Note: Pin 1 arrow is bottom right!  Arrow should be visible
if cable is inserted correctly.

Strip a couple of inches of the CAT-5 outer sleeve.

Untwist the pairs and press them into the slots indicated.

Install the clamping bar to hold the wires in place.

Clip off both ends of the ground connection between pins 39(A)
and 36(E) adjacent to the connector body.  Clip loose ends
off each wire adjacent to the connector body, leaving intact
the jumper between 36(E) and 30(M).

Add a handle, if available, to the strain relief.  Fold the
wires around the top of the connector body and install the
the strain relief (with handle, if available) over them.

The male DB25 solder cup connector installs on the other end
as follows:

Note: This time pin 1 is on top, and note that physically
proximate pins are not numbered consecutively!

Be sure to install the connector hood, and ensure that the 
cable is clamped such that can not move inside the hood.
