6. CONNECTOR SKETCH
• Each connector sketch clearly identifies the
shape and color of a connector as well as terminal
locations. Non-colored connectors are indicated in
natural color.
• When more than two types of connector number
are indicated in a connector sketch, it means that
the same type connectors are used.
7. GROUND
Each grounding point can be located easily by re-
ferring to the corresponding wiring harness.
8. DIODE
A symbol is used to indicate a diode.
9. WIRE TRACING ON EXTENDED WIRING
DIAGRAMS
For a wiring diagram extending over at least two
pages, a symbol (consisting of the same characters
with arrows), facilitates wire tracing from one page
to the next.

11.POWER SUPPLY ROUTING
A symbol is used to indicate the power supply in
each wiring diagram.
"MB-5", "MB-6", etc., which are used as power-
supply symbols throughout the text, correspond
with those shown in POWER SUPPLY ROUTING
in the wiring diagram.
Accordingly, using the POWER SUPPLY ROUT-
ING and wiring diagrams permits service personnel
to understand the entire electrical arrangement of a
system.
12.CLASSIFICATION BY SPECIFICATION
When the wiring diagrams differ according to vehi-
cle specifications, the specification difference is de-
scribed by using abbreviations.
