electrical tape.
This is the best time to install cube lights if the plan is to do so. Some lights will fit through the cutout after the bumper is installed but they will no longer be able to be installed from the inside.
