There are the 2 vacuum sources off the top of the intake manifold.

One is to be used only for the BOV.

The other one is the vacuum supply for the fuel pressure regulator.

T you boost gauge into the FPR vac line.

This has been covered a number of times already.

and your wastegate line should be there as well. fpr line works well.
