At this point, You will probabaly have to change your wiring diagram again as you will see mistakes that you made. Now take this spec'd out wiring diagram to your boat and actually measure out each wire to insure that you have enough wire for each run, don't skimp on guage or the bells and whistles, like GFI and AC breakers . Now go to a big marine store and buy everything, don't scrimp, if you do it right you won't be doing again, having it light your boat on fire, electrocuting a guest, or turn your boat into a big pile of metal oxides). You also need to pay attention to the sections in the books about "stray" currents and galvinization. If you are in an area where there are other boats hooked up to shore power, you might want to look at their boats to make sure that they are hooked up correctly.
