You need a left and right hand pair of factory foglights with bulbs, the seperate plastic mounting panels that secure them into the bumper, and the stalk with the seperate twist switch for the fog lights. The foglight wiring with plugs will probably be inside the bumper already, Nissan seemed to include them whether or not the car had fogs from new. You also need to relocate a large fuse in the fuse box in the engine bay (the box is in front of the drivers side strut tower). If you have a FMIC, you might not be able to fit the fogs though, due to clearance issues with the piping and the back of the foglight housing.
