its a piece of cake to install fogs. Disconnect the battery! First, get a three prong switch, and then put it in a place in the cab. Find a hot you want to use (parking lights, headlights, etc), then splice the power into that wire. At the other end of your power wire, connect that to the power prong on your switch. Now youll want to run a wire from the fogs themselves to the switch. Lastly, ground the switch and the fogs, if necessary. Piece of cake man.
