Power Distribution Schematics
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
Individual circuit schematics begin with a fuse. The first half of Power Distribution, however,
shows the wiring "upstream" between the battery and the fuses.

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 many cavities it has.

lf there is no photo number below or beside a component name or a connector, ground, or
terminal number, look up that name or number in the Connector-to-Harness Index that begins
on page 203. The chart lists how many cavities a connector has, where it's located, and what
it connects to. The related illustration shows the connector's location on the harness, and the
harness routing.

Connector Views
To see the configuration of a connector's cavities, look up its view number in the Connector
View section in the back of the book. Each view includes the color of the connector, where it
is located, and what it connects to.
Use the Connector Views to help locate the proper cavity when you need to probe a
connector. lt can be especially helpful if the connector has more than one wire of the same
cotor.
Connector views can also be used to help diagnose multiple symptoms in separate circuits
which could be caused by a single problem in a connector shared by those circuits. Here's
how:
1. Pick one of the multiple symptoms and look up the schematic for that circuit.
2. Make a list of all the in-line and fuse box connectors in that schematic (include page
numbers).
3. Then, in the Connector View section, look up each connector on your list to see il circuits
related to the other symptoms run through one of them. lf they do, inspect that connector
for the oroblem.
Example: The blower, rear window defogger, and the windshield wiper don't work. List all
in-line and fuse box connectors in the blower controls circuit and then check the Connector
View section (sample below). You find that C324 is common to the rear window defogger
circuit and wiper/washer circuit, so you inspect C324 and find the problem, bent terminals.

A wavy line at the end of
a wire means lhe wire is

This circuit continues on
another page. (The arrow

BLK wire in this example,
you would turn to page 23-5
and look for the "2" anow.
This means the branch of the
wire connects to another
circuit. The arrow Doints to the
name of the circuit branch
where the wire continues.

Connectors - "C"
The cavities (and wire terminals) in each
connector are numbered starting from the
upper left, looking at the male terminals trom
the terminal side (or looking at the female
lerminals f rom 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.

Switches
These switches move

noted. all switches are shown
in their normal (rest) position,
with power off.
This ground symbol (dot

Diodes
A rectifier diode works like a one

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