I have followed the thread on wiring and just thought I would add this.

     I wired the switch to a relay that takes power from the alternator/battery through a 30 amp fuse.  The relay gets power from the "G" single connectors on the back of the fuse panel.  This is 12Vdc switched by the ignition.

     I wired the fog lights on an independent circuit so that if the head lights failed, I would have an alternate light source.  This setup has saved me on a trip through the Ozark mountains.  The switch for the headlights failed.  I was on a winding mountain road, when suddenly it went black.  I switched on the fog lights and was able to get to the next town and make temporary repairs to the headlights.  Wiring into a circuit switch off by the ignition will prevent battery run down from leaving the fog lights on.  

     I have also wired the head lights through a relay to prevent another failure of the headlight switch.  The headlight switch is wired through the OEM fuses and switches the relay.  The relay draws power from the alternator/battery.
