It's a good question, and good luck, but I've not found a much luck myself as I"m restoring as well. I think the best option is to start with what A/S provides. You can dwnld the electrical schematic and adjust to your needs. You still need lights, inverter, etc. and those items are all in the factory schematic that is available. I've seen them posted in a PDF on these forums somewhere. Luckily mine '73 came with the service manual. Even though mine is 100% gutted, again, it's a decent starting point...
