You will see the valve and solenoid behind the blower pulley and to the left. You will need to disconnect the two vacuum lines connected into the blower manifold and put caps on the ports. You will also need to pull the vacuum line between the solenoid and control valve then install a cap on the solenoid where you pulled the vacuum line. Keep in mind this won't do you any good until you're making 12psi+ and it's also by-passing the safety barrier while your car is stock.
