15 Best Automotive Wiring Harness Companies

The automotive wiring harness is the main body of the network of automotive circuits. It is a connection component belonging to the electrical system of the vehicle. A wire harness is a contact terminal (connector) made of copper that is crimped to a wire or cable. The outside is then molded and pressed with an insulator or an additional metal shell. Wire harnesses are assemblies that are bundled to form a connection circuit.

The operating conditions and parameters of the car are reflected visually in the on-board computer through the wiring harness. It can be said to be the nervous system of a car. So it has traditionally been called the “blood vessel” of the car. The electronic content of the wiring harness has gradually become an important indicator for evaluating the performance of a car.

The automotive wiring harness market tends to increase or decrease in line with vehicle sales. The two largest Japanese automotive wiring harness manufacturers, Yazaki and Sumitomo Wiring Systems, have a combined market share of over 50%.

In addition to Fujikura and Furukawa Electric, the Japanese harness companies have a market share of more than 60%; in addition, the three Korean harness companies Kyungshin, Yura, and Yuzhin have a share of nearly 15%; the remaining market share is held by European and American LEONI and Aptiv. (The remaining market share is held by European and American companies. Such as LEONI, Aptiv, Lear, PKC, Kromberg & Schubert, Coroplast, and Draexlmaier.)
