HOW TO USE THIS GROUP
The purpose of this group is to show the electrical
circuits in a clear, simple fashion and to make trou­
bleshooting easier. Components that work together
are shown together. A l l electrical components used in
a specific system are shown on one diagram. The Teed
for a system is shown at the top of the page. A l l
wires, connectors, splices, and components are shown
In the flow of current to the bottom of the page. Wir­
ing which is not part of the circuit represented is ref­
erenced to another page/section, where the complete
circuit is shown. In addition, all switches, compo­
nents, and modules are shown in'the at rest posi­
t i o n w i t h the doors closed and the key removed
from the i g n i t i o n .
I f a component is part of several different circuits,
it is shown i n the diagram for each. For example, the
headlamp switch is the main part of the exterior
lighting, but it also affects the Interior lighting and
the chime warning system. I t is i m p o r t a n t to real­
ize that no attempt is made on the diagrams to
represent components and w i r i n g as they
appear on the vehicle. For example, a short
piece of w i r e is treated the same as a long one.
I n addition, switches and other components are
shown as simply as possible, w i t h r e g a r d to
function only.

intention is to organize information by system, con­
sistently from year to year.
CONNECTOFt/GiOUNi LOCATiOlS
Section 8W-90 contains connector/ground location
illustrations. The illustrations contain the connector/
ground number and component identification. Con­
nector/ground location charts i n Section 8W-90
reference the illustration number for components and
connectors.
Section 8W-80 shows each connector and the cir­
cuits involved with that connector. The connectors
are identified using the number on the Diagram
pages.
SPLICE LOCATiOlS
Splice Location charts in Section 8W-70 show the
entire splice, and provide references to other sections
the splice serves.
Section 8W-95 contains illustrations that show the
general location of the splices In each harness. The
illustrations show the splice by number, and provide
a written location.
10TES, CAUTIONS, and WARNINGS
Throughout this group additional important infor­
mation is presented In three ways; Notes, Cautions,
and Warnings.
NOTES are used to help describe how switches or
components operate to complete a particular circuit.
They are also used to indicate different conditions
