The schematic for the A/C is on pages 97-137&8 in my Bently (July 15th,
1991).  It has all of the parts listed in the diagram.

According to the schematic, there should be a red/white wire from fuse
#7 that goes to the radiator fan switch, and to the radiator fan relay,
on factory A/C vehicles. On non-A/C models, fuse #7 still controls the
fan relays, but the wire is solid red going to the fan relay, and
red/black going to the fan thermoswitch (radiator).  The wiring is
different on the A/C models to allow for a two-speed fan. Also, if you
have dealer-installed A/C (as opposed to true *factory* installed), the
Bently is not necessarily going to be accurate insofar as the wiring of
the fan switch, A/C relay, and load reduction relay are  concerned.  On
my '86, with dealer installed A/C, all the +12V feed wires, to the above
mentioned components, are solid red.

The wire from fuse #6 should be a white/black wire right side low beam
headlight. Cabin lights should be fed from fuse #8, and I don't see any
evidence of speaker connections in the schematic at all (starts on page
97.54).  Good luck!
