I live on the coast so fog is a constant issue. On my '05 Sport Trac I had PIAA 5 inch fogs on their own harness and their own switch stuck on to the dash. For my 13 XLT I want to add some lower profile rectangular fogs in front but would like to wire them up to come on when I activate the built in fog lights. Can this be done using the harness that comes with PIAAs (usually a power line, a relay, and a switch) or has anyone done this? I'd like to avoid additional buttons stuck on my dash.
