On the norm it would be red to r, white to w green to g, and yellow to y,, but, in your case you need to go to the furnace and find out what the colors are comeing from, since I don`t know what kind of furnace you have I can`t say wheather to look at the circuit board so just match the wires from the furnace and ac as needed
