30Pin 2mm 1.8mm Natural Wire Harness Connector with Terminals – Automotive Connector with TPA for Select Toyota Models

The TS30101-30P-21-4 is a high-precision 30-pin natural-colored wire harness connector engineered for automotive audio and control signal transmission. Designed with a 2.0mm to 1.8mm terminal pitch compatibility, this female connector ensures secure and stable Electrical Contact in factory-matched wiring systems. As the mating counterpart to the male plug TS30101-30P-11-4, it plays a crucial role in non-invasive stereo upgrades for select Toyota vehicles, allowing seamless integration of aftermarket head units without altering original wiring. The connector features an optional TPA (Terminal Position Assurance) mechanism, enhancing terminal retention and preventing backout in high-vibration environments such as cars, yachts, and UTVs.

Manufactured with either PBT+GF15% or PA66+GF30% insulation material, the TS30101-30P-21-4 delivers excellent resistance to heat, impact, and chemical exposure. Its natural beige housing blends with OEM harness aesthetics, supporting clean, professional installations. Whether used in DIY audio kits or commercial harness production, this connector provides reliable performance and long-term durability under demanding automotive conditions.

Detailed Product Parameters

2.0mm/1.8mm Terminal Pitch Compatibility for Broad Interchangeability

The TS30101-30P-21-4 supports both 2.0mm and 1.8mm terminal sizes, offering flexibility in terminal selection and compatibility with various crimp tools and wire gauges. This dual-pitch design ensures reliable signal transmission across speaker outputs, power feeds, ground circuits, and accessory triggers in automotive audio systems. The precision-molded cavities guide terminals into correct alignment, minimizing insertion force and reducing the risk of damage during assembly.

This female connector is available in two structural variants: one equipped with a TPA (Terminal Position Assurance) clip and one without. The TPA version includes a secondary locking mechanism that secures terminals after insertion, preventing vibration-induced displacement—a critical feature for marine, off-road, and performance vehicle applications. The presence of TPA results in slight design differences on the connector side, ensuring proper mechanical engagement and long-term reliability.

Factory-Style Integration for Select Toyota Vehicles

Engineered as a direct-fit solution for select Toyota models, the TS30101-30P-21-4 enables installers to create plug-and-play harness adapters that preserve the original wiring loom. When paired with its male counterpart TS30101-30P-11-4, it forms a complete wire-to-wire connection system ideal for stereo upgrades, navigation installations, and audio system retrofits. The natural housing color matches factory harnesses, maintaining a clean, OEM-like appearance and simplifying identification during installation.
