Mount the solenoid valve in a position away from significant heat sources (such as the exhaust manifold and 
turbine), and where it is protected from rain or splashed water. The unused outlet of the solenoid valve should be 
positioned facing downwards to avoid ingress of dust, dirt and water.
DO NOT plug the un-used solenoid port, as this will prevent the controller from being able to adjust boost pressure.
