Drinkypoo is right - the T444e and the PowerStroke share 99% of the same parts. What might be different are the cut-off dates for when which engine went into which vehicle. For instance, in the Ford trucks, the 99.5-03 share one version of the engine, whereas the 94-97 share another version. The T444 (no e) was in the pre 94's. So when you say 1997 to a Ford owner, it might mean something different to a school bus mechanic.
My suggestion would be to take a few pictures - fuel bowl and turbo should clear this up - and let us "cross reference" it to which group it correlates with in our lingo.
Here is the schematic you asked for assuming it is a T444e you are working on - http://www.thedieselstop.com/faq/949...veic_final.pdf
As you can see, it is an International schematic that is what we Ford guys order our parts from.
