In order to make the whole car line regular, convenient installation and protect the insulation of the wire, the whole car line on the car in addition to the high voltage line, battery cable and starter cable, generally the same area of different specifications of the wire with insulation materials such as cotton yarn or thin PVC plastic tape wrapped into bundles, known as the car wiring harness.

Wiring harness is the electrical connection between the shortest way to choose, and the same path of a number of wires with insulation wrapped up. Therefore, it is mainly composed of various colors of low-voltage wires and related link plug-ins, wiring terminals, insulation wrapping materials, etc. Automobile wiring harness can be used with the wiring harness diagram mentioned above in conjunction with the parts location diagram and circuit schematic diagram.

Don't underestimate this small car harness, can play a vital role!
