I'm looking at that cutaway, and I never caught that. Since according to Page 31, it's a "smaller control station" it has to be in the open areas as illustrated on Page 43. So, I would say it's probably near the center of the Engineering stack, as those decks are designed for Greevals, who are only 1 meter tall, (3'4"), So I'd put it where you can't see it in that illustration, near the center column.
