The global automotive wiring harness market size was valued at USD 38.69 billion in 2020 and is projected to reach USD 64.73 billion by 2028 from USD 46.87 billion in 2021, growing at a CAGR of 4.7% during the forecast period. Based on our analysis, the global market exhibited a decline of -17.3% in 2020 as compared to the average year-on-year growth during 2017-2019. The global impact of COVID-19 has been unprecedented and staggering, with automotive wiring harness witnessing a negative demand shock across all regions amid the coronavirus crisis. The rise in CAGR is attributable to this market’s demand and growth, returning to pre-pandemic levels once the pandemic is over.

An automotive wiring harness is an electrical and electronic assembly of several automobile components that plays a vital role in connecting all electronic and electrical components for sensor signals, power supply, and transmitting data for improving vehicle performance. The assembled components include electrical devices, heating, ventilation, air conditioning (HVAC) systems, speed sensors, and other electronic components. Further, increasing the integration of electrical and electronic systems into automobiles to offer enhanced safety and security features has propelled the market growth. Installing these systems in a vehicle provides several benefits, such as the low probability of electrical shortage, enhanced performance, and improved fuel efficiency.

The rapid growth of the automobile industry worldwide due to several technologically advanced features implemented in vehicles is one of the major factors driving the automotive wiring harness market growth. In line with this, increasing electrification of vehicles, expanding demand and usage of hybrid and electric cars, and the growing emphasis on safety solutions are expected to boost the market over the forecast period.

Moreover, the utilization of reliable and cost-effective optical fibers along with the increasing demand for Advanced Driver Assistance Systems (ADAS) in automobiles is anticipated to drive the market in the coming years. In addition, many product innovations, for example, the development of aluminum harnesses, are acting as another market growth factor. Also, wiring harnesses are used for securing safety sensors, such as automated control systems and blind-spot detection. This helps to improve vehicle performance, which offers numerous opportunities for market expansion over the forecast period.

Halt in Production Lines and Disruption in the Supply Chain to Slow Down Market Growth Amidst COVID-19 Pandemic

The COVID-19 pandemic has impacted nearly every industry globally, and auto part and vehicle manufacturing industries are no exception. In 2020, the COVID-19 pandemic immensely impacted the integrated automotive industry worldwide. In 2020, the halt in production lines of many OEMs and disruption in the supply chain had indirectly affected the market. On the other hand, businesses have to restructure their strategies according to the changing automotive wiring harness supplies. However, the market is likely to bounce back after the pandemic. With the gradual removal of lockdowns in various nations, the demand for vehicles has slightly increased, which is predicted to propel the market in the coming years.


Asia Pacific Automotive Wiring Harness Market Size

Surge in Electric Vehicle (EV) Sales Expected to Drive Market Growth

In 2020, global electric cars sales increased by 41% to about 3 million from the previous year. In 2020, Europeans overtook China as the world's largest buyer of electric vehicles. Europe and China sold about 1.3 million electric cars, four times the number sold in the U.S. Moreover, the EV market has shown substantial growth rates in current years.

Further, in 2020, EV sales will be increased by double digits in several European countries despite the economic crash reflecting two policy measures. Carbon dioxide (CO2) emissions standards in the European Union (EU) play an important role in stimulating electric car sales. The growth in EV numbers is still majorly driven by the government policy environment. The leading countries in the EV market, such as the Netherlands, China, Norway, the U.S., Japan, Germany, Sweden, the U.K., Canada, and France, have a range of policies to encourage the acceptance of electric vehicles. As more EVs come on the road, the market is also anticipated to witness growth as automotive wiring harness is utilized in EVs than conventional fossil fuel-based vehicles.


Increasing Trend of Integrated Advanced Features in Vehicles that Propels Market Growth

Today’s cars are advanced with a large number of electronic integrations. By 2022, about 125 million vehicles are expected to be equipped with 5G connections that will hit the roads. Further, the head-up-display units, infotainment systems, and dashboards in vehicles require many electronic and electric components. As these electronic equipment are becoming a standard accessory, car manufacturers and consumers have pushed the electronic component suppliers for more integrations and innovations. Today’s consumers demand more intuitive technology, and they want an in-vehicle experience that allows them to stay connected, entertained, and comfortable. Therefore, car manufacturers look for best-in-class features and technology. These significant factors play an essential role in driving the global market.

Rising Automobile Production to Propel Market Growth

Increasing automotive production globally due to improving economies, increasing purchasing power, and improving lifestyles drive the overall demand for automobiles production. Presently, the Asia Pacific region accounts for the highest volume of automotive output due to the greater need for automobiles, especially in China and India. In addition, increasing financial and regulatory initiatives by governments boost the prospects in this market.


Corrosive Nature of Wiring Harness Hurdle to Hinder Growth

The issues of reliability and durability associated with the incorporation of wiring harnesses in EVs are projected to hinder the market growth. Further, the corrosive nature of the automotive wiring harness makes it challenging to incorporate into EVs. These factors, in turn, are estimated to restrain in the coming years. Additionally, the manufacturers must invest comprehensively in the research and development of advanced wiring harnesses, which may likely limit the market growth over the forecast period.
