How To Use This Manual
The next few pages describe how this manual is organized. They also
exolain what kind of information the manual contains, what that
information means, and how to use it to troubleshoot electrical problems.
Circuit schemalics break the entire electrical system into individual
syslems, like the Low Fuel Indicator Light on the next page.
Only electrical components that work together are shown together,
so you won't be distracted by unrelated wires.
Explanations of the abbreviations and symbols used in the schematics
begin on page E. You'll need to know what they mean before you can use
a schematic effectively.

How To Use This Manual
Circuit Schematics
Each schematic reoresents one circuit.
A circuit's wires and components are
arranged to show current flow, from
power at the top of the page, to ground,
at the bottom.
Other circuits may share power or ground
terminals or wiring with the circuit shown.
A wire that connects one circuit to
another, lor example, is cut short and has
an arrowhead at the end of it pointing in
the direction of current flow. Next to the
arrowhead is the name ol the circuit or
component which shares that wiring. To
quickly check shared wiring, check the
operation of a component it serves. lf that
component works, you know the shared
wiring is OK.
All connectors are numbered (C709,
C416, etc.). Below each connector
number (except those for components)
is the number of a ohoto in the back
of the book showing the connector's
location on the car. Connector cavities
are also numbered. The numbering
sequence begins at the top left corner
of the connector as seen from eilher of
the viewpoints shown on page E.
Disregard any numbers molded into the
connector housing.
Wires are identif ied by the abbreviated
names of their colors; the second color is
the color of the stripe. Wires are also
identif ied by their location in a connector.
The number "2" next to the male and
female wire terminals at C416, for
example, means those terminals join in
cavity 2 of connector C41 6.
A complete description of schematic
symbols begins on page @.
O,e
Arowhead meanswire connects toanother ciacuit;it points in directionof current tlow.
"OK" note tellsYou how tocheck sharedwiring.
"HOT" label tells you whenthe ignition switch suppliesDower lo the fuse. \\

Power Distribution schematics show how power is supplied from the positive battery terminal to
various circuits in the car. Refer to the Power Distribution section to get a more detailed picture
of how power is supplied to the circuit you're working on.
From Battery to lgnition Switch, Fuses, and Relays
lndividual circuit schematics begin with a fuse. The first half of Power Distribution, however,
shows the wiring "upstream" between the battery and the f uses.

Power Distribution Schematics
From Fuses to Relays and Components
The second half of Power Distribution shows the wiring "From Fuses to Relays and
Components." This can speed your troubleshooting by showing which circuits share fuses. lf
Power Distribution shows that an inoperative circuit and another circuit share a fuse, check a
component in the other circuit. lf it works, you know the fuse is good and power is available to
the inooerative circuil.

Component Locations
To see where a component or connector is located on the car, look up its photo number in the
Component Location section in the back of the book. The photo will also tell you the color of
the connector. and how manv cavities it has.

lf there is no photo number below or beside a connector, ground, or terminal number, look up
that connector, ground, or terminal number in the appropriate Connector ldentification Chart.
The chart will tell you the color of a connector, how many cavities it has, where it's located,
and what component or harness it connects to. On the page opposite that chart you'll find an
illustration of the related harness.

Circuit ldentification for In'Line and Fuse Box Connectors
tuse the chart (on page 204, sample below) to help diagnose multiple symptoms in separate
circuits which could be caused by a single problem in a connect,oishared by those circuits'
Here's how that chart could help you find such a problem:
1. Pick one of the multiple symptoms and look up the schematic for that circuit'
2. Make a list of all in-lrne and fuse box connectors in that schematic (include page numbers).
3. Then, in the chart, look up each connector on your list to see if circuits related to the other
symptoms run through one of them. lf they do, inspect that connector for the problem.
Example: The horn, A,/C, and the right headlight don't work. List all in-line and fuse box
connectors in the horn circuit and then check the chart (sample below). You find that C211 is
common to the A,/C circuit and the headlight circuit, so you inspect c211 and find the problem:
bent terminals.

A wavy line at the end of
a wrre means the wire is
broken by the binding of
the book or by a "choice"
bracket but continues on
the next page.
Wire insulation can be
one color, or one color
with another color stripe.
(The second color is
the stripe.)
This circuit continues on
another page. (The arrow
shows direction of current
flow.) To follow the RED/
BLK wire in this example,
you would turn to page 23-5
and look for the "2" aftow.
This means the branch of the
wire connects to another
circuit. The arrow points to the
