TERMINALS
-
1. Connect the LED + RED 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.
2. Connect the LED - BLACK terminal to chassis ground.
