How can I determine for certain that the van is OBD-II? Is there a
distinctive diagnostic-connector shape (link to a picture), or perhaps
the number of pins can be counted to determine OBD-II vs OBD-I? It was
indeed manufactured in 1995, so this is something I need to figure out.

ODBII has a large D shaped 16 pin connector which is usually under the dash
in alignment with the steering column.

You can find pictures of the OBD II connector on the web, or look in any 97
or newer car. It has the general shape of an old printer connector. The OBD
I is shaped like a fat "L." Some of the low cost readers show the error code
three times, and if you don't disconnect it, reset the ECM.
I have reset the ECM on GM cars and ran them right through emissions with no
problems.

Thanks, Al. Based on the answers from yourself and others, I concluded
that the $100 units do not offer any functionality over the cheaper
ones, so I bought one on sale at "Harbor Freight" for $31.99.

First, is the diagnostic connector under the hood or under the
dashboard.

Last, check the VECI label, if it's OBD2, it will say.
