Wiring diagram for lights...

It's set up for reverse lights, but it doesn't really matter WHAT kind of lights you use. Just remember that for driving/fog lights, tap into the parking lights and use that power as the trigger for the relay (this is the wire with the switch in it in the diagram). That way, you can't turn on your driving lights unless the parking lights are on. That will also prevent you from leaving the driving lights on and draining your battery (you'll get the "lights on" warning/beep if you do).

If you need more, let me know and I'll help.
