Automotive Harness Trends: More Terminals per Wire

Harness designs continue to add more terminations per wire as vehicles carry more sensors, displays and control modules. Each added branch increases the number of crimps, seals and connectors that must be processed and inspected within the same build window.

That shift changes what equipment needs to deliver. Lines are expected to handle a wider mix of wire sizes, support more terminals per cycle, and keep traceability for every termination without slowing the overall rate.

Where the pressure shows up

• More crimp points per harness to apply and verify
• Wider mix of wire and terminal types on one line
• Growing demand for inline inspection and data records
• Consistent quality across higher termination counts

For harness builders, the practical response is flexible processing equipment and clear inspection data, so added complexity does not translate into more manual rework.
