Mine is after the plate as well FWIW.
BOV won't do anything to prevent vacuum in plenum chamber after the throttle. BOV is installed before throttle.


I personally wouldn't install WG signal after the throttle as it may induce peculiar surging behavior at certain throttle openings on some engines. It will also subject membrane to both boost and vacuum which might and might not shorten it's life, as WG membranes are only ment to be subjected to boost. YMMV.
