I'm not sure why you didn't get a seperate book of schematics, Robert. One came with our '06 Monterey, as it apparently did for many other Beavers. Perhaps you bought your coach used? It seems to be common for used rigs to have lost their original documents, though I've never understood why people would ever take them out of their rigs.
One great thing about this Forum and the BAC is that members are willing to provide copies of their schematics and other documents when a fellow member needs them. There are quite a number of '07 Contessa owners here, so if you ask the next time you need a schematic, one of them would probably be happy to scan what you need and email it to you. They likely will need to know your floor plan, though, because our book, at least, has schematic pages for multiple floor plans.
