Black tank flush connections

[Retired Pyrate]

Are both of the circled inlets black tank flushes or just the one on the left? 2018 3920FB with two black and two gray tanks. I know for a fact the one on the left with the green hose flushes the rear, half bath black tank only. The labeling above the right makes it seem it’s a fresh water fill, but I’m not so sure. Hopefully the pic attached correctly.

There should be just the one fresh water connection. Being there is only one fresh water tank. I would hazard a guess that the two side by side are black tank flush connections.

The one circled on the right is the black tank flush for the front bathroom with the tub.

Bath and tub would be gray water and not needing a flush.
Second toilet (black tank) would get a flush connection.
