2-1 HOW TO USE THIS MANUAL
The purpose of this manual is to show electrical cir-
cuits in a clear and simple fashion to make trouble-
shooting easier.
NOTES, CAUTIONS and WARN-
INGS contain important information.
D
NOTES describe how switches and other compo-
nents operate to help complete a particular pro-
cedure.
D
CAUTIONS provide information that could pre-
vent making an error that may damage the
vehicle.
D
WARNINGS provide information to prevent per-
sonal injury.
The WARNINGS list on page 2-2 contains general
warnings to follow when servicing a vehicle.
Components that work together are shown
together. All electrical components used in a specific
system are shown on one diagram. The circuit
breaker or fuse is shown at the top of the page. All
wires, connectors, components and splices are
shown in the flow of current to ground at the bottom
of the page. If a component is used in several differ-
ent systems, it is shown in several places. For exam-
ple, the Headlamp Switch is electrically a part of
many systems and is repeated on many pages.
In some cases, a component may seem (by its
name) to belong to a system where it has no electri-
cal connection. For example, Radio Illumination is
electrically part of Instrument Illumination, but
because it has no electrical connection to the Radio
system, it is not shown on the Radio diagram.
Schematic pages contain references to full-view
illustrations and description notes for various com-
ponents. The references are reverse-text blocks
located next to each component and connector and
refer the user to the appropriate illustration page and
zone. The description notes describe the operation
of the component.
Schematic pages contain circuit voltages to help
simplify troubleshooting hints. 12V is used to imply
battery voltage on a component connector terminal,
and 0V is used to show that there should be continu-
ity to ground on that particular terminal. Conditional
voltages such as
“ 12V with the ignition switch in
RUN ” will also be provided. Troubleshooting hints
that can ’ t be simplified with circuit voltages will be
shown at the end of each cell.
Component connector face information specific to
a certain cell is found at the end of that cell. A Con-
nector Face Reference List is provided to locate con-
nector faces that are shown in different cells. Com-
ponent connectors with five or more terminals are
illustrated and are accompanied by a pinout chart
that lists the function of all circuitry associated with
that component.
“ GROUNDS ” (Cell 10) contains ground circuitry
shown in complete detail. This information is useful
for checking interconnections of the ground circuits
of different systems.
“ POWER DISTRIBUTION ” (Cell 13) contains
power distribution circuitry shown in complete detail.
This section displays how the various fuses are pow-
ered and, in turn, how each system is powered.
“ COMPONENT TESTING ” (Cell 149) contains
testing procedures for various switches. This
information includes schematics, component termi-
nal locations and step-by-step procedures.
“ IN-LINE CONNECTOR FACES ” (Cell 150) con-
tains illustrations of all the in-line connectors that
have 6 or more terminals. The terminals have pin
numbers assigned to them.
“ COMPONENT LOCATION VIEWS ” (Cell 151)
contains full-view illustrations which show the loca-
tion of components and connectors in the vehicle.
The “ LOCATION INDEX ” (Cell 152) provides the
base part numbers, locations, connector face refer-
ences and illustration references for all components,
connectors, splices and grounds.
HELPFUL REMINDERS
Before using the Wiring Diagrams for troubleshoot-
ing, refer to these HELPFUL REMINDERS:
1. The abbreviation T/O, for take out, used in the
Location Index (Cell 152), refers to the point at
which a group of wires branch off the harness
trunk. Refer to the wiring harness illustration.

2. If a connector serves the same purpose in two
separate versions (e.g., Automatic/Manual), but
is physically different,
two connector numbers
are used. However, if a connector serves the
same purpose in two separate versions (e.g.,
Automatic/Manual) and is physically the same,
but the wire colors are different, only
one connec-
tor number is used. If the same physical connec-
tor is used more than once, then more than
one
connector number is used.
