How do I wire this Leviton switch?
You'll start by connect the grounding conductor to the green screw. The black wires that are currently attached to the old switch, will attach to the black and brass colored screws on the new switch. Finally you'll have to locate a grounded "neutral" wire; or group of wires, within the box. Using a twist-on wire connector, connect a short bit of wire to the grounded "neutral" wire(s). Connect the other end of the short bit of wire, to the silver screw on the new switch.
