Depends on what type you get. I happen to like the set I got at home depot (no guarantee they'll be there any more, but...) where there are two tiny screws that hold the wire into the plugs. As long as they're not solder ones, they're fairly easy. Of course, if they are solder ones, and you know how to solder, they're fairly easy.
