What Are Wire Harnesses Used For?
A wire harness is a group of wires bundled together in a precise configuration to help route, organize and protect electrical wiring. Wire harness assemblies make repairs, maintenance, installation and production easier while helping reduce clutter inside equipment, vehicles and electromechanical devices.
High-quality wire harnesses are used across many industries, including:
Custom Wire Industries manufactures wire and cable assemblies for each client’s design, performance requirements and project scope.
Automotive Wire Harnesses
Custom Wire Industries manufactures automotive wire harnesses for restoration projects, custom builds, specialty vehicles and production applications. Whether you need a wiring solution for a classic vehicle, a custom car build or a specialized automotive electrical system, our team can fabricate a harness built for fit, durability and dependable performance.
Automotive wire harnesses offer major advantages over loose wires and cables. Vehicles contain wiring throughout the cabin, engine compartment, lighting systems and controls. A custom wire harness organizes those cables into a protected bundle, helping improve space usage, simplify installation and reduce wear caused by vibration, heat and daily use.
