POWER SUPPLY ROUTING
This diagram is helpful in identifying specific prob-
lems
in the power supply portion of the electrical
circuits. For example, let's say
a vehicle has an in-
operative
rear window defogger A quick check
proves that meter and
gauges in the vehicle are
operative The power supply diagram shows that
there cannot be
a problem between the battery,
ignition relay, ignition switch or fuse since the
power supply circuit for the
rear window defogger
Example
BRANCH M/T model
AlT model
n
@ M/Tmodel
@ AITmodel

ABBREVIATIONS
is common with the meter and gauges. Therefore,
the cause of this specific problem must
lie past the
fuse, such
as in the wiring, rear window defogger,
or ground.
WIRING DIAGRAM
This diagram identifies types and number of con-
nectors, electrical
terminal positions in the connec-
tor, color coding of wires, and connector codes
Refer to the following example
CONNECTOR This shows that there connectors are white 6 terminal pin-type connectors
