Radio Illumination
When the parking lamps or headlamps are ON, circuits E2 and L7 from the headlamp switch power the radio illumination lamps. Fuse 20 in the fuse
block powers circuit E2 which feeds the radio illumination lamps. Circuit E1 from the headlamp switch supplies power to fuse 20.
Circuit L7 supplies voltage for the radio park lamps. The radio case ground completes the illumination and park lamp circuits.
