Corbeil Bus Electrical Schematics
The good folks at Collins Bus Corporation (the people who bought Corbeil) were kind enough to provide me with the schematics for a 2000's era Corbeil Bus, including their Multiplex system. If this information would be helpful to anyone else, please let me know and I'd happily share. The biggest issue is that not all of the magnified sections are full-color. The full schematic is full color, however, so it shouldn't be too much trouble to flip between the two to figure out what color wires to anticipate.
