3-Pin VW Waterproof 3.5mm Connector – Carburetor & Electronic Fuel Injection (EFI) Harness Plug

A 3-pin waterproof 3.5mm pitch connector for Volkswagen carburetor and electronic fuel injection (EFI) harness plug applications. Used on VW vehicles during the transition from carburetor to EFI systems (late 1980s to mid-1990s), where the same 3-pin connector format was used for both carburetor solenoid and fuel injector harness connections.

Carburetor vs EFI – Same Connector

VW used the same 3-pin 3.5mm connector format for both carburetor solenoid valves (idle cut-off solenoid, enrichment solenoid) and early EFI fuel injector harnesses. This connector is compatible with both applications:

• Carburetor applications: Idle cut-off solenoid, cold start enrichment valve, choke solenoid
• EFI applications: Single-point injection (Mono-Jetronic) injector harness, fuel pressure regulator solenoid

Compatible VW Applications

• VW Golf (MK1/MK2): Carburetor solenoid and early EFI harness
• VW Jetta (MK1/MK2): Shared platform fuel system connectors
• VW Passat (B1/B2/B3): Carburetor and Mono-Jetronic EFI harness
• VW Polo (86/86C): Carburetor solenoid wiring

FAQ

Q: Can I use this connector for both carburetor and EFI applications?
A: Yes. The 3-pin 3.5mm format is used for both carburetor solenoid valves and early EFI injector harnesses on VW platforms. Verify the pin count and pitch match your application before ordering.

Q: What crimping tool is needed?
A: Use a ratchet crimper rated for 18 AWG (0.5 mm²) – Engineer PA-09 or equivalent.
