Rosette: Slide the long end of the mounting block through the baseplate of the rose and screw the plate back on the door with the original screws. Push the mounting block into the door so it's flush with the baseplate so you can place the faceplate on.
If the you don't have an anti plug pulling feature, place the faceplate back on the baseplate and slide it to its final position. Guide the cable of the outside module through the opening in the mounting block and through the door until the module is flush against the rose.
If you do have an anti plug pulling feature, guide the cable through the faceplate, mounting block and door before placing the the faceplate on the baseplate and sliding it into place.
