Connector Library - 1,350+ Connectors Ready to Use Out of the Box

Today we're shipping the Connector Library - a central place to create and manage reusable connectors across all of your wiring harnesses. Powered by Corsa Technic.

Building harnesses in a spreadsheet or other wiring software means recreating connectors from scratch for every project - finding part numbers, images, manually entering cavity data, formatting and repeating the same work each time. The Connector Library solves that.

Preloaded with over 1,350 automotive connectors from the Corsa Technic library. Many of the common connectors are covered, but you can also add your own connectors and mark them as personal or share them across your team.

Why it matters for wiring harness design

Other electrical harness design software has offered connector libraries for years, but those tools often require you to build your own connector library from scratch.

Whether you're building a single custom harness or building harnesses every day, a shared library keeps everything consistent and cuts setup time considerably. Update a design once and it's reflected everywhere it's used.

Over 1,350 connectors ready to use

We've pre-loaded the library with over 1,350 connector designs covering common automotive connectors. You can also customise library connectors with your own images and cavity names.

Full documentation is available in the Connector Library guide.
