         Using Wiring Diagrams

         All Models

         INTRODUCTION

         Mitchell 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 Mitchell
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 Mitchell diagrams are normally
         self-explanatory. If necessary see ABBREVIATIONS
         article in GENERAL INFORMATION.

         IDENTIFYING WIRING DIAGRAM SYMBOLS

NOTE:    Standard wiring symbol are used in Mitchell 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.
