The port on the compressor is the pressure source. Most common if you have an internal wastegate in which case a line runs from that to your wastegate.

Eg.

You can source the pressure from elsewhere if you can’t tap the compressor, just DO NOT get it from the manifold, get it as close to the turbo as possible.
