What is the Automotive wiring harness? Cars are large, with an average length of about 4 meters. Despite this, a car is assembled from more than 10,000 independent parts that cannot be disassembled, and most of these parts are small.
The wiring harness in a car is responsible for many functions in the car, such as airbags, ABS brakes, signal lights, and engines. Without the wiring harness, these functions would not be possible.
Therefore, we should fully understand the role of the car wiring harness. Next, we will explain the role and importance of the car wiring harness.
What is an automotive wiring harness?
The automotive wiring harness is the network body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the contact terminal (connector) made of copper material, which is crimped with the wire and cable, and then the insulator is plastic-pressed or the metal shell is added to form a component that connects the circuit.
Simply put, the automotive wiring harness assembles cables, connectors, terminals and wires to transmit electricity in the 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 automotive wiring harness is a key component of any car engine. Without them, the current cannot reach the different electrical components of the car.
The ignition system of the car, such as the starter, chassis and alternator, all require electricity. Without the automotive wiring harness to transmit them, they cannot get this electricity.
But for the car, it is not enough to just have an automotive wiring harness. The wires and terminals must also be properly connected to the electrical components.
Understanding this connection is to understand the different wiring harness circuits.

Since car wiring harnesses connect to different electrical components, they have different connection circuits.
These circuits have different uses. A standard car circuit has 12.
Circuits include:
Dashboard lights
Instruments
Signal lights
Heating and air conditioning
Horn
Parking lights
Radio
Brake lights
Tail lights
Turn signals
Wipers
From their names, you can easily understand the function of each circuit.
However, many high-end vehicles have wiring harnesses with more than 12 circuits. Some have 18, and some have 24. These extra circuits are important because the vehicle is equipped with more electrical components.
If a car has 18 circuits, you will find the following as extra circuits:
Electric fuel pump
Electric fan
High-mounted parking lights
Two power locks
Radio B+ memory
But if the car has 24 circuits, in addition to the 18, these are the extra circuits:
Dome light
Trunk light
Glove box light
Clock
Under hood light
What are the advantages of automotive wiring harnesses?
Having an automotive wiring harness in your car is always better than not having one. Here are some of the benefits they bring:
Less occurrence of short circuits: With automotive wiring harnesses, there is less chance of short circuits in the circuits. Why? Because the wiring harness assembles multiple wires into well-arranged bundles. These bundles are not flexible but not loose.
Quick setup: Installing a wiring harness can take a long time with many wires and circuits to be connected. However, with automotive wiring harnesses, there is only one unit to connect and all the wires will work. In addition to simplifying the setup, you can also avoid making wrong connections.
Better fuel usage: Installing an automotive wiring harness will ensure that the car optimizes fuel usage. In the long run, you can save money on gas.
More durable: Cars often need to endure harsh environments. There are only rare examples such as cold winter weather, downpours, and heat waves. In such conditions, automotive wiring harnesses still function. These harnesses are made of sturdy materials that do not break easily.
