lol, i think he wanted how to do it - not just a simple yes or no, heh.
Anyways, its electrical work. I'm no electrician nor have i tried it on my car - but all it would involve is locating the wires for headlights/foglites and a little re-wiring.
all one needs to do is to disconnect the current 'source' wire at the fog light switch (the wire that does not go to the bulbs) and run a new source wire from a key-on 12 volt source or from the parking light wire (if desiring to only have the fogs be able to be on with parking lights).
i would add a SPDT relay at the same time to help out the wiring (though you will not be running power through the headlight circuit anymore, even without the relay (note:be sure to choose a circuit that can handle the extra power draw of the fogs if not using a relay. the stock fuse on fogs is 15 amps). i would do the relay upgrade at the same time, myself.
