where are you in coastal Ga? I'm in Savannah on Wilmington island. I have done some wiring (I'm not a professional), and everything worked when I hit the switch the first time.
I will recommend Deep blue Sea Systems hardware. That is Pos and Neg Busbars. Oh, I'll try to find ya the links to what I bought....

I hope this helps you out. I've done the research for you.
As far as the young'un, you're on yer own.....
