Just buy some aftermarket fogs.
Many come with a switch and relay that allows for proper installation. They should also have fairly easy instructions to follow.
The switch can be installed wherever, like inside your driverside glove box if you have one. And for the relay you'll probably need a voltmeter to mess around with the HL switch and find which wire turns 12v when parking lights are on.
Then if you have an auto, the wires can be routed between engine bay and cabin via the tear shaped hole, or through wiper cowl if you have an mtx.
For mounting, i guess you'd be best finding some stock brackets from a junkyard or just fabbing something up yourself.
