How to divide the entire vehicle wiring harness

The wiring harness of the vehicle is generally divided according to the position where the harness is located, such as the engine compartment, the cockpit, the chassis, the canopy, the door, the trunk. The whole vehicle wiring harness can be roughly divided into four categories: front wiring harness, body wiring harness, parking harness and door harness.

Front wiring harness: including engine compartment wiring harness, headlight harness, steering light harness, engine harness, fuel injection rail harness, shifting mechanism harness, engine grounding harness, starting motor power cable harness, battery grounding wire harness, generator harness, etc.

Body harness: including instrument panel wiring harness, air conditioning harness, airbag wiring harness, floor harness, ceiling harness, etc.

Wiring harness at the rear: trunk wiring harness, taillight harness, reversing radar harness, etc.;

Door harness: left front door harness, right front door harness, left rear door harness, right rear door harness, back door harness, etc.

Of course, there are many ways to divide the wiring harness of the whole vehicle, and it cannot be generalized in this way. If the engine is centered or rear, the wiring harness such as the harness and the engine grounding harness will not belong to the front wiring harness.

Similarly, we classify harnesses such as taillight harnesses, reversing radar harnesses, trunk wiring harnesses as part of the floor harness, classify the air conditioning harness as part of the instrument panel harness, and classify the fuel rail harness as part of the engine harness.

Here, the wire harness factory should emphasize that since the airbag and the seatbelt involve the safety of the driver and the occupant, it is recommended to separate the airbag wire harness from each other and not merge it into a wire harness with other wire harnesses, and design and power distribution in the whole vehicle. Production, processing, transportation, assembly and other aspects must be considered separately.
