Description
Number Item Description
p1Power conditionlThis shows the condition when the system receives battery positive voltage
(can be operated).
p2Fusible link
lThe double line shows that this is a fusible link.
lThe open circle shows current flow in, and the shaded circle shows current
flow out.
p3Fusible link/fuse locationlThis shows the location of the fusible link or fuse in the fusible link or fuse
box. For arrangement, refer to EL section (ªPOWER SUPPLY ROUTINGº).
p4Fuse
lThe single line shows that this is a fuse.
lThe open circle shows current flow in, and the shaded circle shows current
flow out.
p5Current ratinglThis shows the current rating of the fusible link or fuse.
p6Connectors
lThis shows that connectorE3is female and connectorM1is male.
lThe G/R wire is located in the 1A terminal of both connectors.
lTerminal number with an alphanumeric reference (1A, 5B, etc.) indicates that
the connector is an SMJ connector.
p7Optional splicelThe open circle shows that the splice is optional depending on vehicle appli-
cation.
p8SplicelThe shaded circle shows that the splice is always on the vehicle.
p9Page crossinglThis arrow shows that the circuit continues to an adjacent page.
lThe A will match with the A on the preceding or next page.
p10Common connectorlThe dotted lines between terminals show that these terminals are part of the
same connector.
p11Option abbreviationlThis shows that the circuit is optional depending on vehicle application.
p12RelaylThis shows an internal representation of the relay. For details, refer to EL sec-
tion (ªSTANDARDIZED RELAYº).
p13ConnectorslThis shows that the connector is connected to the body or a terminal with bolt

p25Connector number
lThis shows the connector number.
lThe letter shows which harness the connector is located in.
Example:M: main harness. For details and to locate the connector, refer to
EL section (ªMain Harnessº, ªHARNESS LAYOUTº). A coordinate grid is
included for complex harnesses to aid in locating connectors.
p26Ground (GND)lThe line spliced and grounded under wire color shows that ground line is
spliced at the grounded connector.
p27Ground (GND)lThis shows the ground connection.
p28Connector viewslThis area shows the connector faces of the components in the wiring diagram
on the page.
p29Common componentlConnectors enclosed in broken line show that these connectors belong to the
same component.
p30Connector colorlThis shows a code for the color of the connector. For code meaning, refer to
wire color codes, Number
p14of this chart.
p31Fusible link and fuse box
lThis shows the arrangement of fusible link(s) and fuse(s), used for connector
views of ªPOWER SUPPLY ROUTINGº in EL section.
The open square shows current flow in, and the shaded square shows cur-
rent flow out.
