Which term refers to a device that connects electrical wires in a vehicle?

• A. Connector
• B. Harness
• C. Relay
• D. Fusible link

Answer: (A)

The idea here is identifying the device that physically links electrical wires in a vehicle. A connector is the component designed to join two or more conductors by mating two halves, creating a complete circuit that can also be separated for service. Automotive connectors come in paired genders and are built to withstand vibration and environmental exposure, making reliable, modular connections throughout the wiring system. This differs from a harness, which is simply the organized bundle of wires; a relay, which acts as an electrically controlled switch to turn circuits on or off; and a fusible link, which serves as a protective fuse that melts open under excess current. So, the term for a device that connects electrical wires is the connector.
