The WG actuator doesnt need vacuum, but I agree with Whitey the best place for Boost/Vac source for the wastegate is the intake manifold. Most turbos are designed to use the little nipple off the compressor housing, but where is the first place boost is going to build up? obviously right there. When going to the intake manifold it makes the turbo spool a bit faster since it takes longer for pressure to build up in the intake mani rather then compressor housing.
