Each puck has a plug to go into a dimmer, and a switch, I got mine at Lowes. The dimmer then plugs into an outlet, luckily I have an outlet already in the cabinet above my stove, so all I have to do is mount the dimmer box in that cabinet and plug it in. The wiring for each puck is a 18 gauge wire, so i went to the store and picked up two 8ft, 18 guage ext. cords, that i will splice and use as extensions to the furtherest pucks.
