    You can not hook the fogs directly to the headlamp circuit. You'll overload it and blow fuses all day long.

    You need to use a relay and power them off of the battery, using the low beams (or parking lamps) as the trigger source for the relay.

    Most 30 amp automotive relays have 4 poles....#30, #85, #86, #87.

    Wire it up this way:

    #30 (+) to battery with a 15 amp fuse as close to the battery as possible.
    #85 (+) to low beams or parking lamps.
    #86 (-) ground
    #87 (+) lead to foglamps

    If you want a switch to defeat the fogs completely, just place it on the signal wire (#85).
