When you tell us "wiring diagram", is for one specific circuit or you are refer to the firing order?

Have you removed the original connector from you original stereo? If you still have the original connector in place you can get a new connector from the Ford dealer that will plug into your existing wiring and into your new deck. Ford connections are unique to Ford and you need to adapt them for this application.

Take the car and deck to the dealer and tell them what you need. Everything just plugs in and your original amp and speakers in the car will work.

Having said that there was an adapter available at Wal Mart of all places that did work. You may want to check there.

If you have removed the original connector then you need a wiring diagram.

The amp is located under the rear passenger side window. You need to remove the plastic side wall to expose it if you need access there. You can trace the wiring if needed.

Under the front bottom edge of the rear seat are clips holding the seat in place. Open the clips and the seat lifts off. You can then get to the amp as needed.

you can go online to alldatadiy and request this diagram or maybe the local library may have the repair manual.
