18 Cell code  This identifies each page of the wiring diagram by section, system and wiring diagram page
number.
19 Current flow arrow  Arrow indicates electric current flow, especially where the direction of standard flow (vertically
downward or horizontally from left to right) is difficult to follow.
 A double arrow “ ” shows that current can flow in either direction depending on circuit operation.
20 System branch  This shows that the system branches to another system identified by cell code (section and
system).
21 Page crossing  This arrow shows that the circuit continues to another page identified by cell code.
 The C will match with the C on another page within the system other than the next or preceding
pages.
22 Shielded line  The line enclosed by broken line circle shows shield wire.
23 Component box in
wave line  This 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 number  This 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 PG section "Main
Harness", “Harness Layout”. A coordinate grid is included for complex harnesses to aid in lo-
cating connectors.
26 Ground (GND)  The line spliced and grounded under wire color shows that ground line is spliced at the ground-
ed connector.
27 Ground (GND)  This shows the ground connection. For detailed ground distribution information, refer to
"Ground Distribution" in PG section.
28 Connector views  This area shows the connector faces of the components in the wiring diagram on the page.
29 Common component  Connectors enclosed in broken line show that these connectors belong to the same compo-
nent.
30 Connector color  This shows a code for the color of the connector. For code meaning, refer to wire color codes,
Number 14 of this chart.
31 Fusible link and fuse
box  This shows the arrangement of fusible link(s) and fuse(s), used for connector views of "POW-
ER SUPPLY ROUTING" in PG section.
The open square shows current flow in, and the shaded square shows current flow out.
