MRFOREWARD
This manual contains information about the mainchanges in the 2004 Lancer Evolution VIII MR. It only covers those points that are different from theprevious model. Therefore, when inspecting orrepairing electrical parts, this manual should be used inconjunction with the related documents listed on thefollowing pages, if necessary. This manual contains various different types of wiringdiagrams and circuit diagrams, but it should beremembered that these may not always coincide withthe exact specifications of each individual vehicle. This manual is based on the vehicle specifications as ofFebruary 2004.Please note that future vehicles may not match thecontents of this manual completely, due to changes inspecifications, or the like. The units shown in this manual are the standardinternational SI units. Conventional units are notincluded.

Cautionary Note regarding servicing of vehicles fitted with SRS airbags and/or seatbelts withpre-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. Thisapplies to the SRS-ECU, airbag modules (driver’s sear and front passenger’s seat), clock springs, front impactsensors, 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 thesesystems, 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 andthoroughly, before inspecting or servicing the component parts of the SRS airbag system or seatbelt pre-tensionersystem, and parts relating to these systems.
