An automotive wiring harness combines numerous electric wires for a complete electric power supply and signal transmission. It includes connections, terminals, and seals made of thermoset or thermoplastic materials to shield the wires and cables from the abrasive outside environment.

The market worth of automotive wiring harness in 2021 was USD 49.04 billion, and it will be worth USD 74.46 billion, growing at a 4.75% CAGR during the forecast period. 

Some key factors propelling the growth of the automotive wiring harness market include increasing consumer demand, the manufacturing sector’s rapid expansion, the presence and development activities of vehicle OEMs, and increased adoption of advanced vehicle technologies due to an increase in per capita income. Furthermore, the importance of wire harness is increasing across the automotive industry due to the electrification of vehicles and the preference for minimal human effort. The increasing integration of technological devices has significantly impacted the market’s growth within automobiles to provide greater safety features.

Market Dynamics


The need for the automotive wire harness will be driven by the desire for improved safety features, including autonomous, emergency braking, blind-spot detection, lane departure warning system, and forward-collision warning system to prevent accidents and loss of life. Along with safety, the market will expand due to consumer desire for infotainment & telematics technologies that make it easier to use items like head-up displays, cameras, GPS, and other devices.


The car has a number of electrical issues, including battery problems, light problems, alternator problems, front and rear light malfunctions, and ignition problems, which are occasionally caused by wiring harness problems. The wiring harness can occasionally flex due to quickly varying surroundings, such as sudden swings from extremely cold to extremely hot temperatures. These issues can significantly reduce the lifespan of the wiring harness and cause it to deteriorate.


The overall number of automobile wire harnesses is growing every day due to the sophisticated technologies’ continued expansion of vehicle features. The industry predicts that the increase in tax benefits and incentives offered by governments worldwide is also boosting the total demand for electric vehicles, which will present the market with plenty of prospects in the future.

Market Segmentation 

By material, the market is segmented into copper, aluminum, and others. In 2021, the copper segment ruled the market with the largest revenue share of 55%.
