SESCO began in 1983 by founder David Souders as a wiring harness manufacturer in a small outbuilding behind his home. Over the years SESCO grew into an electrical contract manufacturer by supplying custom electrical assemblies and providing design and engineering services to OEMs throughout the United States. Today, SESCO has two manufacturing facilities in Pennsylvania.
