Ed, the picture of the black switch panel (with AC on left) is mine The picture of the brown switch panel (with the AC on the right, like yours) is Phillipe's. My wiring was tidy, but Phillipe definitely raised the bar!
I installed a Blue Seas MAXI Fuse Block with an 80A fuse just below and to the right of the main battery switch (less than 6" wire length away).
A bit of trivia: You may notice the small, in-line fuse holder coming off the MAXI Fuse Block - that is the "unswitched" brown wire that goes to the bilge pump. Of course it is, in fact, switched by the main battery switch.
