66-Pin Blue Female Wire Harness Connector – TS30283-66P-21-1 with Lock for Toyota Automotive Audio and Control Systems

The TS30283-66P-21-1 is a high-performance blue female connector designed for use in Automotive Wire Harness applications, especially in Toyota vehicles requiring reliable 66-pin signal transmission. As the female mating component to the TS30283-66P-11-1 male housing, this connector ensures a secure, stable, and vibration-resistant connection in critical systems such as factory-installed audio units, infotainment modules, ECU interfaces, and dashboard control networks. Its integrated locking mechanism prevents accidental disengagement, making it ideal for use in dynamic environments including passenger cars, marine yachts, UTVs, and off-road vehicles.

Constructed from high-grade thermoplastic materials—PBT+GF15% or PA66+GF30%—this connector offers superior resistance to heat, impact, and chemical exposure. The blue housing provides clear visual identification, helping technicians and assemblers quickly distinguish it from other connectors in complex wiring looms, reducing installation errors and streamlining repair processes. Compatible with copper alloy, brass, and phosphor bronze Terminals, it ensures excellent electrical conductivity and long-term contact reliability across all 66 positions, supporting both analog audio signals and digital data transmission.

Key Product Information

Engineered for Automotive Reliability

The TS30283-66P-21-1 is built to withstand the demanding conditions of automotive Electrical Systems. Its reinforced housing maintains structural integrity under thermal cycling and mechanical stress, ensuring long-term performance in under-dash, engine bay, and cabin-mounted installations. The precision molding guarantees consistent terminal alignment and smooth mating, minimizing wear and maximizing connector lifespan.

The locking feature enhances connection security, preventing signal interruption in high-vibration environments—essential for maintaining audio clarity, data accuracy, and system stability in modern vehicles. The blue color serves as a quick visual identifier, reducing the risk of mis-mating during assembly, maintenance, or repair operations in multi-connector setups.
