Our Products

Sumitomo is responding to advances in vehicle electronics by developing and enhancing harness components, electronic control units and automating the assembly process. Our entire organization is committed to using advanced technologies, such as fiber optics and multiplexing, in pursuit of comprehensive solutions to the challenges created by the revolution in automotive and truck electronics.

Electrical distribution systems are unique to each make and model, resulting in a virtually unlimited range of configurations that Sumitomo Electric Wiring Systems builds for our customers. While many elements of the manufacturing process are automated, the finished product is still very much "man-made." Keen minds manage the sequence of steps. Knowing eyes and skilled hands quickly respond to engineering changes. Experienced associates rapidly deliver critical prototypes.
