30 Way Female White Automotive Connector with TPA – TS30358-30P-21-3 (Compatible with 33268473)

The TS30358-30P-21-3 is a high-performance 30-pin female automotive connector designed for use in factory-installed audio systems and control harnesses across a wide range of vehicles. As the female housing counterpart to the male plug TS30358-30P-11-3, this white-colored connector features a built-in Terminal Position Assurance (TPA) system that secures each terminal in place, ensuring reliable Electrical Contact and preventing backout due to vibration or mechanical stress. It is engineered as a direct solution for applications requiring compatibility with OEM part number 33268473, making it ideal for vehicle stereo upgrades, harness repairs, and custom integration projects in cars, marine vessels, UTVs, and specialty vehicles.

Designed for seamless integration into existing wiring architectures, this connector supports plug-and-play installations without the need for cutting or splicing. Its precise molding and terminal alignment ensure consistent mating performance, preserving signal integrity and reducing the risk of intermittent faults in demanding mobile environments.

Technical Specifications Overview

Engineered for Secure and Vibration-Resistant Connections

The TS30358-30P-21-3 female connector is specifically designed to accept the male plug TS30358-30P-11-3, forming a fully sealed and mechanically stable junction. The integrated TPA (Terminal Position Assurance) system plays a critical role in maintaining terminal integrity by locking each contact in its designated cavity, eliminating the risk of terminal displacement during vehicle operation. This feature is especially valuable in off-road, marine, and high-performance applications where constant vibration can compromise standard connectors.

The white housing provides easy visual identification during wiring, reducing installation errors and streamlining service procedures. Its design supports quick and reliable mating, with clear tactile feedback confirming full engagement.

High-Grade Materials for Long-Term Reliability

Constructed from either PBT+GF15% or PA66+GF30%, the connector body delivers excellent thermal resistance, mechanical strength, and dimensional stability. These reinforced thermoplastics ensure the housing remains intact and functional even under prolonged exposure to elevated temperatures and harsh environmental conditions. The internal Terminals are made from high-conductivity copper alloy, brass, or phosphor bronze, offering superior electrical performance and resistance to oxidation, ensuring consistent signal transmission for audio, power, and control circuits.

With the rising usage of wire harnesses, thanks to their efficiencies and plethora of advantages, the demand for a variety of different harnesses is also on the rise.

The sole purpose of a connector type wire harness is to transmit electrical signals from the wire harness to the power source. Connectors comprise of different plugs and jacks, the design being based on the function and performance required. There are essentially two main types of wire harness connectors – male and female, which serve to provide the necessary junctions between the many different elements of the wire harness.This aptiv 30way connector with TPA are made by ourself in three color, Grey, Black, White. We have the female one, male one and the mated terminals.
