66-Pin White Female Wire Harness Connector – TS30283-66P-21-2 with Lock for Toyota Audio and Control Systems

The TS30283-66P-21-2 is a high-density female wire harness connector engineered for seamless integration into Toyota vehicle electronics, particularly in audio, infotainment, and control module applications. As the mating counterpart to the male TS30283-66P-11-2 housing, this white 66-pin connector ensures secure, reliable connectivity in factory-installed and aftermarket wiring systems. Designed with a built-in locking mechanism, it prevents accidental disengagement caused by vibration or mechanical stress, making it ideal for use in demanding automotive environments such as engine compartments, dashboards, and marine installations.

Manufactured using high-performance thermoplastics—PBT+GF15% or PA66+GF30%—this connector delivers excellent resistance to heat, impact, and chemical exposure. Its precision-molded housing supports consistent terminal alignment and long-term durability, supporting stable signal transmission across all 66 circuits. Whether used in passenger cars, yachts, UTVs, or industrial vehicles, the TS30283-66P-21-2 meets the rigorous standards required for modern automotive Electrical Systems.

Technical Specifications

Reliable Performance in Automotive Applications

This female 66-pin connector is specifically designed to maintain stable Electrical Contact in high-vibration and temperature-variable environments. The locking feature ensures that once mated with the corresponding male housing, the connection remains intact even under prolonged stress—critical for safety and functionality in vehicle control networks.

Its compatibility with copper alloy and phosphor bronze Terminals guarantees low contact resistance and high conductivity, essential for transmitting audio signals, data packets, and power across complex vehicle subsystems. The white housing provides easy identification during assembly and servicing, reducing installation errors in multi-connector setups.
