SWITCH POSITIONS
Switches are shown in wiring diagrams as if the vehicle is in the “normal” condition.
A vehicle is in the “normal” condition when:
Number Item Description
1 Power supply • This means the power supply of fusible link or fuse.
2 Fusible link • “X” means the fusible link.
3 Number of fusible link/
fuse • This means the number of fusible link or fuse location.
4 Fuse • “/” means the fuse.
5 Current rating of fus-
ible link/fuse • This means the current rating of the fusible link or fuse.
6 Optional splice • The open circle shows that the splice is optional depending on vehicle application.
7 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-61, "Elec-
trical Units Location", PG-39, "Harness Layout".
8Splice • The shaded circle “ ” means the splice.
9 Page crossing • This circuit continues to an adjacent page.
10 Option abbreviation • This means the vehicle specifications which layouts the circuit between “ ”.
11 Relay • This shows an internal representation of the relay.
12 Option description • This shows a description of the option abbreviation used on the page.
13 Switch • This shows that continuity exists between terminals 1 and 2 when the switch is in the A
position. Continuity exists between terminals 1 and 3 when the switch is in the B position.
14 Circuit (Wiring) • This means the wiring.
15 System branch • This shows that the circuit is branched to other systems.
16 Shielded line • The line enclosed by broken line circle shows shield wire.
17 Component name • This shows the name of a component.
18 Ground (GND) • This shows the ground connection.
19 Connector • This means the connector information.
• This unit-side is described by the connector symbols.
20 Connectors • This means that a transmission line bypasses two connectors or more.
21 Wire color • This shows a code for the color of the wire.
B = Black
W = White
R = Red
G = Green
L = Blue
Y = Yellow
LG = Light Green
BG = Beige BR = Brown
OR or O = Orange
P = Pink
PU or V (Violet) = Purple
GY or GR = Gray
SB = Sky Blue
