Symbols

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 “Z” arrow.

This broken line means
both terminals are in
connector C134.

A broken line means this part of the circuit
is not shown; refer to the circuit listed for
the complete schematic.

Where separate wires
join, only the splice is
shown; for details on 
the additional wiring, 
refer to the circuits
listed.

Wire choices for options or
different models are labeled
and shown with a “choice”
bracket like this.

A wavy line at the end of
a wire 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 means the branch of the
wire connects to another
circuit. The arrow points to the
name of the circuit branch
where the wire continues.

How To Use This Manual

This means the connector
connects to a lead (pigtail)
wired directly to the com-
ponent.

This means the connector
connects directly to the
component.

The name of the
component appears next
to its upper right corner
followed by notes about
its function.

This symbol represents
one bus bar inside the cap
of a junction connector. A
junction connector cap
contains several bus bars,
but only the one affecting
that circuit will be shown.
The dots represent tabs
on the bus that the wire
terminals connect to.

C103

The cavities (and wire terminals) in each
connector are numbered starting from the
upper left, looking at the male terminals from
the terminal side (or looking at the female
terminals from the wire side. Both views are in
the same direction so the numbers are the
same.) All actual cavities are numbered, even
if they have no wire terminals in them.

Female 
Terminal

The connector cavity number is listed next to
each terminal on the circuit schematic. The
cavity/terminal shown below is #6.

Remaining wires to
the same bus are
represented by a
broken line.

Splices are shown as a dot. Their location
and the number of wires may vary depend-
ing on the harness manufacturer.

A solid border line means the
entire component is shown.

A broken border line indicates
that only part of the component
is shown.

How To Use This Manual

Each wire ground (G) is
numbered for reference.

This symbol means the end of
the wire is attached (grounded)
to the car frame or to a metal
part connected to the frame.

These switches move
together; the broken straight
line between them means they
are mechanically connected.

A Zener diode blocks reverse
current at normal voltages just like
a rectifier diode. At high voltages,
however, a Zener diode allows
current to flow in reverse.

GRN/BLK

A rectifier diode works like a one
way valve. It allows current to
flow only in the direction of the
arrow.

Each “T” terminal (ring type)
is numbered for reference and 
location. A “T” terminal is
secured with a screw or bolt.

Shielding

Other types of switches are
controlled by a coil or a solid
state circuit. Unless otherwise
noted, all switches are shown
in their normal (rest) position,
with power off.

Solid-state

Ground – “G”

G101

G500

This symbol represents
the bus inside a ground
connector. The dots
represent tabs on the
bus that the wire
terminals connect to.
The ground symbol (large dot)
is the connection between the
bus and metal (grounded) part
of the car.

This ground symbol (dot
and 3 lines) overlapping the
component means the housing
of the component is grounded
to the car frame or to a metal
part connected to the frame.

This represents RFI
(Radio Frequency
Interference) shielding
around a wire. The
shielding is always
connected to ground.

This means power is supplied
when the ignition switch is in ON (II).
