General Description
WIRING DIAGRAM

The wiring diagram of each system is illustrated so that you can understand the path through which the electric current flows from the battery.Sketches and codes are used in the diagrams. They should read as follows:

- Each connector and its terminal position are indicated by a sketch of the connector in a disconnected state which is viewed from the front.

-

The number of poles or pins, presence of a lock, and pin number of each terminal are indicated in the sketch of each connector. In the sketch, thehighest pole number refers to the number of poles which the connector has. For example, the sketch of the connector shown in figure indicates theconnector has 9 poles.

> Relays and Modules > Relays and Modules - Lighting and Horns > Exterior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions

> Page 80

Legacy L Wagon AWD F4-2.5L SOHC (2001)

- When one set of connectors is viewed from the front side, the pole numbers of one connector are symmetrical to those of the other. When these

two connectors are connected as a unit, the poles which have the same number are joined.

­Electrical Wiring Harness:The connectors are numbered along with the number of poles, external colors, and mating connections in the accompanying list.

­The sketch of each connector in the wiring diagram usually shows the (A) side of the connector. The relationship between the wire color, terminalnumber and connector is described in figure.

NOTE:

A wire which runs in one direction from a connector terminal sometimes may have a different color from that which runs in the otherdirection from that terminal.

- In wiring diagram, connectors which have no terminal number refer to one-pole types. Sketches of these connectors are omitted intentionally.

> Relays and Modules > Relays and Modules - Lighting and Horns > Exterior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions

> Page 81

Legacy L Wagon AWD F4-2.5L SOHC (2001)

- The following color codes are used to indicate the colors of the wires used.

­The wire color code, which consists of two letters (or three letters including Br or Lg), indicates the standard color (base color of the wirecovering) by its first letter and the stripe marking by its second letter.

- The table lists the nominal sectional areas and allowable currents of the wires.

When replacing or repairing a wire, be sure to use the same size and type of the wire which was originally used.CAUTION:

NOTE:

-

The allowable current in the table indicates the tolerable amperage of each wire at an ambient temperature of .40 C (104 F)

> Relays and Modules > Relays and Modules - Lighting and Horns > Exterior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions

> Page 82

Legacy L Wagon AWD F4-2.5L SOHC (2001)

- The allowable current changes with ambient temperature. Also, it changes if a bundle of more than two wires is used.

-

Each unit is directly grounded to the body or indirectly grounds through a harness ground terminal. Different symbols are used in the wiringdiagram to identify the two grounding systems.

- The ground points is shown in the wiring diagram.

All wiring harnesses are provided with a ground point which should be securely connected.NOTE:

> Relays and Modules > Relays and Modules - Lighting and Horns > Exterior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions

> Page 83

Legacy L Wagon AWD F4-2.5L SOHC (2001)

-

Relays are classified as normally-open or normally-closed. The normally-closed relay has one or more contacts.The wiring diagram shows the relay mode when the energizing circuit is .OFF

> Relays and Modules > Relays and Modules - Lighting and Horns > Exterior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions

> Page 84

Legacy L Wagon AWD F4-2.5L SOHC (2001)

-

Each connector number shown in the wiring diagram corresponds to that in the wiring harness. The location of each connector in the actual vehicleis determined by reading the first character of the connector (for example, a "F" for F8, "i" for i16, etc.) and the type of wiring harness.The first character of each connector number refers to the area or system of the vehicle.

> Page 85

Legacy L Wagon AWD F4-2.5L SOHC (2001)

SYMBOLS IN WIRING DIAGRAMS

A number of symbols are used in each wiring diagram to easily identify parts or circuits.

1. RELAY

A symbol used to indicate a relay.

2. CONNECTOR-1

The sketch of the connector indicates the one-pole types.

3. WIRING CONNECTION

Some wiring diagrams are indicated in foldouts for convenience. Wiring destinations are indicated where necessary by corresponding symbols (aswhen two pages are needed for clear indication).

4. FUSE NO. & RATING

> Relays and Modules > Relays and Modules - Lighting and Horns > Exterior Lighting Module > Component Information > Diagrams > Diagram Information and Instructions

> Page 86

Legacy L Wagon AWD F4-2.5L SOHC (2001)

The "FUSE No. & RATING" corresponds with that used in the fuse box (main fuse box, fuse and joint box).

5. CONNECTOR-2

- Each connector is indicated by a symbol.

- Each terminal number is indicated in the corresponding wiring diagram in an abbreviated form.

- For example, terminal number "C2" refers to No. 2 terminal of connector (C:F41) shown in the connector sketch.

6. CONNECTOR SKETCH

-

Each connector sketch clearly identifies the shape and color of a connector as well as terminal locations. Non-colored connectors are indicatedin 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 referring 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 onepage to the next.

A <--> A, B <--> B

10. SYMBOLS OF WIRE CONNECTION AND CROSSING

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 symbolsthroughout the text, correspond with those shown in the POWER SUPPLY ROUTING in the wiring diagram.Accordingly, using the POWER SUPPLY ROUTING and wiring diagrams permits service personnel to understand the entire electricalarrangement of a system.

Fuse/Relay Locations:

For fuse and/or relay locations refer to Starting and Charging / Power and Ground Distribution: See: Power and GroundDistribution

For component locations refer to Vehicle / Locations / Harness: See: Locations/Harness Locations Component Locations:

For ground locations refer to Vehicle / Locations / Grounds: See: Locations/Ground LocationsGround Locations:

NOTE:

To locate Connectors, Components and/or Grounds using Harness Connector Location diagram(s) use the connector's alphanumeric name [referred to in

the wiring diagram(s)] to identify the appropriate Harness Connector Location diagram. For example, the prefix letter "B" in the connector name "B-38"indicates the location is displayed in the Bulkhead Wiring Harness Connector Location diagram.
