VW 2-Pin Injector / Solenoid / Camshaft Connector OEM 4H0973702 | Type A B C D Female
VW 2-Pin Injector / Solenoid Valve / Camshaft Connector – OEM 4H0973702 | Type A, B, C & D Female
The OEM 4H0973702 is a 2-pin waterproof connector used across multiple Volkswagen engine management circuits – fuel injectors, solenoid valves, and camshaft adjustment actuators. Volkswagen’s VAG Group engineering uses a family of 2-pin connectors with the same base part number but different housing geometries (Type A, B, C, D) to prevent mis-mating between adjacent circuits in the engine harness. Available in all four types, bare or with 15cm pre-wired leads.

VAG Group Type Coding – A, B, C, D Explained
Volkswagen’s VAG Group uses a systematic type-coding approach for connector families. The 4H0973702 base number covers a family of 2-pin connectors used in the engine bay, all with the same electrical function (power + ground/signal) but different housing geometries. The type letter (A, B, C, D) changes the locking tab position, housing width, or terminal spacing to prevent mis-mating between adjacent connectors in the engine harness. This is critical in VAG engines where fuel injectors, camshaft solenoids, and purge valves may all use 2-pin connectors within centimeters of each other. Installing the wrong type will prevent the connector from fully seating, leaving the circuit intermittently open.
Application-Specific Notes
- Fuel Injector (GDI/MPI) – Carries injector solenoid power and ECU-controlled ground. Failure causes P0201–P0204 injector circuit faults and cylinder misfires.
- Camshaft Adjustment Solenoid (VVT) – Carries the variable valve timing solenoid control signal. Failure causes P0010/P0011 (camshaft position actuator circuit) and timing-related misfires.
- Solenoid Valve (EVAP/Turbo) – Carries solenoid power and ground for EVAP purge or turbo wastegate control. Failure causes P0443 (EVAP purge valve) or boost control faults.
Variant Guide
- Type A Female / A Female 15CM – Type A housing geometry
- Type B Female / B Female 15CM – Type B housing geometry
- Type C Female / C Female 15CM – Type C housing geometry
- Type D Female / D Female 15CM – Type D housing geometry
Identify your type by comparing the locking tab position and housing profile of your original OEM connector, or cross-reference via ETKA (VAG parts catalog).
