throttle body dosent need any,

MBC line should come from a source as close to the turbo as possible, to the MBC, then to the wastegate.

FPR needs a line coming from the intake manifold.

BOV also needs a line from the intake manifold. preferably NOT from a T splitter connected to the fpr.

GM MAP SENSOR can be should be located either in the upper intercooler pipe or intake manifold if your just using it for a boost reference, not 100% sure where you need it for speed density.

also there should be a big line on the back of the intake manifold that goes to your brake booster.

EDIT: there is also a line that runs from the intake manifold to the valve cover, and another line that runs from the valve cover to the intake pipe.
