For the purpose you describe the 3 pin connectors
are just serial connections.  To translate to a
typical DB25 connector you can just translate them
to:

3PIN --- 25PIN
==============
 3 ------- 3
 2 ------- 2
 1 ------- 7

Heck even if I'm wrong, how many combinations
to 2, 3, & 7 can there be?  In any case the
pins must go to those DB25 pin numbers, in
whatever order works.
