Those cooper wire things you see are capillary tubes with bulb sensors at the end. Should be careful managing them, not to sharp bend them. Some of the capillary tubes are charged with gas, and the gas in them is what makes them work. You can buy it where it's cheaper in price. The $100 genuine valve will work as good as the Advance one, if they are exactly the same, properly installed, and insulated. I got mine at a local Auto A/C parts store... So if the one you bought it's not the same as the old you have, get it change. If they don't have the same one, ask for your money back and look for it in another place.
