IMPORTANT:

Twisted-pair wires provide an effective shield that helps
protect sensitive electronic components from electrical
interference. If the wires were covered with shielding,
install new shielding.
In order to prevent electrical interference from degrading
the performance of the connected components, you must
maintain the proper specification when making any
repairs to the twisted-pair wires shown :

The wires must be twisted a minimum of 9 turns
per 31 cm (12 in) as measured anywhere along the
length of the wires.

The outside diameter of the twisted wires must not
exceed 6.0 mm (0.25 in).
