Ken, do you really want a buzzer??? Seriously, take the wiring diagrams
with a grain of salt. Different configurations were used for different
markets on a given year and the phase in of features occured at any point
during a model run so you pretty much have to look at all the digrams and
fend for your self.
The light should mount in a metal bracket spot welded to the underside of
the dash just right of the steering wheel. This bracket has a hole in it
for snapping in a typical bulb holder.

The purple wire is fused-always hot and is typically used to power the
curtesy lights. The 71 had a single curtesy light mounted at the end
(rear) of the driveshaft tunnel. If that piece is missing (DPO?) then this
might be the power feed for that lamp and the boot lamp. The door switch
uses only one wire as the switch will earth the low side of the curtesy
lamp and the other side is connected to the purple wire.

Perhaps it is the green wire to the turn signal flasher which would explain
why the signals don't work. (another thing to check is the emergency
flasher relay)
Speaking of turn signals, the fuse that feeds the signals also feeds the
brake lamps, the wiper motor, the gauges, and the heater. Check the
opertion of these items.
