Instructions
NOTE: In the Examples shown on these pages, an 'X' is used where a number would appear on an actual Figure.Harness Component Numbers
Connectors
Harness Code + Connector Number + Pin Number
Example: FC7-24 (pin number is separated by a dash)
NOTE: Door harness use common connector numbers with D, P or R added to indicate the door-Drive, passenger, Left rear, Right rear.
Splices
Harness Code + S + Identification Number
Example: CAS3 (no dash is used)
NOTE: In order to avoid unnecessary circuit complication, multiple splices (more than two wires) within components, in wires leading from input components to multiple circuits and in harness 'ground' sides are simplified so as not to show wires from other circuit.
Example
Splices:
Grounds
Harness Code + G + Identification Number
Example :BTG14 (no dash is used)
NOTE: Ground identifications that include 'L' or 'R' after the number indicate that the eyelet has two 'legs'. The 'L' or 'R' identifies the particular leg of the eyelet to which the wire is connected.
Diodes
Harness diodes occur at connectors and are depicted as components and identified by a connector number.
Example:
Diodes:
Relay Connectors
Relay connector numbers are shown within the relay. The harness code is shown in the upper portion of the relay; the pin (terminal) number is shown adjacent to the pin.
NOTE: Certain relays are paired and share a modular connector. In this instance, the relay terminal code is included in parentheses.

Relay Connectors:
Reference Symbols
Reference symbols are used for three purposes:
^ to allow the user to complete the individual system circuit to power supply or grounds
^ to refer the user to a related circuit
^ to identify control module inputs, outputs and signal grounds
Battery Power Supply:
Battery Power Supply
The symbol represents a direct battery power supply and refers the user to figure 01.1, 01.2, 01.3
Use the Hyperlink to access Figure Numbers referred to in the wiring diagram. Refer to -- Vehicle / Diagrams Electrical Diagrams
Ignition Switched Power Supply:
Ignition Switched Power Supply
This symbol represents ignition switched power supply and refers the user to figure 01.4. The suffix I indicates auxiliary power. Power is supplied in ignition switch key positions I (Auxiliary) and II (Ignition). The suffix II indicates ignition power. Power is supplied in ignition switch key position II (Ignition) and II (Ignition) and III (Engine Crank).
Ignition Switched Ground:
Ignition Switched Ground
This symbol represents an ignition switched ground and refers the user to figure 02.1.
No suffix indicates Crank. Ground is completed in Ignition switch key position III (Engine Crank). The suffix I indicates auxiliary ground. Ground is completed in ignition switch key position I (Auxiliary) and II (Ignition). The suffix II indicates ignition ground. Ground is completed in Ignition switch key position II (Ignition) and II (Engine Crank).

Logic Ground:
Logic Ground
This symbol represents a logic ground and refers the user to figure 02.2.
Figure Number Reference Flag:
Figure Number Reference Flag
This symbol refers the reader to a figure number only. It does not refer to a flag with the same number on a different figure. As used in figure 01.1 through 02.2, the reference flag refer the user to a continuation of the circuit. In this instance, the user matches the number to a power supply or ground symbol to trace the circuit.
BPM because the body processor module appears numerous times, the abbreviation BPM is used in the reference flag on figure

Control Module Input, Output, Data Line And Signal Ground:
Control Module Input, Output, Data Line and Signal Ground
These four symbols are employed to assist the user in visualizing the 'logic' of circuits containing control modules. The symbols identify control module input, output, data line and signal ground pins. These symbols are also employed on the corresponding data page.
