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.

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.

Troubleshooting Tests
Testing for Voltage Drop
Wires, connectors, and switches are designed
to conduct current wilh a minimum loss of
voltage. A voltage drop of more than one volt
indicates a Droblem.
'1. Place the digital volVohmmeter (DVOM) in
the appropriate DC volts range. Connect
the positive lead to the end of the wire
(or to the connector or switch) closest to
the bafterv.
Connect the negative lead to the other
end of the wire (or the other side of the
connector or switch).
Turn on the components in the circuit.
The DVOM will show the difference
in voltage between the two points. A
difference, or drop, of more than one
volt indicates a oroblem. Check the
circuit for loose, dirty, or bent terminals.
co
Testing lor a Short with a Test Light or DVOM
1. Remove the blown fuse and disconnect
the load.
2. Connect a test light or digital
oltr'ohmmeter
(DVOM), switched to the appropnare DC
volts range, across the tuse lerminals to
make sure voltage is present. You might
have to turn the ignition switch to ON:
check the schematic to see.
<-s80RT TOGFOUNO
Disconnecl lheload here.
Beginning near the luse box, wiggle the
harness. Continue this at convenient ooints
about six inches apart while watching the
test light or DVOM.
Where the test light goes off, or the DVOM
voltage drops to zero, there is a short to
ground in the wiring near that point.
NOTE: Always use a DVOM on high
impedance circuits. A test light may not
glow (even with battery voltage present).
