Delphi Metri-Pack 150 Series Secondary Lock for use with Automotive Connectors

The Delphi 12066304 is a secondary lock (Terminal Position Assurance – TPA) designed for use with Metri‑Pack 150 Series automotive connectors. The medium-grey lock is moulded from PA66‑HS‑IM nylon and engineered for easy insertion into the connector housing, adding an extra layer of reliability to wire‑harness assemblies. The tooling for insertion is minimal, enabling efficient assembly and servicing in both production and aftermarket scenarios.

What Benefits Does It Offer to Users?

• Secondary lock feature provides extra retention for Metri‑Pack 150 terminals.
• Compatible with 8‑way connector assemblies in Metri‑Pack 150 series.
• Medium-grey PA66‑HS‑IM nylon construction offers durability and chemical resistance.
• Fits remanufactured and original equipment harness applications for automotive use.
• Supports SAE‑standard wire crimps with Metri‑Pack 150 Series to maintain locking integrity.
• Compact design simplifies integration into multi‑pin automotive connectors in a limited space.

Engineered for Harness Reliability

The 12066304 secondary lock enhances the retention performance of Metri‑Pack 150 Series connectors by locking the terminals in place, limiting terminal movement or partial unseating under vibration or thermal cycling. Its robust nylon composition resists oils, fuels, and high temperatures common in under‑hood automotive applications.

Application Potential of the Delphi Secondary Lock for Automotive Connectors

• Automotive wiring harnesses.
• After‑market connector repair kits and refurbishment of Metri‑Pack 150 assemblies.
• Industrial equipment and mobile machinery.
• EV/HEV control modules, sensor modules, and ECU assemblies.
• Service after-sales or maintenance operations.
