Buying foglights....

So this girl I work with has a friend...(this is not one of those stories, sorry to disappoint) but she drives a 2005 Tib. Anyways, she's selling her car, and I asked her if I could buy her foglights, considering foglights add hardly any value to the car she was cool with it. So for 40 bucks I'm gonna be getting a set. My question is, what to I need to remove to make this setup as smooth as possible? Obviously the fogs and the switch, but should I clip both the foglights and the switch wiring harnesses so I have both the male and female connectors? Is there a way I could wire them up with all 3 sets of harnesses to where it is basically OEM, or should I just worry about running them through a fuse in the engine bay and hook them up to the FL Switch like that.
Let me know the best way to go about this...
