In line with these advancements, the introduction of autonomous and semi-autonomous vehicles, which have a high dependency on components such as low-latency communication devices, sensors, cameras, and radar, will increase the demand for automotive wiring harnesses within the automotive manufacturing industry, thereby offering numerous growth opportunities to the automotive wiring harness marketers. Moreover, the increasing use of optical fiber for producing wiring harnesses is expected to create new opportunities for market players.

The rising consensus pertaining to security and safety while driving is fueling the demand for driver-assisting technologies such as adaptive cruise control, blind spot detection, adaptive front light, and lane departure warning system. Additionally, vehicle manufacturers are obliged to comply with stringent safety norms introduced by authorities worldwide and are expected to support market growth. For instance, On July 6th, 2022, European Union introduced new safety measures to reduce commute-related injuries and fatalities by applying general safety regulations.

The regulation sets the legal framework for the EU's approval of fully driverless and automated vehicles and introduces advanced driver assistance technologies for passenger and commercial vehicles. The deployment of cables or wire harnesses is anticipated to gain traction owing to its incorporation into multimedia and security systems. To enhance the driving experience, features including ambient lighting systems, cooled cup holders, voice recognition systems, heated steering wheels and seats, infotainment, and power steering functions have gained prominence. A wiring harness is necessary for the data, signal, and power transfer in electronic equipment which enables these functions. Wiring harness bundles are put in automobiles with these circuits to ensure that various features operate without interruption. Thus, the market is experiencing growth due to its application in the automotive industry.

The demand for automotive wiring harnesses is increasing owing to the connected car ecosystem, new laws, electrification, growing preference for 48V high voltage capacity, and an increase in comfort and safety features in automobiles. Throttle control, steering, and braking are essential vehicle activities that the electronic control unit (ECU) aids. Throughout the sensors, actuators, and ECU, the wiring harness facilitates the transmission of signals, power, and data. The development of electronic and electrical features in vehicles further exacerbates the need for wiring harnesses. Governments in North America, Europe, and Asia-Pacific are advocating for an increase in the integration of ADAS systems, telematics, and low-emission engines such as China VI, Euro VI, and BSIII to BSIV electronics engines. These engines increase the application sensors radar, telematics, and communication devices. Thus, the growing need for connectivity and data transmission in automobiles is anticipated to propel automotive wiring harness market growth within the forecast period.

The increasing traction of electric vehicles worldwide is also generating demand for lighter-weighing harnesses. Integrating an electric power train into a vehicle significantly increases the vehicle’s weight; furthermore, the amount of wiring harness integrated into vehicles also adds to the vehicle’s weight. These underlying factors impact vehicle performance and efficiency. However, such factors fuel the demand for aluminum-based wiring harnesses that help reduce bundle diameter, weight, and cost as compared to copper-based wiring harnesses. Additionally, the strong demand for displays, cameras, and other infotainment devices, has led to the development of technologies for transmitting camera and video signals over a single specialty cable along with lowering the weight and expense of wiring harnesses. OEMs favor optical fiber and aluminum for lightweight, efficient harnesses. Fiber optic cable is more resistant to environmental variables than copper wire. To transmit high-speed data, firms are switching to optic fiber wiring harnesses

Exposure to heat, cold, vibrations, and corrosion are major restraints affecting the growth of the automotive wiring harness market. Rapid temperature changes, such as those from extreme heat to extreme cold, and other abrupt changes in temperature might cause the wiring harness to bend occasionally. These factors may cause the wiring harness lifespan to shorten. The wiring harness-powered sensor system is impacted by corrosion. A sensor can interpret a current and voltage flow deterioration brought on by excessive corrosion as a system problem. The issue may cause safety features like airbags and anti-lock brakes to stop working. Additionally, this results in a number of issues like wire deterioration and fire dangers. Furthermore, the fluctuating prices of metals such as copper and aluminum also affect the supply chain and the automotive wiring harness prices, thus affecting the market growth.
