The wires you have are red, white, yellow and green? If so you would hook the wires up to the corresponding wires on the new thermostate. If the wires are not color coded this way you may have to clp the wires on the old thermostat so you have a reference to look at when hooking up the new thermostat. These are common color combinations for heating and cooling equipment: RED is your power wire, GREEN is the fan on or auto wire, the WHITE is the heat wire, and the YELLOW or BLUE is usually cooling.
