And if you are wanting to connect it to the actual intake where it will see vacuum....then it 100% must have a proper working PCV system in place so boost can never blow into the crankcase...and when on boost it must have a good clear method of venting.
Yes, yes, and yes. Just because it's harder doesn't mean it's not the proper thing to do

put the line pre-turbo. under normal cirmunstances, boost will never enter the crankcase and the suction from the turbo will give you vacuum.
