Vietnam Automotive Wiring Harness Market Trends and Drivers:
The main growth driver of automotive wiring harness in Vietnam is the automotive industry’s transition to support the rapid localization of electric and hybrid vehicle production. It is not a simple upgrade, but a redesign of basic modules and systems that will require a new generation of automotive wiring harnesses. Unlike the harnesses in an internal combustion engine, electric vehicle harnesses must be able to handle much higher voltages, mostly above 800 volt for fast charging to be supported, and therefore require cables with a higher thermal resistance and shielding. The harnesses connect the powertrain, battery management system and thermal system to the vehicle, and as such must be manufactured to the highest standards. Some of the world’s largest harness makers with a production presence in Vietnam are investing tens of millions of dollars to build dedicated lines for high-voltage harnesses. While serving local EV start-ups and global OEMs opening their assembly lines in Vietnam, the new production lines of harness makers will support the establishment of a full and technologically advanced EV supply chain ecosystem in the country. This ecosystem is increasingly self-sufficient and competitive on the global supply chain, therefore driving up the value per car despite fluctuations in EVI total vehicle volumes.
Also driving the supply chain localization and vertical integration are recent global shocks and industrial policies by the government, all of which have led to domestic supply chain upgrades. Increasing domestic backward integration is one means that large harness manufacturers use to reduce the costs and risks of importing raw materials into Vietnam. This can come as we increasingly rely upon or invest in local manufacturers. They make key harness inputs such as copper wire, specialized polymer insulation, connectors, terminals, and end lugs. This consolidation represents an attractive opportunity for multinational companies. It is supported by domestic manufacturing initiatives as they look to ramp up their presence in the local market. In addition, this consolidation enables us to improve manufacturing efficiency, shorten lead times and become more cost-competitive in our ability to manufacture wiring harnesses in Vietnam for use internationally. Vietnam will be more than simply a more cost competitive assembly location as we move to being able to produce a full, quality wiring harness with a much higher domestic value-add. This investment also acts as a means to establish Vietnam as an attractive automotive investment destination that is insulated from outside supply and trade considerations.
The third major trend is the increased use of ADAS, which is greatly increasing the complexity, data bandwidth, and value of the modern automotive wiring harness. Consumer interest in safety systems and autonomous driving features is increasing greatly, and the number of sensors, cameras, radar, and LiDAR being installed in vehicles is rapidly growing. These features require data with high bandwidth and thus the cable needs to be reengineered to use coaxial and high-speed differential twisted pairs which can carry large amounts of data very efficiently with very little signal loss and very little electromagnetic interference. The harness, which was originally simply used to distribute electrical power and basic signals, has now become the vehicle’s central nervous system, carrying data for real-time decisions. This requires greater collaborative working between harness designers and vehicle engineers from the very start of the development cycle to ensure the optimal routing, shielding and connector quality. For Vietnam-based manufacturers, this is both a threat, and an opportunity. They must invest in training their staff and acquiring high-technology test equipment, but in return they will be able to capture a higher value share of the vehicle by producing the complex data-rich harness assemblies that are critical to the next generation of clever vehicles.
