I would think that it would be mounted on the canister itself, but it may be under the hood attached to one of the vacuum lines going into the intake, it may be located on the fire wall and possibly be called out on the vacuum hose diagram if Ford put the sticker under the hood, sorry I couldn't be more specific, You may get more answers in the 2004-2008 forum, good luck!
