What is wiring harness diagram?

A wire harness is a specially designed system that keeps numerous wires or cables organized. It is a systematic and integrated arrangement of cables within an insulating material. The purpose of the wiring assembly is to transmit a signal or electrical power.

What are the terminals in a wiring harness?

Terminals are used in wire harnesses to cease the conductor to a particular point, and secure and protect the connection. Generally made of metal or alloy, these devices may also be composed of silicon or carbon, depending upon the application requirement.

What are connectors in harness?

Male and female wire harness connectors serve to provide the necessary junctions between the many different elements of the wire harness to produce an efficient transmission of data, signal, or power through the system. In simplistic terms, plugs are usually male connectors and jacks are female wire harness.

Automotive cables play a crucial role in cars, mainly including the following aspects:

1. Transmission of electrical energy: The car connection line connects the power supply and electrical equipment through wires to achieve the transmission of electrical energy. This is the most basic function of car cables and the fundamental reason for their existence.

2. Signal transmission: Automotive cables can achieve signal transmission between various electrical devices, such as switch signals, sensor signals, etc. These signals are crucial for the normal operation of cars, such as engine control systems, brake systems, navigation systems, etc., all of which require signal transmission through car connectors.

3. Data transmission: With the development of automotive electronics and intelligence, car cables still need to transmit a large amount of data, such as in car entertainment systems, car networking systems, etc. These data are of great significance for improving the performance, comfort, and safety of automobiles.

4. Maintain the normal working condition of electrical equipment: The car connecting wire connects the electrical equipment to the ground to help dissipate heat, avoid overheating and damage to the electrical equipment, and prevent electromagnetic interference from affecting the normal operation of the equipment.

5. Safety protection: When there is a short circuit or leakage in the car's electrical system, the grounding wire can introduce excess current into the ground to prevent the car's electrical equipment from burning out due to overload and ensure driving safety.

6. Emergency start and charging: When the battery is low or damaged, a grounding wire can be used to connect the batteries of other vehicles to the vehicle that needs to be started or charged, achieving the functions of emergency start and charging.

7. Fault diagnosis: During the process of car maintenance, using a grounding wire can better check whether the vehicle's electrical system is working properly, thereby quickly finding and eliminating faults.
