Mattax noted that the FL on the alternator side would not be really necessary, but that it would be better to have a 16 gauge FL on the battery side, at the starter relay, to better protect the 16 gauge wiring in this system.
I saw your idea on the quick disconnects that you are going to put in your car, over on the other forum. I like that, and will be looking for a set of this wiring for my truck. I like your last diagram, and think this is what I will put in my truck.
