He removed the plug covers to be able to remove the rear plastics.
Whenever I work on the back of the scoot, I remove all of the red pieces as a single unit. It takes all of 5 minutes to remove all of it. I remove the met-in and seat as one piece, removed the license plate and then all of the red back of the floorboards come off as one big piece. Very simple. That being said, I didn't know the re were covers... never had them on my scoot. I bought it used and they were not there.
