seems to me that a nipple>hose barb should screw in there to run a vacuum hose to your bov. and the other vacuum hose i believe tells the wastegate how much air the turbo is pulling mechanically. that is just a guesstimate so somebody will have to back me up on that.

that is not a port for the BOV

that, most likely, is there for some nissan boost sensor/controler, to read the boost pressure, or bleed pressure away from the actuator to allow for more boost

the BOV needs a vacuum line from the intake manifold, after the throttle body. if you hooked the BOV to the actuator for the wastegate, it would never let off.

the rod that has a vacuum line on it going to the actuator is the signal line. once enough boost is made, it forces the actuator to extend its arm, which is connected to the internal wastegate on that turbo you have pictured, allowing exhaust to bypass the turbine and limit the amount of boost the turbo will make.
