The wiring diagrams contain the latest information
at the time of publication.
Throughout this group references may be made to
a particular vehicle by letter or number designation.
A chart showing the breakdown of these designations
is included in the Introduction Section at the front of
this service manual.
SECONDARY IGNITION WIRING
Secondary ignition wiring is shown in Figures 1
and 2. For additional information on ignition systems
or distributor operation refer to Group 8D Ignition
Systems.
WIRING DIAGRAM SHEETS AND INDEXES
The diagrams are organized to show the basic ve-
hicle and all of its options. Add-on or non-factory op-
tions are not covered. The diagram pages are
identified by a sheet number which is located at the
lower right or left hand corner of each sheet.Page
numbers at the top of each page do not apply to
diagram sheets.
Diagram sheets show all information relating to
the system. This includes feeds, grounds, switch in-
ternal circuity, connectors, splices, and pin identifica-
tion for controllers and modules. All components,switches, and relays are shown in the at rest position
with the key removed from the ignition and the doors
closed.
In certain instances a wire may be referenced to
another sheet. When this happens, the wire will be
identified as to where it is going.
The index used for the diagrams is located at the
beginning of the section. The main system and all re-
lated components are covered.

WIRE CODE IDENTIFICATION
Each wire shown in the diagrams contains a code
(Fig. 3) which identifies the main circuit, part of the
main circuit, gauge of wire, and color. The color is
shown as a two letter code which can be identified by
referring to the Wire Color Code Chart (Fig. 4). If the
wire has a tracer and it is a standard color an aster-
isk will follow the main wire color. If the tracer is
non-standard the main wire color will have a slash (/)
after it followed by the tracer color.
CIRCUIT IDENTIFICATION
All circuits in the diagrams use an alpha/numeric
code to identify the wire and its function. To identify
which circuit code applies to a system, refer to the
Circuit Identification Code Chart. This chart shows
the main circuits only and does not show the second-
ary codes that may apply to some models.
LOCATING A SYSTEM
To locate a system or component in the diagrams,
refer to the alphabetical index at the front of the di-
agrams. Determine the diagram sheet number. Sheet
numbers are located at the lower right or left handcorner of each sheet.Page numbers at the top of
the page do not apply to diagram sheets.
The index identifies the main system and all com-
ponents that relate to that system. There are also
sections of the index that identify specific compo-
nents only (for example modules, lamps, etc.). Refer
to a components name in the index if you are unclear
as to what a system may be called.
Diagram sheets are arranged starting with the bat-
tery and fuses. Then working into charging, starting,
and ignition systems. After this they start at the
front of the vehicle and work to rear. The diagrams
end with connector identification pages.
COMPONENT IDENTIFICATION
When looking for a components location in the vehicle
refer to the Component Identification section index.
This section shows the wire harness routing and the
components location in the vehicle. When using this sec-
tion refer to the wiring diagrams for the general loca-
tion of the component. Then use the component
identification index to locate the proper figure number.
SPLICE LOCATIONS
Splice locations are indicated in the diagrams by a
diamond with a splice circuit code within it (Fig. 5
example 1). If there is more than one splice per cir-
cuit a small box will be connected to it with the
splice number in it (Fig. 5 example 2).
To locate a splice in the wiring harness determine
the splice number from the wiring diagrams then re-
fer to the splice location index. This section shows
the general location of the splice in the harness.

The wiring and components shown in this section
are divided into sections by vehicle line. When locat-
ing a specific wire routing or component, first turn to
the appropriate index, then look up thefigure num-
berthat refers to the component.Page numbers at
