Automotive wiring harness, also known as a wire loom or cable assembly, is an assembly of electrical cables or wires that transmit signals or electrical power in automobiles. The wire harness is a critical component of modern automobiles as it connects various electrical and electronic devices such as sensors, lights, and control modules to the vehicle's power supply and data network. The harness is typically made up of multiple wires or cables that are bound together and protected by sheaths or sleeves. The wiring harness is designed to withstand the harsh environment of a vehicle's engine compartment, including exposure to heat, moisture, and vibration.
