What is the wiring harness of a car? The car is very large, with an average length of about 4 meters. Nevertheless, a car is probably made up of more than 10000 individual parts that cannot be disassembled, and most of these parts are very small.

The wiring harness in the car is responsible for many functions in the car, such as airbags, ABS brakes, signal lights and engines, and many other important functions in the car. None of these functions would be possible without the wiring harness.

Therefore, we should fully understand the role of automotive wiring harness. Next, we will explain the role and importance of automotive wiring harnesses.

What is automotive wiring harness?

The automobile wiring harness is the main body of the automobile circuit, and there is no automobile circuit without the wiring harness. Wire harness refers to the contact terminal (connector) punched from copper material and crimped with the wire and cable, and then plastic insulator or metal shell is added to the outside, and the wiring harness is bundled to form a connected circuit component.

In simple terms, automotive wiring harnesses assemble cables, connectors, terminals and wires to transmit electricity in a car.

In the past, cars were purely mechanical and could run without electricity. However, driving a modern car without electricity would be a miracle.

Therefore, the car wiring harness is a key component of any car engine. Without them, the current cannot reach the different electrical parts of the car.

The ignition system of a car, such as the starter, chassis, and alternator, all require electricity. If there is no automotive wiring harness to transmit them, they cannot obtain this power.

But for cars, it is not enough to have a car wiring harness. The wires and terminals must also be properly connected to the electrical components.

To understand this connection is to understand the different wiring harness circuits.
