How do I connect thermostat wires to an AC unit?

To connect thermostat wires to an AC unit, first turn off the power to the unit. Then, match the wire colors from the thermostat to the corresponding terminals on the AC unit. Typically, the wires are connected to terminals labeled R, Y, G, and W. Use a screwdriver to secure the wires in place. Finally, turn the power back on and test the thermostat to ensure it is working properly.
