Automotive Harness

The wiring harness is the combination of electrical cables, or assembly of wires, that connects all electrical and electronic (E/E) components in the automotive vehicle, like sensors, electronic control units, batteries, and actuators. The wiring harness handles the energy and information flow within the E/E system to fulfill primary car functions, such as steering and braking as well as secondary car functions, such as ventilation and infotainment.
