Radio, Stereo, and Compact Disc: Description and Operation

The Radio receives voltage through four paths: 1) RADIO Fuse to the On-Off Switch from the YEL wire; 2) CTSY Fuse which keeps the solid state clock, date, and the Radio station memory circuits alive when the Ignition Switch is turned OFF (ORN wire); 3) an Instrument Panel light voltage controlled by Panel Light (GRY wire); 4) a Digital Dimming voltage from the Light Switch (BRN wire).
The Radio OFF-ON Switch also applies battery voltage to the PNK wire to operate the Power Antenna.
