Automotive wiring harness is the core component of the automotive electrical system, responsible for the transmission of power, signals and data to the vehicle's various electronic devices and systems. It is composed of wires, connectors, terminals, insulating materials, etc., to ensure the normal operation of the vehicle electrical system.
Features of car wiring harness
1. Power transmission : Provide power for various electrical equipment of the vehicle (such as engine, lights, audio, etc.).
2. Signal transmission : Transmit signals between sensors, control units and electronic devices (such as speed signals, temperature signals, etc.).
3. Data communication : Support vehicle network (such as CAN bus, LIN bus) data transmission, to achieve the communication between the electronic control unit (ECU).
4. Protection and insulation : Through insulation materials and protective design, to prevent wire wear, short circuit or affected by the external environment (such as high temperature, humidity).
Automotive wiring harness classification
1. Classification by voltage :
- Low voltage wire harness : Used in the electrical system of traditional fuel vehicles (such as lights, audio, instrument panel, etc.).
- High voltage wire harness : High voltage batteries, motors and charging systems for new energy vehicles (such as electric vehicles, hybrid vehicles).
2. Classification by function :
- Engine wire harness : Connects the engine control unit (ECU), sensors and actuators.
- Body wire harness : Connect body electronics (e.g. lights, Windows, door locks, etc.).
- Dashboard wire harness : Connects the dashboard, display and control system.
- Chassis wire harness : Connect chassis control systems (such as ABS, ESP, etc.).
- Charging wire harness : Charging interface and battery management system for electric vehicles.
3. Sort by location :
- Front cabin wire harness, cab wire harness, door wire harness, trunk wire harness, etc.
