ARNING REGARDING THE SERVICING OF VEHICLES FITTED WITH SRS AIR BAGS AND SEATBELTS WITH PRE-
TENSIONERS
W arning
1. Improper servicing or maintenance of any SRS air bag or pre-tensioner fi\
tted seatbelt component, or related parts, could cause serious injury through the SRS air bag or pre-tensioner fitt\
ed seatbelt being activated unintentionally
or accidentally.
2. The SRS-ECU, the driver’s side air bag module, the passenger side air bag module, the pre-tensio\
ner fitted seatbelts and the clock spring, should be removed if there is a chance o\
f them being affected by heat during
painting work.
• 93ºC and above: the SRS-ECU, the driver’s air bag module, the passenger’s air bag module and the clock spring should be removed.
• 90ºC and above: the pre-tensioner fitted seatbelts should be rem\
oved.
3. Servicing and maintenance of any SRS air bag or pre-tensioner fitted sea\
tbelt components, or related parts, must be performed by an authorized Mitsubishi dealer.
4. Servicing and maintenance of any SRS air bag or pre-tensioner fitted sea\
tbelt components, or related parts, must only be undertaken after this service manual (specifically Section 52B-\
SRS air bags) has been carefully studied.

Evolution IX
Foreword
This manual is designed to facilitate inspection and
repair work relating to the electrical wiring system in the
’05 Lancer Evolution IX, and contains layout diagrams
which give a three-dimensional representation of the
electrical wires and connectors of the various parts of
the vehicle, as well as circuit diagrams indicating the
wiring design for different systems, and diagrams
showing the points at which each individual component
is installed.
When inspecting or repairing electrical parts, this
manual should be used in conjunction with the related
documents listed on the following pages, if necessary.
This manual contains various different types of wiring
diagrams and circuit diagrams, but it should be
remembered that these may not always coincide with
the exact specifications of each individual vehicle.
This manual is based on the vehicle specifications as
of March 2005.
Please note that future vehicles may not match the
contents of this manual completely, due to changes
in specifications, or the like.
The units shown in this manual are the standard
international SI units. Conventional units are not
included.

How to Read the Wiring Diagrams
Composition and Contents of Wiring Diagrams
1. This manual contains wiring layout diagrams, individual part installation positions, circuit diagrams and an index.
2. All specifications, including those relating to optional equipment, are given in each section. Accordingly, some of the
specifications may not apply to a particular vehicle.

GENERAL INFORMATION - HOW TO READ THE WIRING DIAGRAMS0-3
Reading Layout Diagrams
The wiring layout diagrams give a clear and simple illustration of the connector positions and the routing of the wiring
harnesses at different points in the actual vehicle.
Indicates connector number.
The same connector number is used in the circuit diagrams, so that connector positions can be located easily.
The initial letter indicates the installation position of the connector, and the number that follows is the unique number for that
connector. In principle, the connectors are numbered in clockwise order in each layout diagrams, starting from the top left-hand side.
Example : A – 19Unique connector number (serial number)
Connector location code
A: Engine compartment D: Floor / Roof
B: Engine / Transmission E: Door
C: Instrument panel F: Tail gate
Indicates earth point.
The same earth numbers are used in the circuit
diagrams, so earth points can be located easily.
For details of earth points, refer to Section 2,
"Individual Part Installation Positions – Earth".
Indicates name of harness
Shows section covered with
corrugated tube.
The * symbol shows a standard
harness mounting point.
Indicates the external colour of the harness.
(Black, unless specified otherwise.)
R : Red
Y: Yellow
The number of connector pins and the connector colour (except
cream colour)* are indicated, so that they can be located easily.
Example : 2 – Black
*^: Typical connector colours:
Black, grey, red, blue, yellow, green, brown, etc.
Colour of connector pins(Cream colour, unless specified
otherwise)
Number of connector pinsA-15 (2) Fog lamp (RH)
A-16 (2-Black) Windshield washer motor
A-17 (2-Black) Headlamp (RH)
A-18 (2-Brown) Horn (LO)
A-19 (2-Green) Dual pressure switch
Indicates the device to which the
connector is connected.

GENERAL INFORMATION - HOW TO READ THE WIRING DIAGRAMS0-4
Reading Circuit Diagrams
These diagrams show the circuits for each system, from the fuse or fusible link to the earth. In principle, the power supply is
shown at the top and the earth at the bottom, to make it easier to understand the flow of current in the circuit.
The circuit diagrams show a state where none of the switches, etc. are operating.
Indicates power take-out
point.Indicates connector No. The same number is used in the layout
diagrams. Connector numbers shown inside a rounded box indicate
connector symbols that are listed together at the bottom of the page.
Connector numbers that are not shown inside a rounded box indicate
components that are incorporated into the harness.
Indicates that the terminal is
connected via a plate inside
the relay box.
Each circuit diagram is divided into
blocks shown on separate pages.
This number indicates the block.
Indicates the harness branch
point. This number matches the
branch numbers in the other
circuit diagrams.
Indicates the number of the circuit
to which the branch connects.
Indicates the power supply
within the control unit. If no
voltage is indicated, then it is
the battery voltage.
An "X" at the end of a connector
number shows that it is part of the
centralized relay. For more
information, refer to the section
covering the Centralized Junction.
Indicates that circuit diagram
continues at [A] in Block [2].
Indicates the connector symbol,
listed in the order of the connector
numbers in the circuit diagram.
Indicates the operating
conditions of the coolant
temperature switch, etc.Indicates shield
wire.An upward arrow indicates that
the current flows from bottom to
top in the diagram.

Indicates input / output to
and from control unit
(direction of current flow).
Input Output Input/Output
Indicates a wiring connector inside a device,
which is not shown in the layout diagrams.
Example :
Indicates a connector
located inside a
device, numbered in
order starting from 1.
Indicates the number of the connector
shown in the layout diagram.
Indicates that these are the same
intermediate connector.
Indicates that the diagram
continues from section [A] in
block [1].
Indicates the terminal No.
If two or more connectors are
connected to the same device, a
broken line between parts indicates
that the same connector is used.
The two-way arrow shows that
current can flow downwards or
upwards, under the control of
the ECU.
Indicates a harness junction point
where the wire changes colour or
diameter.
Indicates an intersection
where the wires are not
connected.
Indicates an intersection
where the wires are
connected
Indicates the representative earth
point on the vehicle body for that
circuit. (This number matches that of
the earth point in the layout diagrams
and the diagrams of individual part
installation positions.)
Indicates a spare connector, if the
corresponding device is not
installed, due to the vehicle
specifications.Indicates the connector part number given in
the harness repair manual. A number in
( ) indicates the part number of the connector
that corresponds to a connector symbol.
