Older wiring diagrams are hard for me to read. In the diagram, the brown wire is voltage for tail lamps, the black wire is ground, the other wire is voltage for brake and turn. Brake and turn use same bulb filament, just not at the same time, they are wired through the turn signal switch. Did you check all applicable fuses, bulbs and bulb sockets. I'd have to check those wiring circuits to find out what is going on.
