7.7 WIRING HARNESS CONNECTOR LABLES

Connector Labels

Connectors between harnesses are identified by the prefix "X"
and a sequentially assigned number. An optional suffix (letters
& numbers) may be added when multiple terminations occur
at one device or when there are optional connections.
Example:
X25 connects to X25 in another harness
X65A, X65B connect to different portions of one device.
X163 connects to X163A in ANSI and X163B in CE machine.

Component Labels

Every component on the vehicle has a unique identification. A
standard prefix letter is assigned according to the table below,
followed by a unique sequential number. An optional suffix
(letters & numbers) may be added when multiple terminations
occur at one device.
Terminals that are not loaded into connectors are considered
independent components and labeled in the same fashion.
