Ours is a 2 port valve which really isn't a big deal, would just need to find something to keep water and dirt out without blocking it off (will still need to vent pressure from the actuator diaphragm). The second thing to do before hooking it up is get a ohms reading between the two wires and compare it to the stock one. If the ohms are to low it will not only react slower but could also damage the ECU and to high or low and the ECU will read it as defective and set a code (tried using the Greddy valve).
