So I am curious on the 4th picture (the one of the finished wiring). And I have seen it both ways so curious as to people's perspective which is the inclusion of a fuse block like the Blue Seas I see in the picture, and the fuses on the switch panel itself. Some folks maintain that if you have switched panels (fuses) you don't need the fuse block unless you are running something that is not included in the switch panel while others have both, as I see in the picture. It appears as though most diagrams show one connection into the fuse block from the switches and the house equipment gets both positive and negative from the fuse block. Which I don't understand. Hopefully this makes sense, just starting on re-wiring my boat and trying to understand the role of the switch panels and fuse blocks.
