12 Way White Male Quadlock Automotive Electric Plug Backshell Cable Clamp 1-1355524-3 – TSVW12-12P-11WT High-Reliability Connector for Vehicle Audio & Control Modules

In the world of automotive Electrical Systems, precision and durability are non-negotiable. The TSVW12-12P-11WT is a high-quality 12-pin white male Quadlock backshell engineered to serve as a direct replacement for the 1-1355524-3 connector. Designed for seamless integration into factory and aftermarket audio, infotainment, and control circuits, this connector delivers consistent performance in cars, yachts, UTVs, and industrial vehicles. With its rugged construction, environmental sealing, and secure locking mechanism, it ensures stable signal transmission even under demanding operating conditions.

Precision 12-Way Male Plug for 1-1355524-3 Replacement

The TSVW12-12P-11WT is a white male Quadlock connector designed to match the functionality and fit of the 1-1355524-3 OEM part. Its 12-way configuration supports full signal and power routing for vehicle audio systems, control modules, and sensor interfaces. The white housing provides easy visual identification during installation and maintenance, reducing errors in complex harness assemblies. Whether used in new production, repair work, or system upgrades, this connector offers reliable performance and plug-and-play compatibility with standard wiring setups.

Rugged Thermoplastic Construction for Long-Term Durability

Built from either PBT+GF15% or PA66+GF30%, the TSVW12-12P-11WT features a glass-reinforced housing that resists impact, heat, and chemical exposure. These engineering-grade plastics maintain structural integrity across extreme temperatures—from freezing cold starts to prolonged exposure in hot engine bays. The white color not only enhances visibility but also reflects UV radiation, making it ideal for installations exposed to direct sunlight, such as marine dashboards or off-road vehicle interiors.

Integrated Sealing for Environmental Protection

Each terminal cavity is equipped with a pre-molded mat seal and diaphragm that compresses around the wire insulation when Terminals are inserted. This creates a watertight, dustproof barrier that prevents moisture ingress, corrosion, and contamination—common causes of intermittent faults and signal degradation. The sealed design ensures long-term reliability in wet, salty, or dusty environments, including marine vessels, agricultural machinery, and all-terrain vehicles.

Secure Terminal Retention with Wedge-Lock Technology

To prevent terminal displacement due to vibration or mechanical shock, this connector employs a two-piece housing with a secondary wedge lock. After crimped terminals are loaded into the primary housing, the wedge is inserted to lock them firmly in place. This dual retention system eliminates backout risks and ensures continuous Electrical Contact, even in high-vibration applications like engine compartments or rough terrain driving. The result is a robust, service-free connection that maintains signal integrity over time.

Versatile Terminal Compatibility for Custom Installations

The TSVW12-12P-11WT accepts copper alloy, brass, and phosphor bronze terminals, offering flexibility in conductivity, cost, and mechanical strength. It is compatible with standard automotive crimping tools and widely used in both OEM manufacturing and aftermarket repairs. Ideal for building custom harnesses, replacing damaged connectors, or upgrading factory audio systems, this male plug provides a dependable solution for technicians, installers, and system integrators.

Complete Mating Pair with Female Receptacle TSVW12-12P-21WT

This male backshell is specifically designed to mate with the TSVW12-12P-21WT female receptacle, forming a fully sealed and mechanically stable connection. Together, they create a reliable interface for transmitting audio signals, power, and control data in automotive and marine electronics. As part of a scalable Quadlock series, these connectors are available in various pin counts and housing colors (white, black, green, brown), enabling color-coded wiring schemes and modular system design.

Applications Across Automotive and Industrial Sectors

Typical uses include:

• Direct replacement for 1-1355524-3 in car stereo and infotainment units

• Repair and retrofitting of factory audio harnesses

• Marine radio, GPS, and entertainment system wiring

• Control module connections in UTVs, ATVs, and farm equipment

• Custom cable assemblies for OEM and aftermarket brands

Its sealed, vibration-resistant design makes it suitable for both protected cabin environments and exposed outdoor installations.
