Page 3 A INTRODUCTION This manual consists of the following 13 sections: Section Description INDEX Index of the contents of this manual. INTRODUCTION Brief explanation of each section. HOW TO USE THIS Instructions on how to use this manual. MANUAL TROUBLE– Describes the basic inspection procedures for electrical circuits. SHOOTING ABBREVIATIONS Defines the abbreviations used in this manual.
Page 4 HOW TO USE THIS MANUAL B This manual provides information on the electrical circuits installed on vehicles by dividing them into a circuit for each system. The actual wiring of each system circuit is shown from the point where the power source is received from the battery as far as each ground point.

Page 6 [A] : System Title [H] : Indicates the wiring color. Wire colors are indicated by an alphabetical code. [B] : Indicates a Relay Block. No shading is used and only the Relay Block No. is shown to distinguish it B = Black W = White BR = Brown from the J/B...
Page 7 B HOW TO USE THIS MANUAL System Outline Current is applied at all times through the STOP fuse to TERMINAL 2 of the stop lamp SW. When the ignition SW is turned on, current flows from the GAUGE fuse to TERMINAL 8 of the light failure sensor, and also flows through the rear lights warning light to TERMINAL 4 of the light failure sensor.
Page 8 [O] : Explains the system outline. [P] : Indicates reference pages showing the parts locations in the system circuit on the vehicle. Example : Code ”H4” (Light Failure Sensor) is on page 36 of the manual. * The first character of the code indicates the alphabetical code allocated to the wire harness, and the second character indicates the serial number of the parts connected to the wire harness.
Page 9 B HOW TO USE THIS MANUAL The ground points circuit diagram shows the connections from all major parts to the respective ground points. When troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify the problem ground quickly.
Page 10: Power Source
The ”Current Flow Chart” section, describes which parts each power source (fuses, fusible links, and circuit breakers) transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully understood.
