NOTE:
. Before installing the steering wheel, the front
wheels should be aligned straight ahead.. Be sure to install the harness wires so that theyare not pinched or interfering with other parts.. After reassembly. confirm that the wheels arestill turned straight ahead and that the steeringwheel spoke angle is correct (road test). lf minor
spoke angle adjustment is necessary, do so onlyby adjusting the tie-rods, not by removing andrepositioning the steering wheel.
Set the cancel sleeve so that the projections arealigned venically.

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

How To Use This Manual
Circuit Schematics
oa
Each schematic represents one circult. 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.
Shared Circuits
Other circuits may share power or ground
terminals or wiring with the circuit shown. A
wire that connects one circuit to another, for
example, is cut short and has an arrowhead
at the end of it pointing in the direction of
current flow. Nelit to the anowhead is the
name o{ the circuil or comoonent 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.
Connectors
All in-line and fuse box connectors are
numbered (C725, C416, etc.).
Component connectors are not numbered
but are identiJied by the name of the
component. lf a componenl has more than
one connector, each connector is assigned
a letter (A, B, C, etc.). Below most connector
numbers and comDonent names are
PHOTO and VIEW numbers. The PHOTO
number refers to a Dhoto in the back of the
book that shows lhe conneclor's location on
the car. The VIEW number refers to an
illustration in the back of the book that
shows the connector face, wire colors,
connector cavity numbers, and other details.
The connector cavity numbering sequence
begins at the top left corner oJ the connector
as seen from either of the viewooints shown
on page ffl . Disregard any numbers
molded into the connector housino.
Wires
Wires are identilied by the abbreviated
names of their colors; the second color rs the
color of the stripe. Wires are also identified 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 C416.
Symbols
