PGT Driver

Okay i have an AVCR and tial 38mm wastegate. It says to attach the com port of the acuator valve to the top of the wastegate which i thought was a vent, but now am not sure, then attach the side port to the a vaccum t of the pipe going to the throttle body. Now i thought the side port was for the singal. Could someone give an idea on what to do if the instructions are correct of i need to do something differnt.
