I removed the rear seat cushion to access the battery . When I put it back together I noticed one of the seat belt buckles looked different then the others . Low and behold it was a U.S.B. port . Son of a gun !
Forget I said anything ! Totally disregard ! It is a buckle of some kind . Looks very close to a U.S.B.
Yeah. The buckle for the rear centre seatbelt “base”. It’s there so that you can detach the rear centre seatbelt when you fold the rear seats.
