I'd suggest upgrading the wire size from your buss bar to the fuse box and maybe adding relays for your headlights. The headlights are easy to wire from your buss bar to a relay using the original low and high beam power wires to trigger the relays. The other point mentioned above is the bulkhead connectors. Resistance causes voltage drops and heat. I've seen connector plugs that have melted from poor connections. Any other accessory you can power from a relay will take stress off the rest of the harness. I'm a big fan of madelectrical.com - lots of good information.
