Mitsubishi SPACE WAGON 1998 Wiring Diagram – Factory Specs

Description

This is the factory Mitsubishi SPACE WAGON 1998 Wiring Diagram manual. If you’re working on electrical problems without this, you’re wasting time and risking damage. I’ve seen too many DIYers throw parts at a no-crank because they didn’t have the correct circuit paths. This manual stops that. It’s 165 pages of OEM wiring data, straight from Mitsubishi Motors Corporation. No aftermarket shortcuts. No missing ground points.

Get the Right Wiring Diagram for Your 1998 Mitsubishi SPACE WAGON

Page 2 of this manual shows the preface and tells you exactly how the document is organized. You get four main sections: how to read wiring diagrams, harness configuration diagrams, location of individual parts, and circuit diagrams. Every section is laid out with the same logic the factory techs used. The manual covers all models and option packages, but note on page 4 it says some specs may not apply to your specific vehicle—so always verify with a multimeter.

Interpreting Wiring Diagrams – Section 1 Essentials

Section 1 teaches you how to interpret the symbols Mitsubishi uses. You’ll find wire color codes (B for black, W for white, etc.), ground connection marks, and abbreviations. If you don’t know the difference between a fusible link and a regular fuse, this section clears that up. The manual assumes you have basic electrical tools: multimeter, test light, jumper wires. It does not assume you know everything—it teaches you.

Harness Configuration – Section 2 Layout

Section 2 shows the harness routing diagrams. You see where each connector sits and how the wire bundles snake through the firewall, under the dash, and into the engine bay. Need to find the ECU connector location? It’s mapped out here. For related models, check out Mitsubishi Outlander 2004 Configuration Diagrams for comparison. The configuration diagrams are drawn from the perspective of standing at the front of the vehicle—something aftermarket manuals get wrong constantly.

Component Locations – Section 3 Maps

Section 3 lists every relay, control unit, sensor, solenoid, diode, inspection connector, and ground point alphabetically. If the manual says “fuel pump relay” under the dash, you’ll see the exact position in a table. This saves hours of probing. The positions are keyed to the harness diagrams, so you can cross-reference. For another take on wire routing, Mitsubishi Lancer Evolution Viii Simplified Wiring System offers a different approach, but this manual stays factory exact.

Circuit Diagrams – Section 4 Diagnostics

Section 4 contains the actual circuit diagrams. Each circuit is isolated: you see power flow from the battery through ignition, fuses, switches, relays, and finally to the component. Ground paths are shown with the specific ground point mark. If your interior lights don’t work but the dome fuse checks good, this section helps you trace the entire circuit without guessing. For complementary diagrams, Mitsubishi Lancer Evolution VIII Circuit Diagrams covers a related platform.

Why Factory Wiring Data Beats Aftermarket

Aftermarket wiring diagrams often combine multiple years or skip optional circuits. This manual is printed by Mitsubishi Motors Corporation in September 1998 and includes every option available at that time. The wire color codes match the actual vehicle—no reinterpretation. You get the same information dealer techs had. For background on how these standards evolved, Automotive Wiring explains the basics, and Automotive Industry Overview covers manufacturing context. But for your 1998 SPACE WAGON, nothing beats the original.

Frequently Asked Questions

Does this manual cover all SPACE WAGON models for 1998?

Yes, it covers all models and optional equipment.

Can I use this manual for a 1999 SPACE WAGON?

The manual is titled SPACE WAGON ’99 and published in 1998. It covers the 1999 model year. However, production changes after September 1998 are not included. Check your vehicle build date. If it’s after that, you may need a later revision. For electrical diagnosis, 90% of the circuits will be identical. The manual lists options that may not be on your vehicle, as noted on page 4. Use it as a base, but verify with a multimeter.

What tools do I need to use this manual?

A multimeter, test light, and a few jumper wires. The manual assumes you have basic electrical tools.

Does this manual include pinout diagrams for the ECU?

Yes, Section 2 and Section 4 include connector pinouts and wire colors for the ECU and other modules. You’ll find the connector locations in Section 3.
