My truck did not come with fogs.
I removed the bumper (there's one tricky clip on the sides, PIA)
I picked up some really nice high power LED fog lights from my local auto parts store for around $30 OTD.
The stock bumper black dummy fog blanks have 2 screws on the back and pop out in a perfect circle(no cutting) that accomodates most medium sized fog lights (4"?)
I grounded them and tapped into the DRL.
