you can call Ford and ask them to email you the vacuum line diagram. Otherwise, you would need to reach out to local Ford dealers to ask them to email you the diagram.
you have a single 3 or 4 pin connector to the coil pack. Someimes the wires get corroded and break off at the connector. Ford has a pigtail kit to fix that issue. Usually a misfire with the check engine light on.
Green/bluestripe is from ignition switch
Black/green stripe is to PCM (computer)
Black/orange stripe is to PCM
These last 2 wires are what the PCM uses to fire the spark plugs 2 at a time.
If it's equipped with the 2.0L SPI engine (eighth digit of the VIN is 'P'), the most common place for a vacuum leak on these engines, is from the PCV hose that runs from the valve cover to the back of the throttle body. Where it usually rots through is the elbow at the back where it connects to the throttle body. Hope this helps.

your engine code means "big leak" in the evap control system, this system has alot of pieces, but you are looking for a vacuum leak most probably, look at your vacuum hoses, and refer to the vacuum diagram stuck under your hood for routing, see if you have a bad hose, or disconnected hose some where. these are small vacuum hoses that attach to the purge valve, air filter housing, and charcoal cannister. let me know what you find.
