Zuken Releases Harness Builder for E3.series 2026 for Wire Harness Manufacturing

WESTFORD, Mass., and MUNICH, Germany—March 10, 2026—Zuken USA announced the release of Harness Builder 2026, the latest version of its wire harness manufacturing software. Designed for OEMs and harness shops alike, this release adds updates for estimating and quoting, bill of materials (BOM) management, build documentation, and shop-floor connected manufacturing.

Estimating and quoting with current BOM inputs

Harness Builder 2026 links the Cost Estimator to TrustedParts.com to access current component pricing and availability information. Users can automatically retrieve live cost and availability data and selected component details from the harness design BOM to support estimates and quoting workflows.

“Harness teams shouldn’t have to chase pricing and availability across multiple sources just to build an estimate. Harness Builder 2026 brings current BOM inputs into the quoting workflow through TrustedParts.com integration, helping teams spend less time on data gathering and more time delivering quotes.”
— Paul Harvell, vice president of engineering, Zuken USA

DS-E3 integration for production BOM management

Harness Builder now integrates with DS-E3, Zuken’s electrical data management solution, to store and manage production BOM data. Teams can incorporate Harness Builder BOMs into DS-E3 document generation workflows and use structure-based filtering and where-used views to support traceability across the project.

Documentation updates for manufacturing packages

Harness Builder 2026 adds Connection Line Resize to adjust the thickness of connection lines to match the segment’s bundle diameter, providing clear visual guidance for technicians laying out wire on printed documentation.

The Wire Run List can now display wire seal attributes beyond the part number, allowing manufacturers to include additional information, such as supplier details, directly in production reports.

Connected manufacturing and equipment support

A new 4Wire CAO export supports MES connectivity with Komax, for data exchange between design output and wire processing equipment. The release also expands harness manufacturing automation and test equipment support, including:

• Support for MK and Weetech testers
• Updated Cirris and Dynalab tester integrations
• CMS interface for KM Digitech wire processing systems

“The 4Wire CAO export is a practical step toward connected manufacturing—supporting data exchange between design outputs, Komax MES and downstream wire processing. Combined with expanded tester integrations and KM Digitech support, this release gives manufacturers more options to align documentation, automation and test processes.”
— Bob Potock, vice president of marketing, Zuken USA

Weight planning within a system design

Sub-project Weight Estimate provides harness-level weight rollups within a complete system design package, helping engineering teams compare estimates against weight targets and share precise expectations with manufacturing.

Key Capabilities

• com linkage in Cost Estimator for current pricing and availability inputs.
• DS-E3 integration to store and manage production BOM data and support document generation workflows
• Connection Line Resize for clearer formboard documentation
• 4Wire CAO to support Komax MES connectivity
• Expanded tester/equipment support (MK, Weetech, Cirris, Dynalab; KM Digitech CMS)
• Sub-project Weight Estimate for harness-level rollups and target comparisons

Availability

Harness Builder for E3.series 2026 is available in North America and Europe.
