FIGURE 11-25. Identification of wire bundles and har
nesses.
a. Wires for which identifications are
reassigned after installation, may be remarked
on sleeves at the termination of each wire
segment. It may be necessary to reidentify
such wires throughout their lengths to facili
tate ease of maintenance.
b. For high-density harnessed, shielded,
and jacketed multiconductor cables and when
using nonsignificant wire identification, color
coding or its alphanumeric equivalent may be
interchanged within the same harnesses. The
alphanumeric equivalent of the color code
should be as set forth in MIL-STD-681.
11-219. TERMINAL MARKING
SLEEVE AND TAGS. Typical cable mark
ers are flat, nonheat-shrinkable tags. Heat-
shrinkable marking sleeves are available for
marking wires and cables, and should be in
serted over the proper wire or cable and heat-
shrunk using the proper manufacturer recom
mended heating tool. (See figures 11-26
and 11-27.)

11-220. SLEEVES AND CABLE
MARKERS SELECTION. Sleeves and ca
ble markers must be selected by cable size and
operating conditions. (See tables 11-18
through 11-21).
a. Markers are printed using a typewriter
with a modified roller. Blank markers on a
bandolier are fed into the typewriter, where
they are marked in any desired combination of
characters. The typed markers, still on ban-
