ILLUMINATION WIRING:
Option 1
- Connect the LED + spade terminal to an accessory switched 12 volt wire. This wire should have +12V
when the ignition key is “on” and 0 volts when the ignition key is “off”. You can use a toggle switch
in line on this wire to manual turn the illumination off if desired and this 12V+ wire must have a 5 amp
fuse in line.
Option 2
- Connect the LED + spade terminal to the Radio / CD player “remote out” wire which is also connected to
the amplifier “remote” input terminal. This ire will show 12 volts when the radio is “on” and 0 volts when
the radio is “off”
Connect the LED - spade terminal to chassis ground.
