If a connector is referenced twice in a wiring diagram for the same circuit, what does that imply about the connector?

• A. there are two terminals in the connector used by the circuit.
• B. the diagram has an error.
• C. the connector houses two separate circuits.
• D. the connector is a ground point.

Answer: (A)

When a wiring diagram shows the same circuit connected to the same connector at two different points, it means the connector has more than one terminal used by that circuit. A multi-pin connector is designed to carry multiple wires, and sometimes the same signal is routed through two pins within the same housing to pass through the harness or share current. So seeing the same circuit reference on two pins simply indicates two terminals are used in that connector for that circuit, not an error, a ground point, or two separate circuits. If it were a ground, you’d usually see a ground symbol; if it were two different circuits, you’d expect different circuit identifiers or wire designations.
