Wire Harness Knowledge Base

The wiring harness is the wiring part that connects the electrical equipment in the circuit, and is composed of an insulating sheath, wiring terminals, wires, and insulating wrapping materials.

1. Wire harness

In order to facilitate installation and maintenance, and to ensure that electrical equipment can work under the worst conditions, the wires of different specifications and different colors used in the electrical equipment of the whole vehicle are arranged in a reasonable manner, and they are integrated, and the wires are bundled with insulating materials.Bundles, which are complete and reliable.

2. Normal selection of wire cross-sectional area and color code

1) Correct choice of wire cross-sectional area

The electrical equipment on the car selects the cross-sectional area of the wire used according to the size of the load current.Electrical equipment that works for a long time can choose 60% of the actual current carrying capacity of the wire; electrical equipment that works for a short time can use 60%-100% of the actual current carrying capacity of the wire.

2) Selection of wire color code

In order to facilitate identification and maintenance, the wires in the wiring harness are in different colors.

For the convenience of labeling in the circuit diagram, the colors of the wires are indicated by letters, and the colors of their representatives are noted in each circuit diagram.
