Handbook 652 Body Electrical Diagnosis Component Connectors Components are wired into a circuit using connectors that can be disconnected to make removing and replacing components easier. The component identifier is also the connector ID number . Connector List The Connector List section of the EWD contains diagrams of every component connector in the vehicle. ( Harness-to-harness connectors are found in the Electrical Wire Routing section, discussed in detail later.) A connector diagram assigns pin numbers to each of the terminals in the connector.
The same pin numbers appear at the component ’ s circuit connections in the system circuit diagram so you can trace current flow to and through the component. NOTE Remember the Connector List did not begin appearing in the EWD until the 2000 model year. Prior to 2000, diagrams of a circuit ’ s connectors appear at the end of the system circuit diagram, in both the printed manual and on TIS. Technical Training 73
