Paul Marshall is the President and visionary leader behind Excel Connection Inc., a premier manufacturer of custom wire harnesses, cable assemblies, and electro-mechanical assemblies. With nearly 40 years of hands-on experience in the electrical and electronic manufacturing industry, Paul has spent his career building solutions that power critical infrastructure, heavy machinery, medical devices, and industrial automation worldwide.



Under his leadership, Excel Connection has grown from a specialized local supplier into an ISO 9001:2015 certified industry powerhouse known for precision engineering, rigorous quality control, and an unrelenting commitment to customer satisfaction. Paul’s deep technical expertise and strategic vision have positioned the company as a trusted partner for original equipment manufacturers (OEMs) across North America.

Decades of Technical Expertise and Leadership

Paul’s journey in the custom cable and wire harness manufacturing sector began four decades ago. Starting with a foundational understanding of electrical engineering principles and assembly operations, he quickly identified a growing gap in the industrial supply chain: companies didn't just need cable suppliers—they needed collaborative partners capable of solving complex engineering challenges, streamlining build times, and eliminating design flaws prior to production.

Throughout his career, Paul has spearheaded initiatives across every phase of the manufacturing lifecycle. His expertise spans automated wire processing, complex multi-conductor cabling, overmolding, prototype development, and inventory management strategies like Kanban and Just-In-Time (JIT) delivery. By keeping Excel Connection at the cutting edge of manufacturing technology, Paul has ensured that the company continuously adapts to evolving industry standards, higher safety regulations, and increasingly complex client specifications.

Driving Quality, Innovation, and Reliability

At the core of Paul’s business philosophy is a simple principle: quality is non-negotiable. Industrial assemblies often operate in harsh environments where equipment failure is not an option. Whether supplying heavy-duty wiring harnesses for construction equipment or intricate cable assemblies for sensitive diagnostic medical instruments, Paul has instilled a culture of zero-defect manufacturing at Excel Connection.

Under Paul’s direction, Excel Connection maintains full compliance with UL and CSA standards and utilizes state-of-the-art automated crimping, cutting, and testing machinery. His commitment to continuous process improvement has enabled the business to minimize turnaround times without sacrificing the meticulous attention to detail that custom electrical assemblies require.

Beyond technical precision, Paul prioritizes supply chain resilience. By cultivating strong, long-term relationships with component suppliers and maintaining extensive raw material inventories, he has guided clients through global supply chain disruptions, ensuring their assembly lines remain operational and on schedule.

Thought Leadership and Collaborative Partnerships

As President, Paul Marshall remains directly engaged with Excel Connection’s client base. He believes that true manufacturing partnerships are rooted in open communication and technical collaboration. He works closely with engineering teams, supply chain managers, and procurement officers to help optimize their designs for manufacturability (DFM), reducing production costs while enhancing product longevity and performance.

Paul regularly shares industry insights on manufacturing best practices, cable harness design, supply chain optimization, and the future of industrial automation. His long-standing presence in the industry has made him a trusted authority for OEMs seeking to modernize their electrical architecture and scale their production capabilities.
