Solenoid has three ports, call them A, B, and C.
A: common port, air always flow through this one, powered or not.
B: normally open port (open to A at no current, blocked at high current)
C: normally closed port (open to A at high current, blocked at no current)
Attach a hose Tee to a line connected to the pipe between the compressor and IC, one line of the Tee goes to the bottom chamber of the wastegate (boost pressure opens the gate), the other line of the Tee goes to Port C. Connect Port A to the top chamber of the wastegate. Attach a small muffler to Port B.
You'll have to figure out which port is which on your solenoid, easy to do, blow through each port when disconnected, find port C (blocked), power solenoid and find the new blocked port "A", don't hold current for long though.
This is a high duty = high boost setup, as the solenoid, when powered, is holding the gate closed by sending pressure to the top can of the gate.
