16 SwitchThis shows that continuity exists between terminals 1 and 2 when the switchis in the A
position. Continuity exists between terminals 1 and 3 when the switch is inthe B posi-
tion.
17 Assembly parts Connector terminal in component shows that it is a harness incorporated assembly.
18 Cell codeThis identifies each page of the wiring diagram by section, system and wiring diagram
page number.
19 Current flow arrowArrow indicates electric current flow, especially where the direction ofstandard flow (ver-
tically downward or horizontally from left to right) is difficult to follow.
A double arrow “
” shows that current can flow in either direction depending on cir-
cuit operation.

preceding pages.
22 Shielded line The line enclosed by broken line circle shows shield wire.
23Component box in
wave lineThis shows that another part of the component is also shown on another page (indicated
by wave line) within the system.
24 Component name This shows the name of a component.
25 Connector numberThis shows the connector number.
The letter shows which harness the connector is located in.
Example:M: main harness. For detail and to locate the connector, refer to EL-556, “Main
Harness”. A coordinate grid is included for complex harnesses to aid in locating connec-
tors.
26 Ground (GND)The line spliced and grounded under wire color shows that ground line is spliced at the
grounded connector.
27 Ground (GND)This shows the ground connection. For detailed ground distribution information, refer to
EL-24, “GROUND DISTRIBUTION”.
28 Connector viewsThis area shows the connector faces of the components in the wiring diagramon the
page.
29 Common componentConnectors enclosed in broken line show that these connectors belong to thesamecom-
ponent.
30 Connector colorThis shows a code for the color of the connector. For code meaning, refer to wire color
codes, Number 14 of this chart.
31Fusible link and fuse
boxThis shows the arrangement of fusible link(s) and fuse(s), used for connector views of
“POWER SUPPLY ROUTING” in EL section.
The open square shows current flow in, and the shaded square shows current flow out.
32 Reference areaThis shows that more information on the Super Multiple Junction (SMJ), Electrical Units,
exists at the end of the manual. Refer to GI-20 for details.

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-7, “HAR-
NESS CONNECTOR”.

Male and female terminals
Connector guides for male terminals are shown in black and
female terminals in white in wiring diagrams.

Connector numbers in a single circle M33 indicate harness
connectors.
COMPONENT INDICATIONNJGI0003S0203Connector numbers in a double circle F211 indicate compo-

SWITCH POSITIONSNJGI0003S0204Switches 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.

SGI862-A
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 “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.

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 “SUPER MULTIPLE
