14 Way Female Black Automotive Ignition Connector for BMW Car 1452829 – TS30357-14P-21 High-Reliability Sealed Housing for Engine Management Systems

Engineered to meet the rigorous demands of modern automotive electronics, the TS30357-14P-21 is a 14-way female black connector designed for critical ignition and engine control applications. Compatible with systems requiring the 1452829 specification, this high-performance housing delivers secure, vibration-resistant connections essential for reliable vehicle operation. Built as part of a robust sealed connector series, it ensures stable signal transmission in ignition modules, fuel injection systems, and ECU interfaces—particularly in BMW and other premium vehicle platforms where precision and durability are paramount. With its advanced sealing, dual retention design, and compatibility with industrial-grade Terminals, this connector is ideal for OEM replacements, performance upgrades, and custom wiring solutions in cars, yachts, UTVs, and off-road machinery.

Precision-Engineered for Critical Automotive Ignition Systems

The TS30357-14P-21 is specifically designed for use in automotive ignition and engine management systems where signal integrity and mechanical stability are non-negotiable. As a female 14-way connector, it ensures a secure, low-resistance connection between engine control units (ECUs), ignition coils, and sensor arrays. Its robust construction and sealed design make it particularly suitable for under-hood applications exposed to heat, vibration, oil, and moisture. Whether used as a factory replacement or in a custom performance harness, this connector delivers the reliability needed for smooth engine operation and long-term durability.

Advanced Sealing with Per-Circuit Mat Seals

Each terminal cavity is equipped with a molded-in mat seal featuring a protective diaphragm. When a terminal is inserted, the diaphragm is pierced, forming a tight seal around the wire to block moisture, dust, and contaminants. This prevents corrosion and electrical shorts—common causes of engine misfires and sensor failures. In the event a terminal is removed during maintenance, a sealing plug should be installed to maintain the housing’s environmental protection, ensuring continued reliability across the vehicle’s lifespan.

Secondary Locking Wedge for Vibration Resistance

Unlike standard connectors that rely solely on terminal latches, the TS30357-14P-21 uses a two-piece housing system with a secondary locking wedge. After terminals are inserted, the wedge is slid into place, applying uniform pressure to all contacts. This dual retention mechanism prevents terminal backout caused by engine vibration or thermal cycling—a critical feature in high-performance and heavy-duty applications. The result is a connection that remains stable and secure, even under extreme operating conditions.

Durable Materials for Harsh Under-Hood Environments

Constructed from either PBT+GF15% or PA66+GF30%, the black housing offers excellent resistance to high temperatures, impact, and chemical exposure. These glass-filled thermoplastics maintain dimensional stability and mechanical strength across a wide operating range, making them ideal for engine compartments and other demanding locations. The housing’s robust design ensures long-term performance in BMW and other European vehicles where connector quality directly impacts system reliability.

Optimized for Multi-Row, High-Density Wiring

With a compact 4.0mm pitch and multi-row layout, the TS30357-14P-21 maximizes pin density while minimizing space requirements. This makes it perfect for modern vehicles where electronic modules are tightly packed and wiring complexity is high. The organized contact grid simplifies assembly, reduces errors, and supports clean, professional harness builds for both OEM and aftermarket installations.

Compatible with High-Conductivity Terminals and Standard Headers

The housing accepts a range of terminal types, including copper alloy, brass, and phosphor bronze—ensuring flexibility in conductivity, cost, and mechanical performance. It also integrates seamlessly with standard PCB Headers and mating male plugs, enabling easy integration into existing systems. Whether replacing a worn connector or building a custom diagnostic interface, this housing provides a reliable foundation for a factory-matched connection.

Ideal for Automotive, Marine, and Off-Road Applications

Common applications include:

• Ignition system connectors for BMW and other European vehicles

• Engine control unit (ECU) and sensor harnesses

• Marine engine management and control panels

• UTV, ATV, and agricultural machinery wiring

• OEM and aftermarket performance upgrades

Its modular, serviceable design supports both small-scale repairs and large-volume production.
