GENERAL INFORMATION

INTRODUCTION

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.
Components shown with a dashed line instead of a solid line indicate not all circuits are shown in this
particular diagram (circuits shown in system diagrams are typically applicable to that system only). The
remaining circuits connected to that component will be shown in the appropriate system that they apply to.
Today, the wiring diagram necessary to support a given repair procedure is included within that article or a
link is provided to the appropriate SYSTEM WIRING DIAGRAM article. For example, the wiring diagram
for a Ford EEC-IV system may be included in ENGINE PERFORMANCE and WIRING DIAGRAMS
articles for Ford Motor Co. The wiring diagram for a cruise control system may be included in
ACCESSORIES & EQUIPMENT section for the specific vehicle manufacturer, and the wiring diagram for
an anti-lock brake system may be included in BRAKES and WIRING DIAGRAMS for the specific
manufacturer.
WIRING DIAGRAMS cont ains all wiring diagrams not in cluded in STARTING & CHARGING
SYSTEMS and ACCESSORIES & EQUIPMENT. Th is includes: Data Link Connectors, Ground
Distribution, Power Distribution, Engine Performance, Electri c Cooling Fans, Anti-Lock Brakes, Electronic
Suspension and Electronic Steering wiring diagrams. The Data Link Conne ctors wiring diagrams show the
circuits by which the various on-board computers exchange information, and the diagnostic connectors used
for diagnosis and their location. The Ground Distribution wi ring diagrams show all vehicle ground points,
their location, and the components co mmon to those ground points. The Po wer Distribution wiring diagrams
show the power feed circuits and the components common to those power feeds.
Wiring diagrams used to support the information in ACCESSORIES & EQUIPMEN T 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. Component locations are identified on the wiring diagrams. Any wires that do
not connect directly to a component are identifi ed on the diagram to indicate where they go.
