How to Read and Use Circuit Schematics | Diagram Information
Connector Identification And Wire Harness Routing
If there is no photo number below or beside a component name or a connector, ground, or terminal number, look up that name or number in the
appropriate connector identification Chart. The chart lists how many cavities it has, where it's located, and what it connects to. The related
illustration shows the connector's location on the harness and the harness routing.
Shared Circuits
Other circuits may share power or ground terminals or wiring with the circuit shown. A wire that connects one circuit to another, for example, is
cut short and has an arrowhead at the end of it pointing in the direction of current flow. Next to the arrowhead is the name of the circuit or
component which shares that wiring. To quickly check shared wiring, check the operation of a component it serves. If that component works, you
know the shared wiring is OK.
Power Distribution Schematics
Power Distribution schematics show how power is supplied from the positive battery terminal to various circuits in the car. Refer to the Power
Distribution section to get a more detailed picture of how power is supplied to the circuit you're working on.
