Figure 26 illustrates the steps described below:
1. Cut off all but 3/8" of foil shield from each of the twisted-wire
pairs.
2. Separate out the non-insulated, stranded drain wires and pull them
toward the cable center.
3. Rewrap the 3/8" foil shield around the twisted pairs.
4. Take the six pieces of 3/8" x 1" foil tape. One at a time, take each
and – beginning as close as possible to the pulled-out drain wires
and the cable’s outer jacket – wrap it tightly around a foil shield.
Make sure your wrapping flows in the same spiraling direction as
the shield you are wrapping it around. Wrap all six foil shields
identically.
5. Bring all the drain wires together and twist them together in the
center of the cable.

6. Break out one of the drain wires from the twisted group at 3/8" and
bend it toward the blue and black twisted pair, as shown in the
center of Figure 27.
7. At the 3/8" break-out point, quickly, but carefully, apply solder to
the clustered drain wires.
8. In the blue-and-black twisted pair, strip off 1/16" of the black
insulation, just above the foil tape and solder tinning. This will
leave 1/16" of exposed wire in the black lead.
