That looks like an old sequential. I didnt realise they has 2 vac ports on them?

Just like an external wastegate, one port goes to intake manifold and the other direct to pressure source from turbo.

by any chance you dont know which is which ????

I would assume the port on top (back) of it would go to manifold, while the one on the side to turbo...
