Trevor, I'm gonna CN your 100% correct text real quick here. Our current circuits:
+12 - HEADLIGHT FUSE - HEADLIGHT RELAY - FOG RELAY TOGGLE - FOG SWITCH - HI/LO BEAM SWITCH - GROUND
+12 - FOG BULB - FOG RELAY - GROUND
You're basically looking at an "AND" - the fog switch and the hi/lo beam switch both close the circuit together. Kid stuff.
So, how to throw an "OR" into the works?
...PARKING LIGHTS - FOG RELAY TOGGLE - FOG SWITCH - HI/LO BEAM SWITCH - GROUND
+12 - FOG BULB - FOG RELAY - GROUND
Not much to change there! Is there any reason that changing the (low current!) source shouldn't work?
