Wiring Harness: Function and Importance in Car Electrical Systems
Wiring Harness or harness cable is one of the proofs of technological advancement that has penetrated the automotive world, especially in the car's electrical system. So what is the function of the harness cable? And why is its role so important in the car's electrical system? For more details, please pay attention to the following review.
What is Wiring Harness?
Wiring Harness is a cable component that is interconnected in the vehicle system and plays an important role in channeling electrical current from the power source to devices or components in a system that is listed in the car.
Function of Wiring Harness
In general, Wiring Harness functions to connect components in a car system with the car's electrical system so that all systems in the car can function properly and optimally.
However, specifically, Wiring Harness functions according to its type. The types are as follows.
1. Main Harness
Main Harness is a type of Wiring Harness that has the main function of connecting all electrical systems and components of the car.
2. Engine Harness
Functions as a connector between all fuel injection components and the ignition system in the car engine.
3. Harness Body
Functions to distribute electricity to other Harness parts such as the lighting system, audio system, locking system, and door electrical system.
4. Chassis Harness
Functions as a connector between all systems and components inside the car cabin. Therefore, Chassis Harness is located at the bottom of the car.
5. Sensor Harness
Functions as a connector between sensors located in the car, such as ABS sensors, temperature sensors, oxygen sensors, and other sensors.
6. Instrument Panel Harness
Functions as a controller for various components in the car, such as tape or radio, AC, speedometer to starter.
7. Speedometer Harness
Functions as a connector between the speedometer and controls, such as distance, fuel, fuel amount, and so on.
8. Lamp Harness
Functions to channel electrical current to the car's lighting or lamp section.
9. Battery Cable Harness
Functions to supply electrical current from the battery to the car's electrical devices.
Why is Wiring Harness Very Important for the Car's Electrical System?
For those of you wondering why Wiring Harness is very important for the car's electrical system, it is because Wiring Harness can simplify the process of installing cables in the car. In addition, Wiring Harness can also enhance the security and safety of the car from the risk of fire caused by electrical short circuits.
This can be realized because Wiring Harness is a series of cables bundled together, making the cable components more robust and less flexible, as well as more resistant to vibrations, moisture, or scratches that can cause abrasions.
Tips for Properly Maintaining Wiring Harness
To ensure that the Wiring Harness in your car does not wear out easily, you need to maintain it properly. You can check the condition of the connectors on the Wiring Harness to ensure they are free from dirt and dust. Avoid exposing the Wiring Harness to direct air or sunlight as it can cause corrosion or cable expansion.
If the Wiring is damaged, immediately replace it by seeking help from an expert, such as requesting assistance from a Daihatsu official workshop mechanic. Because the installation of Wiring Harness cannot be done independently, as any mistakes can cause the car to malfunction completely and lead to serious damage to important components and systems in the car.
