About ACI

Your trusted partner for custom engineering and agile service.

Our Story

From our humble beginnings in a 12′ x 12′ space back in 1997, ACI has grown into a leading name in custom-engineered cable and harnessing solutions. Founded by Kevin O’Sullivan and Tim Kucera, the company began with a bold vision and a commitment to hard work and innovation.

As ACI has grown over the years, we’ve continued investing in our state-of-the-art equipment and facilities, including our recent expansion to Mexico. Along with enabling us to offer a higher volume of complex and custom engineered solutions, we’ve also established a strong molding presence in the industry. At the same time, as a company that is still operated by its founders, we’ve remained true to the same commitment to engineering and service excellence that has driven us since day one.

Moving forward, ACI is well positioned to continue growing and evolving alongside our customers. By focusing on engineering excellence, multi-tier sourcing, and highly adaptable service, we aim to solidify our reputation as go-to partners in the industry.

Why Customers Choose ACI

Why do customers trust ACI? We believe it comes down to a few key strengths.

Engineering Excellence

ACI does much more than manufacture wire harnesses. When you have a complex challenge, think of us as your co-engineering partner that can deliver precision solutions quickly and accurately. Put simply, we are your partner for Engineering Quality Connections.

Multi-Tier Sourcing Capabilities

You need a supplier that can deliver reliably cost-efficiently for every request. That’s why we offer multiple sourcing solutions – from our Mexican plant’s high-volume production to our Joliet facility’s fast turnarounds for smaller orders, and our vetted overseas partners.

Flexibility and Responsiveness

We understand you have no shortage of challenges to manage. Between our flexible, responsive service and our ability to get the job done right the first time, we go the extra mile to make doing business with us easy.
