The two under the manifold are boost/vac sources. The ones on your throttle body are boost only sources. You should have one that sticks out on the right side of the upper manifold for the FPR. It's hard to tell you what those lines should go to because everyone's setup is different. Wastegate needs boost only, charcoal canister needs vac, fuel pressure/boost/bov's need to see pressure differential, I.e. boost and vac. What external vac/boost systems are you running?
