Anyone have a 93 25' Barth Regal that could tell me how many cables are on the pos. side of the chassis battery?

I believe I may have figured the question about the Pos. battery cable off the 80 amp Breaker should go to the house batteries as I think or the chassis battery? I have myself in a overthinking mode and need peace of mind.

The circuit diagram shows that there are 2 of the 80A breakers, and neither connects to a battery.
