Heavy Equipment Wire and Cable Harness Assembly Solutions

A Proven, Disciplined Heavy Equipment Electronics Contract Manufacturing Partner

Built for Strength. Trusted to Deliver.

In heavy equipment electronics manufacturing, there’s no room for failure. You need components that work as hard as the machines they power. That’s where we come in.

At ETI/ACH, we don’t just build wire harness assemblies, printed circuit board assemblies, and electro-mechanical box builds—we build reliability. Our components power the toughest machinery out there, from bridge-building behemoths to the rigs that harvest potatoes in Idaho. A bad harness isn’t just a nuisance—it’s costly downtime, lost productivity, and a machine that’s dead in the dirt. When every minute counts, you need a partner that delivers flawless execution, every time.

For over 40 years, we’ve been the disciplined, no-BS manufacturing partner that keeps production lines moving and equipment working in the field.

Complex Harnesses Require Specialized Expertise

Our customers can count on the integrity of each and every wire harness assembly. The harnesses used in heavy equipment can be very large and elaborate, requiring a well-trained team utilizing strict process controls and the ability to read and understand complex assembly prints. These harnesses can also be extremely heavy, requiring alternate handling and packaging methods. Most involve several disciplines, such as braiding, ultrasonic welding/butt splicing, custom wire marking/labeling, pull testing and continuity testing.
