If it's anything like other Fords, there's still a "conventional" drive gear on
the output shaft and a hole in the tailshaft housing, but instead of having a
cable screwed into the hole, an electronic module is installed.

In fact, here's the part listing for your car...

All you need to do is find the appropriate gear to put on the shaft.
Call Ford, or a local tranny shop.
