I didn't like that the headlights needed to be on to run the fogs. I first rewired them to be switched on with ign. hot. Then, I installed some nice square Pilot Fogs it the stocker place. It was easy to rewire the org. switch, but I later upgraded to lighted rocker switches in the center console near e-brake handle. If you want to run independently from headlamp switch, find what wire is hot at switch and run new power from key-on accessory. It has been years and I can recall which wire; a test light is your best friend in this situation. I ran power from the rear defroster switch(rarely used and plenty of amp capability even without relay).
