Circuit Schematics
o a
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.
