When I turn the key on this unit makes a clicking sound.

That is the wastegate solenoid. It controls the amount of air pressure that is applied to the wastegate actuator. This in turn controls how much the wastegate opens when under higher boost. The green tube is the bypass that leads back to the intake, and the red line is the tube that connects to the wastegate actuator.
