The list of automotive amenities being offered continues to grow... and Sumitomo Electric Wiring Systems continues to respond with advanced product design and manufacturing solutions that our global customers demand. Working as an extension of our customers' design and engineering teams, we collaboratively engineer electrical and electronics systems that push the envelope of automotive solutions.

Sumitomo Electric Wiring Systems is a single-point system integrator. That means we design and deliver "total" electrical and electronics systems - not just components and parts. First, we listen to our customers. We take the time to understand their vision, requirements and specifications - cost, size, performance, quality and time to market. Then, we leverage our research and engineering know-how to develop solutions that are not only innovative, but also affordable. Most importantly, we draw upon systems expertise to streamline the entire product development process, from concept to manufacturing and delivery.
