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.
