Increasing construction activities are expected to drive the growth of the wire harness market going forward. Construction involves assembling various components to create structures based on detailed plans and designs. Wire harnesses are essential in construction projects because they provide organized, reliable, and efficient electrical connectivity across multiple applications. For example, in July 2024, the US Census Bureau, a US-based government agency, reported that the value of construction operations rose from $2.01 trillion in May 2023 to $2.14 trillion in May 2024. Therefore, the rise in construction activities is contributing to the growth of the wire harness market.

Major companies in the wire harness market are developing innovative solutions such as harness design and manufacturing software to improve production efficiency and precision. Harness design and manufacturing software consists of specialized digital tools that help engineers design, develop, and produce wire harnesses more effectively. For instance, in May 2023, Zuken Inc., a Japan-based software and consulting services company, released Harness Builder 2023 for the E3.series. This updated software includes a modern user interface for better usability, an auto-dimensioning tool to simplify segment measurement across harnesses, and improved handling of twisted pairs to reduce material waste. It also offers enhanced splice documentation, cost and weight estimation features for accurate quoting, and options for adding customizable watermarks to design drawings.

In December 2023, Second Flight Capital, a US-based investment firm that supports business owners in transitioning their companies while preserving their legacy, acquired Qualtronics LLC for an undisclosed amount. The acquisition aims to strengthen Second Flight Capital’s presence in custom wire harness manufacturing by leveraging Qualtronics’ strong reputation and commitment to sustainable growth, aligning with the firm’s mission of supporting long-term business and community success. Qualtronics LLC is a US-based provider of contract manufacturing, design, and prototyping services for custom wire harnesses and control panels.
