    One of the four wires is likely the low-voltage power supply and the other three go to the indoor fan relay, outdoor unit relay, and primary heat control. I would start with the red wire and connect it to black, observing if any part of the system comes on. Proceed with each possible pairing of wires until you have determined which one is the low-voltage power supply (connect to "R" terminal) and which of the remaining wires go to the indoor blower control ("G" terminal), outdoor unit ("Y" terminal), and primary heating control ("W" terminal). Any pairing that does not produce some function of the system excludes the low-voltage "hot".
