CONNECTOR SYMBOLS=NLGI0003S0201Most 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,“HAR-
NESS CONNECTOR”.
SGI363
+Male and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

HARNESS INDICATIONNLGI0003S0202+Letter designations next to test meter probe indicate harness
(connector) wire color.
+Connector numbers in a single circle M33 indicate harness
connectors.
COMPONENT INDICATIONNLGI0003S0203+Connector numbers in a double circle F211 indicate compo-
nent connectors.
SGI860
SWITCH POSITIONSNLGI0003S0204Switches are shown in wiring diagrams as if the vehicle is in the
“normal”condition.
A vehicle is in the“normal”condition when:
+ignition switch is“OFF”,
+doors, hood and trunk lid/back door are closed,
+pedals are not depressed, and
+parking brake is released.

DETECTABLE LINES AND NON-DETECTABLE LINESNLGI0003S0205In some wiring diagrams, two kinds of lines, representing wires,
with different weight are used.
+A line with regular weight (wider line) represents a“detectable
line for DTC (Diagnostic Trouble Code)”.A“detectable line for
DTC”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“non-detect-
able line for DTC”.A“non-detectable line for DTC”is a circuit
in which ECM cannot detect its malfunctions with the on board
diagnostic system.

MULTIPLE SWITCH=NLGI0003S0206The continuity of multiple switch is described in two ways as shown
below.
+The switch chart is used in schematic diagrams.
