Ok...so there should be a single 12V switched IGN lead that "turns on" the alternator. Then, you should have at least an 8ga (or larger) main charge lead going to your main firewall junction. From that point is where you need to make ALL of your power runs. With everything you've got going on, I'd say you should have a 4ga main supply charge lead. Do you have any detailed engine bay pics?
