More Wiring Help

[benhardj]

I've got my switch panel, battery isolator, battery switch, fuses and I'm ready to start running wire. What sizes and types of wire will I be needing from my battery switch back to my batteries and forward to power my electronics and lights.
I should let someone who knows what they are doing do this, but there's no money left!!
Thanks for all of the help on my last post.
