Wiring harness is one the most essential parts of the vehicle industry. A wiring harness is an organized set of wires, terminals and connectors that run throughout the entire vehicle and transmit information and electric power, thereby playing a critical role in “connecting” a variety of components. Power and information travel through this network much like the circulatory and central nervous systems of the human body. It conducts electricity for all electrical loads on a vehicle.
Wiring harnesses contribute tremendously to manufacturers’ development and advancement of vehicles around the world. Automobiles or off-highway vehicles are driven in all kinds of environments, from cities to mountain villages, in the tropics as well as in cold climates. This means wiring harnesses must offer superior durability.
There are four main steps in electrical system design: selection of component, wiring diagram, wiring harness and electrical routing. Let’s look closer into these!
