I've seen quite a few, and no two alike!  You'll probably just have
to play for a little while. Typically the pins are aranged in groups of
four
in a "T" shape to give you 3 ways of connecting 2 of them with 1 jumper.
Every other "T" is upside down to conserve space:

1 - pin for seg 1
2 - pin for seg 2
3 - pin for seg 3

1112333
 12223 

There is one "T" jumper per led segment -- eight per digit.
Each segment is:

on during turbo, or
on without turbo, or
always on, or
always off.

The always off is usually no jumper on that "T".
