The current sensing relay senses a current in your furnace's 110 volt  fan power line by proximity. Simply run the fan wire through the top loop of the relay and when the fan turns on, the relay closes, allowing the 110 volt power on the relay side to flow through and turn on any device, such as a 110 volt humidifier, duct booster fan, etc.
