Fog lights

I just purchased a new Mazda 5 Sport and am thinking of buying the fog lights. How hard of an install is this.
Thanks for any input

Mazda typically runs all fo the wiring that is necessary to hook up the foglights, even if the vehicle isn't equipped with them. On my Mazda3i (no fog lights) the wire harness and connectors are all in-place should I want to add the foglights. I believe the only "difficult" part is the installation of the switch, but I believe even that part is pretty straightforward.
