Unless the documentation was a LOT better back then, I don't give much for your chances. As I understand it from what other members have posted, things are wired up to a factory schematic without any regard for wire color codes.
Also, if my experience with FR Georgetown is any measure, the "Owner's Manual" is so generic that it's only good for lighting your campfire.
