hey all! i am new to yourcobalt. i am trying to find some ideas on where i could put a custom switch for fog lights or led lights. any help w/ pics?

I have a 2005 ls and it didnt come with the grill inserts for fogs but has the hole and everything for fogs in the front bumper, so i found the inserts online but my question was do i have the wiring already setup for the fogs or would i have to do custom wiring? thanks.
