The nipple on top of the =>wastegate<= is a vent intended to be open to
atmosphere so the wastegate diaphragm can move freely and do its job:

The actual turbocharger itself should not have anything that looks like it
needs connecting to a vacuum line. There should be one oil line in, one oil
line out, one water line in, one water line out - all connected.
