CONNECTOR SYMBOLS=NJGI0003S0201Most of connector symbols in wiring diagrams are shown from the
terminal side.
+Connector symbols shown from the terminal side are enclosed
by a single line and followed by the direction mark.
+Connector symbols shown from the harness side are enclosed
by a double line and followed by the direction mark.
+Certain systems and components, especially those related to
OBD, may use a new style slide-locking type harness connec-
tor. For description and how to disconnect, refer to EL-5, ªHAR-
NESS CONNECTORº.
SGI363
+Male and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

HARNESS INDICATIONNJGI0003S0202+Letter designations next to test meter probe indicate harness
(connector) wire color.
+Connector numbers in a single circle M33 indicate harness
connectors.
COMPONENT INDICATIONNJGI0003S0203+Connector numbers in a double circle F211 indicate compo-
nent connectors.
SGI860
SWITCH POSITIONSNJGI0003S0204Switches are shown in wiring diagrams as if the vehicle is in the
ªnormalº condition.
A vehicle is in the ªnormalº condition when:
+ignition switch is ªOFFº,
+doors, hood and trunk lid/back door are closed,
+pedals are not depressed, and
+parking brake is released.
DETECTABLE LINES AND NON-DETECTABLE LINESNJGI0003S0205In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
+A line with regular weight (wider line) represents a ªdetectable
line for DTC (Diagnostic Trouble Code)º. A ªdetectable line for
DTCº is a circuit in which ECM can detect its malfunctions with
the on board diagnostic system.
+A line with less weight (thinner line) represents a ªnon-detect-
able line for DTCº. A ªnon-detectable line for DTCº is a circuit
in which ECM cannot detect its malfunctions with the on board
diagnostic system.

REFERENCE AREA=NJGI0003S0207The Reference Area of the wiring diagram contains references to
additional electrical reference pages at the end of the manual. If
connector numbers and titles are shown in the Reference Area of
the wiring diagram, these connector symbols are not shown in the
Connector Area.

Super multiple junction (SMJ)
In a wiring diagram, the SMJ connectors include a letter of the
alphabet in the terminal number.
SMJ connector numbers are shown in the Reference Area of the
wiring diagram. SMJ terminal arrangement can be found on the
electrical reference pages at the end of the manual. For terminal
arrangement of these connectors, refer to the ªSUPER MULTIPLE
JUNCTION (SMJ)º electrical reference page at the end of the

manual.
Fuse block Ð Junction box (J/B)
Fuse block Ð Junction box (J/B) connector number is shown in the
Reference Area of the wiring diagram. For connector terminal and
fuse arrangement, refer to the ªFUSE BLOCK Ð Junction Box
(J/B)º electrical reference page at the end of the manual.
Fuse and fusible link box
For fuse arrangement in the fuse and fusible link box, refer to the
ªFUSE AND FUSIBLE LINK BOXº electrical reference page at the
end of the manual.
Electrical units
Electrical unit connector symbols are shown in the Connector Area
of the wiring diagram.
However, when there is not enough space to show the connector
terminal arrangement in the Connector Area of the wiring diagram,
the electrical unit connector number is shown in the Reference
Area of the wiring diagram. For electrical unit connector terminal
arrangement, refer to the ªELECTRICAL UNITSº electrical refer-
ence page at the end of the manual. Most of the electrical unit
connectors on this page are shown from the harness side of the

nector terminal arrangement, refer to the ªJOINT CONNECTOR
(J/C)º electrical reference page at the end of the manual.
