COMPOSITION AND CONTENTS OF WIRING DIAGRAMS


In each section, all specifications are listed, including optional specifications. Accordingly, some specifications may not be applicable for individual vehicles.
Section
 Basic contents
Component locations
 Locations are shown for each point of inspection connectors, fusible links, fuses, earth cable, earth etc. In the part’s lists, parts are listed in alphabetical order.
Configuration diagrams
 Connector locations and harness wiring configurations on actual vehicles are illustrated.
Circuit diagrams
 Circuits from power source to earth are shown completely, classified according to system. There is a main division into power source circuits and circuits classified by system.

  • Junction block (J/B)
    The entire circuit for the junction block is described, because only the part of the junction block needed is normally shown in each circuit diagram.
  • Joint connectors (J/C)
    The internal circuits for all joint connectors are described, because only the part needed is shown in each circuit diagram.
  • Power source circuits
    Circuits from the battery to fusible link, fuse, ignition switch, etc. are shown.
  • Circuits classified by system
    For each system, the circuits are shown from fuse to earth, excluding the power source sections.
