86-89 schematics shows the two mirror map bulbs get power from the Gages fuse.
When the ignition switch is in Run and the rocker switch is on,
the two lamps should light.
The other bulb hidden behind a slit on the bottom edge of the
mirror is the console illumination bulb. It lights when the headlight
switch is in Park or Head and dims with the dimmer switch.
The driver and passenger door map lights do get 12 volts from
the Ctsy/Clk fuse. The two lamps are inset into the door panels.
To eliminate the radio, you need to unplug the two wire plug
on the back/right side of the radio. Usually a Brown wire and
and Orange wire (could be Pink/White). The Orange or Pink/
White wire comes from the Ctsy/Clk fuse and supplies 12 volts
for the radio memory and Clock.
