Typically if there are two wires running from the furnace to the AC system then it means that the furnace has power already connected to it and it sends that through one of the wires up to the AC until the system calls for heat, at which point the relay will close and send power back to the furnace through the other wire. You'll want to connect the brown and white wire from the controller # ACRG15 to the other wire send power back to the furnace.
To determine which wire is which you can use a multimeter # PT89ZR and place one lead to a good ground and the positive lead to either wire. One wire should read 12v DC and would be the power running from the furnace to the AC. You'll connect the AC wire to the other furnace wire so it can send power to furnace to activate it as needed.
