Product Details

Product Specifications & Material	Functional Advantages & Stability	Strategic Value for Assembly
Integrated Secondary Locking Design	The TPA cannot be closed unless all terminals are perfectly seated in the cavity.	Eliminates Assembly Errors: Acts as a mechanical “poka-yoke” (error-proofing) during harness production, ensuring 100% terminal engagement.
Vibration-Resistant Black Resin	Made from automotive-grade thermoplastic that maintains its tension under extreme engine heat and road vibration.	Enhanced Connection Security: Prevents terminals from backing out due to mechanical stress, significantly reducing warranty claims related to loose connections.
Optimized for Convoluted Conduits	Specifically engineered to fit within or alongside convoluted tubing interfaces common in engine bays.	Simplified Harness Integration: Allows for seamless wire protection management without compromising the connector’s locking integrity.
Lightweight 2-Position Profile	Adds minimal weight (0.088 oz) while providing robust physical reinforcement to the circuit.	System Weight Efficiency: Provides maximum reliability for sensors and small actuators without increasing the overall footprint of the wiring system.

Q1: What is the primary purpose of the Aptiv 15327747 TPA?

A: The 15327747 TPA (Terminal Position Assurance) acts as a secondary lock for automotive connectors. Its main job is to ensure that the electrical terminals are fully inserted into the housing. If a terminal is not correctly seated, the TPA will not click into place, alerting the technician to fix the connection immediately.

Q2: Can the 15327747 lock be reused if I need to repin the connector?

A: Yes, in most cases, the 15327747 can be carefully pried open using a specialized terminal removal tool or a small flathead screwdriver. This allows for harness repairs or terminal replacements without needing to replace the entire locking clip, provided the plastic tabs are not damaged.

Q3: Why is this specific model recommended for convoluted conduit applications?

A: This model is designed with a profile that accounts for the clearance and attachment points required when a connector is integrated with convoluted tubing (conduit). It ensures that the wire protection does not interfere with the primary or secondary locking mechanisms of the harness.
