One is the pressured hose, connects to the pressure side nipple of the radiator. Older RS radiators won't have that nipple. Tap and add one.

The other is a pressure relief, on most wrx's it goes directly to the lower plastic reservoir since there's no lower radiator cap. If you have a lower radiator cap, you can tee it to the reservoir line.
