Mr. Charles E. Gillman gave us our start in 1955, on $10,000 of borrowed money!! We quickly developed a niche in manufacturing Wiring Harnesses and Cable Assemblies for Military Ground Combat and Tactical Vehicles, and have been the industry leader ever since. Additionally, we manufacture RF/Microwave Cable Assemblies which serve the Telecommunications and Aerospace Industries as well as diverse Military applications.

Initial business was the manufacture of wiring harnesses for the Diamond T Truck Company.

In 1970 the company moved to southern Arizona and established one of the first Maquiladora or “Twin Plant” operations with facilities on both the U.S. and Mexican sides of the border.
