to hook it up as 2 port, you go:
compressor nipple --> restrictor --> Tee
branch 1 of Tee --> Wastegate nipple
branch 2 of Tee --> Port labeled "to compressor housing" --> port labeled "to wastegate" (this port is normally closed when de-energized and open when energized) --> inlet
Cap off the port that's currently to inlet (this port is normally open when de-energized and closed when energized).
