Cord Master Engineering produces made in the USA wiring harnesses.

North Adams Made In The USA Wiring Harnesses
We build all of our made in the USA wire harnesses at our facility in North Adams, MA. The North Adams location is what gives us HUBZone certification. Roughly 20 individuals are employed at this facility which is in one of the most economically disadvantaged towns in the Commonwealth of Massachusetts.
Our procurement department priority sources wire, molding compounds, connectors and other components we use to manufacture our products from US-based suppliers whenever possible.
