InSource Technologies, Inc., a trusted U.S. custom wiring harness manufacturer, is excited to announce the launch of InSource Wiring — a new 2nd business unit dedicated exclusively to custom wiring harness assembly and design.
This strategic expansion allows InSource to meet growing customer demand for high-quality wiring harness solutions while maintaining the precision, reliability, and responsiveness the company is known for. As a leading custom wiring harness manufacturer in the U.S., Wiring supports OEMs across agriculture, fire and rescue, forestry, and industrial equipment sectors.
“As a business unit grows, it becomes more challenging to maintain our high standards,” said Larry Manz, Director of Sales & Marketing. “Creating Wiring as a distinct unit ensures that every wiring harness assembly meets our rigorous standards while allowing us to serve customers faster and more effectively.”
Industry Recognition
InSource’s growth and customer-focused strategy were recently highlighted in Wiring Harness News (WHN), which interviewed key team members about the launch of the 2nd business unit for wiring harness manufacturing. WHN also featured a profile on InSource in 2022, underscoring the company’s reputation for operational excellence and innovation.
Expanding Capacity and Opportunities
Until recently, InSource had reached a point where it was declining new wiring harness requests, due to high demand and limited capacity. The creation of Wiring has allowed the company to reopen quote requests, giving customers the chance to access high-quality, U.S.-made wiring harness solutions once again.
The team is especially excited about opportunities that integrate our other business units, such as SMT and controls, for bare board manufacturing, full assembly builds and turnkey products. This integrated approach allows InSource to provide complete solutions to customers looking for end-to-end manufacturing support, from circuit boards to fully assembled harness systems.
By expanding capacity, customers now benefit from shorter lead times, faster project turnaround, and greater flexibility in design and production. This means InSource can now take on more complex, high-mix projects while maintaining the same exceptional quality standards for which the company is known.
Leadership, Innovation, and Culture
It’s been fun to see how two different leaders manage similar business units. While both Harness and Wiring operate under the same operational philosophy, there’s been a healthy amount of friendly competition, driving innovation and operational improvements across the organization.
New engineers have also joined Wiring, bringing fresh perspectives and creative solutions. One engineer, in particular, developed a machine that improves harness building, allowing the team to assemble components with higher precision, faster production speed, and better overall quality. Innovations like this highlight InSource’s commitment to continuous improvement and advanced manufacturing techniques, ensuring that customers always receive the most reliable and efficient wiring harness assemblies.

Meeting Industry Demand
The wiring harness industry is growing rapidly due to reshoring trends, more complex systems, and increasing demand for short-run, high-mix production. InSource Wiring positions the company to respond to these trends, offering custom wiring harness assembly that is flexible, reliable, and made in the U.S.
“This is an exciting opportunity to strengthen InSource and better serve our valued customers,” said Larry Manz. “Every custom wiring harness we build supports performance, safety, and operational excellence.”
