WIRING SYSTEM
BASIC DIAGNOSTICS PROCEDURE
• When one set of connectors is viewed from the
front side, the pole numbers of one connector are
symmetrical to those of other. When these two con-
nectors are connected as a unit, the poles which
have the same number are joined.
• Electrical wiring harness:
The connectors are numbered along with the num-
ber of poles, external colors, and mating connec-
tions in accompanying list.
• The sketch of each connector in the wiring dia-
gram usually shows (A) side of the connector. The
relationship between wire color, terminal number
and connector is described in figure.
NOTE:
A wire which runs in one direction from a connector
terminal sometimes may have a different color from
that which runs in the other direction from that ter-
minal.
• In wiring diagram, connectors which have no ter-
minal number refer to one-pole types. Sketches of
these connectors are omitted intentionally.
• The following color codes are used to indicate
the colors of the wires used.
