Assembly of electrical wiring harness
The electrical principle design of hunting vehicle wiring harness is an important design content in automobile wiring harness design. This is related to the realization of the performance of the various electrical appliances of the vehicle and the effective feedback of the functions. The design content of the electrical principle covers the distribution of the power supply of the whole vehicle. The principle analysis of the whole vehicle electronic control unit, the distribution of the whole vehicle grounding, the selection of wire harness materials-wires / relays / fuses. This series mainly talks with you about the basic content of electrical principle design and general design principle requirements.

Electricity systems usually have 5 modes and distributed electric equipment: Battery: Generally it is a safety or important part of a car. It is mainly used for the storage of components, controllers, clocks, audio systems and other components required by logic requirements such as regulations, safety, and comfort. Such as engine ECU module, BCM module, Airbag module, ABS module, Sunroof module, Air conditioning control unit, sound system, meter, TCU module, Anti-theft system, starter, Oil pump, Blower, Glass elevator, Fog lights, Indoor lights, Luggage compartment lights, Brake lights, Headlights, Position lights, Door lights, speaker, Diagnostic port, ESC seats, Main relay power supply, etc.;

IG2: The ignition key is in the ON position and provides power to the load. When the ignition key is in the start position, the IG2 power supply is cut off; Generally, it is provided to high-power loads that will not affect safety and power in an instant, such as blower control power supply, BCM module, wiper washing, post defrosting, etc.;
ACC: All auxiliary equipment to cut off the power when the engine is started;
Start: control power supply for starter or starter relay;
PREV:Toy wiring harness for electronic wire connection
NEXT:Buzzer wire harness manufacturer
