The single speed wiper motor has two terminals marked "1" and "2" ... as I
recall the 2 speed motor has 3 wires coming out of the case rather than the
two terminals.

Try applying power between the #1 and #2 terminals.  I forget offhand which
is which (it's important), but it should run either way.  The terminal that
is wired to the park switch should be connected to the switch in the car,
the other one gets the solid green wire (fused power whenever the ignition
switch is on).
