Find the hot lead for the fog light relay that comes from the headlight relay. Cut the wire (with enough slack to splice), and splice it into a lead that has 12v power with the ignition on only. This way the lights cant be left on and kill the battery. I don't remember the exact leads I used as it was 4 years ago. Basically, this will power the fog light relay anytime the switch is on regardless of the headlight status. Hope this helps.
