FORD CUSTOMER SERVICE DIVISION
Quality is Job 1
Ford Customer Service Division has developed a new WIRING DIAGRAM format for the 2000
RANGER. Our goal is to provide accurate and timely electrical service information.

2000 WIRING DIAGRAM FEATURES ORDERING INFORMATION

Schematic pages contain Component Location references to full-view illustrations and Information about how to order additional
Component Descriptions that describe the system function of a component. copies of this publication or other Ford publica-

“COMPONENT TESTING” procedures (CELL 149) tell the user how to perform diagnostic tions may be obtained by writing to Helm Incor-
tests on various circuits. porated at the address shown below or by call-

Connector End Views are located at the end of individual cells and are shown for connectors ing 1-800-782-4356. Other publications avail-
with five or more cavities; for connectors with ten or more cavities, a circuit function chart is able include:
provided.
Workshop Manuals

NOTES, CAUTIONS and WARNINGS contain important safety information.
Service Specification Books

Full view “COMPONENT LOCATION VIEWS” (CELL 151) help locate on-vehicle components.
Powertrain Control/Emissions Diagnosis

Circuit voltages are included on schematic pages to help simplify troubleshooting. Manuals

Cellular Pagination: A specific section (or cell) in all Wiring Diagrams is numbered by cell and
starts with page 1. For example: “HOW TO USE THIS MANUAL” is CELL 2 and begins with Helm Incorporated
page 2-1. P.O. Box 07150
Detroit, Michigan 48207

“IN-LINE CONNECTOR FACES” (CELL 150) are included for in-line connectors with six or
more terminals, to aid in servicing electrical wiring.

“C” numbers are assigned for all electrical connectors. “C” numbers are listed in the
“LOCATION INDEX” (CELL 152).

“HARNESS CAUSAL PART NUMBERS” (CELL 153) are included to aid in identifying
warranty concerns.

“HARNESS CAUSAL PART NUMBERS” contain a suffix to denote connector “gender” type
(F-socket, M-prior blade).

IMPORTANT SAFETY NOTICE

Appropriate service methods and proper
repair procedures are essential for the
safe, reliable operation of all motor ve-
hicles, as well as the personal safety of the
individual doing the work. This Manual pro-
vides general directions for accomplishing
service and repair work with tested, effec-
tive techniques. Following them will help
assure reliability.

There are numerous variations in proce-

dures, techniques, tools, and parts for
servicing vehicles, as well as in the skill of
the individual doing the work. This Manual
cannot possibly anticipate all such varia-
tions and provide advice or cautions as to
each. Accordingly, anyone who departs
from the instructions provided in this Manu-
al must first establish that the choice of
methods, tools, or parts does not compro-
mise personal safety or the vehicle
integrity.

HOW TO IDENTIFY A BASIC HARNESS NUMBER BY USING A “C” NUMBER

Understand these symbols before you use the following listing:

THIS MEANS A HARNESS CONNECTION THE DASHED LINE MEANS THAT ALL OF THESE THIS MEANS A COMPONENT CONNECTION
TERMINALS ARE IN THE SAME CONNECTION
C100M C100F
COMPONENT

C100F
C100M
THIS IS THE CONNECTOR HALF WITH C100
THE MALE TERMINALS C100M

THIS IS THE CONNECTOR HALF WITH THE UPPER FEMALE TERMINALS ARE IN C100F; THE F AND M ARE NOT USED WITH THE “C” NUMBER
THE FEMALE TERMINALS C100F THE LOWER MALE TERMINALS ARE IN C100M

Identify the basic harness part number by:

1. If the problem is in a connector, find the connector “C” number in the Wiring Diagram schematics. Then locate the “C” number in the following listing and
read the basic harness part number.
2. If the problem is not in a connector (such as a short or broken wire), then choose a connector located on the same harness that has the problem. Iden-
tify the “C” number of that connector. Locate the “C” number in the following listing and read the basic part number of the harness that has the problem.
