Fog Light Installation Question

[Christato71]

Hello,
I was thinking about installing fog lights on my alero. I have a few questions before I buy anything: Since there is no existing switch for the fog lights I would need to buy something like this: http://tiny.cc/jyj6b. My question on this is, would there be a wire harness or some kind of connector behind the driver side vent for the fog light switch? And would there be some kind of connector on the out side of the car where the fog lights would mount? Or do I need to buy all of these connectors or harnesses separate?

Thanks!
