Purple-Latch 6-Pin Female Connector for Delphi GT150 Systems

The distinctive purple locking tab on the TS30381-06P-21 makes it instantly recognizable and easy to identify during installation or maintenance—especially in complex wiring bundles. This visual cue, combined with its precise fit for the Aptiv GT150 series, allows technicians to quickly verify compatibility and ensure correct mating with the TS30381-06P-11 male housing. The latch mechanism provides a secure click-lock engagement, resisting accidental disconnection due to vibration or mechanical stress.

Engineered for Harsh Environments with Superior Sealing

Designed from the ground up for demanding applications, this connector features integrated seals that protect against water ingress, dust, and contaminants. Whether installed under the hood, near wheel wells, or on a marine vessel exposed to salt spray, the TS30381-06P-21 maintains a reliable connection even in wet or dirty conditions. Its sealed design meets IP-level protection expectations, making it ideal for use in outdoor vehicles like UTVs, boats, and heavy-duty trucks.

Direct Fit Replacement for 15355297 – No Rewiring Needed

As a plug-and-play solution for the 15355297 connector, the TS30381-06P-21 eliminates the need for splicing, soldering, or modifying factory harnesses. It matches the original in pin configuration, polarity, and physical dimensions, allowing for fast, error-free replacement. This saves time and labor costs for repair shops and DIYers while restoring full functionality to aging or damaged audio and electronic control systems.

Durable Composite Housing Resists Heat, UV, and Chemical Exposure

The housing is constructed from either PBT+GF15% or PA66+GF30%, two high-strength thermoplastics known for their excellent thermal stability and resistance to cracking. These materials withstand extreme temperatures, UV radiation, and exposure to oils, fuels, and cleaning agents—ensuring the connector remains intact and functional over years of service, even in sun-drenched or engine-compartment installations.

Ideal for Automotive, Marine, and Recreational Vehicle Upgrades

This connector supports a wide range of uses:

• Replacing failed connectors in Delphi-equipped OEM audio systems

• Building custom waterproof harnesses for marine stereo installations

• Wiring lighting, sensors, or control modules in off-road and utility vehicles

• Upgrading factory head units with aftermarket stereos using adapter harnesses

• Repairing damaged connections in high-humidity or high-vibration zones

Its versatility and rugged design make it a go-to choice for professionals across multiple industries.

Premium Terminal Metals Ensure Stable Electrical Performance

Internal Terminals are crafted from copper alloy, brass, or phosphor bronze—materials selected for their superior conductivity, corrosion resistance, and mechanical resilience. These metals maintain consistent contact pressure over time, minimizing voltage drop and preventing intermittent signals that can disrupt audio quality or system operation.
