They are not exactly schematics, but here's a link to the wiring diagrams for your 2019 View 24J:

I can find the solar panels, the controller wiring and the battery wiring, but unless I missed it I don't see exactly where the wiring from the solar charge controller attach to the batteries.
This diagram does show the wire colors to the batteries. I think it says it runs to the chassis electrical panel. On my totally different motorhome, they run directly to the battery posts.
