This probably does not help much since my Vista is a different size and year, but our "Ship System" breaker is located in the same panel as the battery switches (starboard side of boat above engine hatch covers) and it does control power to the boat's 12 volt system. Still need to turn the 12 volt power breaker on in the galley's electrical panel in addition to having the "Ship System" breaker on to run your 12 volt items.
