thiers already a hole in the fire wall.... i
(well thiers a spot for a hole)
it's just below the clutch, thiers a plastic plug that is kinda elevated from the rest of the metal, pull that out and drill through the sheet metal behind it, and the plug cn go back in , and you can feed the wires through the slot on the side.
I would recommend taking the front bumper cover off

that'll tell you how to take the front bumper off real easy and nice, ...
Once you have the bumper off, their are spots you can cut out that the factory fog lights go in. cut them out real neatly and mount the lights in thier.
You might as well clear out your headlights while you have the front bumper cover off.
you can buy more switches at Radio Shack, pepboys, walmart has a few.
