[C]: ( ) is used to indicate different wiring and
connector, etc. when the vehicle model, engine
type, or specification is different.
[D]: Indicates related system.
[E]: Indicates the wiring harness and wiring harness
connector. The wiring harness with male terminal is

Compartment, ºIº for the Instrument Panel and
Surrounding area, and ºBº for the Body and
Surrounding area.
When more than one code has the first and second
letters in common, followed by numbers (e.g, IH1,
IH2), this indicates the same type of wiring harness
and wiring harness connector.
[F]: Represents a part (all parts are shown in sky blue).
The code is the same as the code used in parts
position.
[G]: Junction Block (The number in the circle is the J/B
No. and the connector code is shown beside it).
Junction Blocks are shaded to clearly separate
them from other parts.
3C indicates
that it is inside
Junction Block
No.3 Example:

[H]: When 2 parts both use one connector in common,
the parts connector name used in the wire routing
section is shown in square brackets [ ].[I]: Indicates the wiring color.
Wire colors are indicated by an alphabetical code.
B = Black W = White BR = Brown
L = Blue V = Violet SB = Sky Blue
R = Red O = Orange LG = Light Green

Engine Room, ºIº for the Instrument Panel, and ºBº
for the Body).
The Location of splice Point I 5 is indicated by the
shaded section.
[K]: Indicates a shielded cable.
[L]: Indicates the pin number of the connector.
The numbering system is different for female and
male connectors.
Example :

[M]: Indicates a ground point.
The first letter of the code for each ground point(s)
indicates the component's location, e.g, ºEº for the
Engine Compartment, ºIº for the Instrument Panel
and Surrounding area, and ºBº for the Body and
Surrounding area.

B HOW TO USE THIS MANUAL
Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop light SW.
When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows
through the rear lights warning light to TERMINAL 4 of the light failure sensor.
STOP LIGHT DISCONNECTION WARNING
When the ignition SW is turned on and the brake pedal is pressed (Stop light SW on), if the stop light circuit is open, the current
flowing from TERMINAL 7 of the light failure sensor to TERMINALS 1, 2 changes, so the light failure sensor detects the
disconnection and the warning circuit of the light failure sensor is activated.
As a result, the current flows from TERMINAL 4 of the light failure sensor to TERMINAL 11 to GROUND and turns the rear lights
warning light on. By pressing the brake pedal, the current flowing to TERMINAL 8 of the light failure sensor keeps the warning
circuit on and holds the warning light on until the ignition SW is turned off.

Junction Connector
Short Terminal Same ColorJunction connector (code: J1 to J40) in this manual include a short
terminal which is connected to a number of wire harnesses. Always
perform inspection with the short terminal installed. (When
installing the wire harnesses, the harnesses can be connected to
any position within the short terminal grouping. Accordingly, in
other vehicles, the same position in the short terminal may be
connected to a wire harness from a different part.)
Wire harness sharing the same short terminal grouping have the
same color.

B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.
