No pics but maybe I can tell you.
Either out of turbo or from a port on the intake, This will be your pressure line( not vacuum). I guess you know you will no longer be using your boost solenoid or factory Y. Run this line to the bottom port ( Holding wg in upright position ). Some where in this line, put a TEE, out of TEE, go through an air regulator, out of reg. to top port. What you are doing is---using compressed air (boost) to put more pressure on the diaghpram, which in turn holds the gate shut, which in turn raises boost.
