         INTRODUCTION

         This cd obtains wiring diagrams and technical service

bulletins, containing wiring diagram changes from the domestic and

import manufacturers. These are checked for accuracy and are all

redrawn into a consistent format for easy use.

         In the past, when cars were simpler, diagrams were simpler.

All components were connected by wires and diagrams seldom exceeded 4

pages in length. Today, some  wiring diagrams require more than 16

pages. It would be impractical to expect a service technician to trace

a wire from page 1 across every page to page 16.

         Removing some of the wiring maze reduces eyestrain and time

wasted searching across several pages. Today the majority of these

diagrams follow a much improved format, which permits space for

internal switch details.

         Wiring diagrams are drawn in a "top-down" format. The

diagrams are drawn with the power source at the top of the diagram and

the ground point at the bottom of the diagram. Components locations

are identified on the wiring diagrams. Any wires that don’t connect

directly to a component are identified on the diagram to indicate

where they go.

         IDENTIFYING WIRING DIAGRAM ABBREVIATIONS

NOTE:    Abbreviations used on these diagrams are normally

         self-explanatory. If necessary see  ABBREVIATIONS

         article in GENERAL INFORMATION.

         IDENTIFYING WIRING DIAGRAM SYMBOLS

NOTE:    Standard wiring symbol are used in these diagrams. The

         illustration below will help clarify any symbols that are

         not easily understood at a glance. Most components are

         labeled "Motor", "Switch" or "Relay" in addition to being

         drawn with the standard symbol.

         WIRING DIAGRAM COMPONENT LOCATIONS

         When trying to locate a component in a wiring diagram and you

don’t know the specific system where it is located, use this handy

component locator to find the system wiring diagram in which the

component is located. Then, go to that system and locate the component

within the wiring diagram.

         For example, if you don’t know the specific system in which

the ignition switch is located, look up ignition switch in the wiring

diagram component location tables and go to the appropriate wiring

diagram(s) which contain either full or partial views of the ignition

switch. The full view of the ignition switch is located in Power

Distribution.

         The first listing for the component will be the full or most

complete view of the component. Additional listings will be partial

views of the component. Not all components are used on all models.

         All components will have a partial view in Ground

Distribution and Power Distribution. Data Link Connectors show

connecting circuits between modules. Alternate names for components

may be listed in wiring diagram component locations tables.
