The wiring diagrams contain thelatest 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 Figs 1 and 2. For additional information on ignitionsystems or distributor operation refer to Group 8D Ignition Systems.

WIRING DIAGRAM SHEETS AND INDEXES
The wiring diagram sheets are organized to show systems relating to the basic vehicle and all of its options. Add-on or non-factory options are not covered. Diagram pages are identified by a sheet number which is located at the lower right orleft 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 internal circuity, connectors, splices, and pin identification for controllers and modules. In certain instances a wire may be referenced to another sheet. When this happens, the wire will be

identified as to what it is ie: feed, ground etc, and where it is going (Fig. 3). This has been done to aid in the diagnosis of wiring and component problems. The index for the diagrams is located at the beginning. It covers all systems shown in the diagrams and is in alphabetical order. The main system and all related componentsare covered.

WIRE CODE IDENTIFICATION
Each wire shown in the diagrams contains a code (Fig. 4) 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. 5). If the wire has atracer and it is a standard color an asterisk 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.

The index identifies the main system and all components that relate to that system. There are also sections of the index that identify specific components only (for examplemodules, 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 battery and fuses. Then working into charging, starting, and ignition systems. After this they start at the front of the vehicle and work to rear of the vehicle. The diagrams end with connector identification pages.
