Here's some pics of the "working" system. I'll probably clean up the wiring a bit when I re-make the harness for the lights/horns/etc and incorporate the AC wiring into that harness.
I also decided to use a Billet Specialties dual bulkhead connector on the firewall instead of holes with grommets. The location is where the stock heater control valve was located so I made an aluminum plate the same size as the valve and put the connectors in it. I then spliced an external heater control valve (from a Peterbilt truck) into the heater hose and will run the cable from the heater control to the new in-line valve.
I'm toying with the idea of doing a complete re-wire with an always hot bus, switched buss, panel light bus, and ground bus with each circuit taking off from it's proper bus. Thinking about two different fuse panels - one for switched and the other for hot.
