Original VAG 4D0 971 993

Terminals and seals are included

The Component: Genuine VAG OEM 4D0 971 993 (4D0971993 / 60404101) 3-Way sealed female automotive connector flat plug housing (Black).

Series Taxonomy: VAG 2.8mm Sealed Interface System (FCI / Aptiv Manufacturing Platform). A highly robust, industrial-grade single-row interconnect footprint specified widely across German engineering platforms for secure powertrain, body management, and electronic signal routing.

Terminal Interface: 3-pin single-row inline cavity block configuration engineered explicitly to house 2.8mm wide female flat receptacle terminals (such as the Delphi/FCI HPCS 2.8 series or VAG cross-reference contacts).

Locking and Sealing Security: Environmentally sealed to an IP67 rating with a high-durability continuous operating threshold certified from -40 to +125 degrees Celsius. Features an integrated primary sliding matrix lock or contact locking mechanism to provide unyielding terminal position assurance (TPA), preventing pin back-out under severe axial line pull. Mating security relies on a heavy-duty mechanical locking latch arm that clicks firmly past the device interface tab to combat severe chassis vibration profiles.

Mating Complement: Connects wire-to-device or inline wire-to-wire by mating directly onto corresponding 3-way male tab headers, sensor interfaces, or matching male housing counterparts across Volkswagen, Audi, Seat, Skoda, and Porsche platforms.

Common Applications: Extensively specified as a premium factory wire-harness repair pigtail across the VAG (Volkswagen Audi Group) and Porsche network ecosystem. Most frequently deployed as the primary harness-side interface for fuel tank pressure sensors, fuel injectors, camshaft and engine position sensors, ambient air temperature units, airbag sensors, and door handle electronic switches. Highly prone to fatigue-driven locking arm breakdown, structural latch fracturing, or engine bay thermal fatigue during routine component maintenance or diagnostic loom testing.

VAG 4D0971993 3-Way 2.8mm Sealed Female Fuel Pressure and Engine Position Sensor Plug Housing

Restore absolute circuit continuity, eliminate erratic sensor dropouts, and reinstate premium factory-standard environmental insulation inside your vehicle's harness loom with the genuine VAG 4D0971993 3-way sealed female connector plug housing. Precision-manufactured to strict Tier-1 original equipment automotive engineering parameters, this 3-pin 2.8mm contact carrier block is an industry-essential component for executing durable auto-electrical wire restorations. Configured with a clean single-row cavity matrix on a tight contact raster, it establishes a solid, zero-resistance connection path capable of managing critical powertrain sensor telemetry and low-voltage electrical distribution safely without risking resistance scaling.

The 4D0971993 carrier block is injection-molded from a premium, heat-stabilized Polybutylene Terephthalate (PBT) compound finished in a factory black tone, ensuring outstanding impact defense, high dimensional tracking accuracy, and total immunity to structural degradation across extreme engine bay and fuel tank environments. Working in absolute uniformity with internal compression seals and individual rear-wire cable seals, it forms a secure defensive barrier that isolates low-voltage signal paths from moisture tracking, chemical fuel vapors, engine oils, and abrasive dirt. This authentic component allows independent auto-electrical specialists, VAG diagnostic garages, and custom loom builders to deliver traceable, factory-correct harness solutions.
