This manual contains information about the main
changes in the 2004 Lancer Evolution VIII MR.
It only covers those points that are different from the
previous model. Therefore, 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
February 2004.
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.

Cautionary Note regarding servicing of vehicles fitted with SRS airbags and/or seatbelts with
pre-tensioner systems.
Warnings:
1. Incorrect inspection or servicing of a component part of the SRS airbag system or seatbelt pre-tensioner system, or
a part relating to these systems, may cause accidental operation (deployment) of the SRS airbag or seatbelt pre-
tensioners, or may cause these systems to be disabled, leading in either case the risk of serious injury.
2. If parts may be affected by heat during painting operations, then those parts must be removed in advance. This
applies to the SRS-ECU, airbag modules (driver’s sear and front passenger’s seat), clock springs, front impact
sensors, side impact sensors, and pre-tensioner seatbelts.
• 93ºC or above : SRS-ECU, airbag modules (driver’s sear and front passenger’s seat), clock springs, front impact
sensors, side impact sensors
• 90ºC or above : Pre-tensioner seatbelts
3. The component parts of the SRS airbag system or seatbelt pre-tensioner system, and parts relating to these
systems, must always be inspected and serviced by a Mitsubishi dealer.
4. Service personnel must read the relevant service manuals (particularly, Section 52B – SRS Airbags) carefully and
thoroughly, before inspecting or servicing the component parts of the SRS airbag system or seatbelt pre-tensioner
system, and parts relating to these systems.
