As far as I know, there is no diagrams for the electrical, and plumbing systems.

You have two gray water tanks and two black waste tanks.
Looks like the main bath has one of each
the kitchen sink and bunk bath share a gray tank
and the toilet in bunk has the other black waste tank,

If that's not correct you could call Heartland customer service. Have Vin # ready
