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. \\

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.
