Handbook 652 Body Electrical Diagnosis Junction Connector Because it is considered a component, the junction connector ’ s connectors are found in the Connector List. Connectors When the junction connector has more than one connector, the connector IDs in the system circuit diagram include a circled letter shown at each pin to indicate which connector it is in. A second diagram uses connecting lines between the terminals to indicate which terminals are wired together inside the junction connector. Within the connector, these terminals are electrically connected when the parts are assembled. 82 Technical Training
