30Pin Natural Male Wire Harness Connector with Terminals – Automotive Connector with TPA for Select Toyota Models

The TS30101-30P-11-4 is a 30-pin natural-colored male wire harness connector designed for reliable and secure automotive electrical connections. Featuring an integrated TPA (Terminal Position Assurance) system, this connector ensures maximum terminal retention and prevents contact backout caused by vibration, thermal cycling, or mechanical stress—common challenges in automotive environments. Engineered for select Toyota vehicles, this male connector serves as a critical component in factory-matched audio and control harness assemblies, enabling clean, non-invasive upgrades when replacing original head units with aftermarket stereos.

Ideal for use in car audio retrofit kits, marine applications, UTVs, and off-road vehicles, this connector supports full signal transmission across speaker lines, power circuits, grounding paths, and accessory control signals. The natural (beige/off-white) housing blends seamlessly with OEM wiring looms, maintaining a factory-original appearance while ensuring professional-grade reliability. Whether used in DIY installations or commercial harness manufacturing, the TS30101-30P-11-4 delivers consistent performance and long-term durability.

Key Product Specifications

Enhanced Reliability with Built-In TPA Design

Unlike standard connectors, the TS30101-30P-11-4 includes a Terminal Position Assurance (TPA) mechanism that locks terminals securely in place after crimping and insertion. This secondary locking feature prevents accidental terminal displacement due to road vibration or thermal expansion, significantly reducing the risk of intermittent connections or signal loss. The TPA also enhances assembly accuracy by providing tactile feedback during installation, ensuring each terminal is fully seated before final mating.

We offer two versions of the TS30101-30P series: one with TPA and one without. The TPA-equipped models feature slight structural differences on the connector side to accommodate the locking mechanism, making them ideal for high-vibration environments such as off-road vehicles, marine applications, and performance cars. For applications demanding maximum reliability, the TPA version is the preferred choice.

Factory-Compatible Male Connector for Toyota audio systems

This male connector is specifically designed for compatibility with select Toyota models that use a 30-pin audio harness interface. When paired with its mating female housing TS30101-30P-21-4, it forms a plug-and-play solution for connecting aftermarket stereos to factory wiring. The natural-colored housing matches the original equipment appearance, supporting clean, professional installations without visible modifications.
