There are TWO connectors. One goes to the turn signal switch, the other goes to the ignition switch, and both have a brown wire.

The brown at the ignition switch is hot "in start" goes out through the bulkhead and feeds the coil+ side of the ballast resistor. This is the source of ignition voltage "in start."

The brown at the signal switch is going to the right rear stop/ turn filament
