The Bosch EV1 (1 X Female) with cable, commonly referred to in the automotive industry as an EV1 Pigtail, is a pre-assembled 2-pin electrical connector. It is designed to provide a "plug-and-play" solution for repairing damaged wiring or building custom harnesses without the need for specialized crimping tools.
Technical Description
Connector Type: Female Jetronic / Minitimer (Junior Power Timer).
Wiring: Usually pre-fitted with two 18 AWG or 20 AWG automotive-grade copper wires.
Lead Length: Typically measures between 10 cm and 15 cm (4 to 6 inches).
Locking System: Equipped with a metal spring wire clip that provides a secure, vibration-proof "click" when connected to a male terminal or fuel injector.
Sealing: Features internal silicone gaskets and heat-shrink or rubber boots at the wire entry points to achieve an IP67 waterproof rating.
Common Applications
This pigtail is a universal standard for many European and American vehicles. It is compatible with:
Fuel Injectors: Fits Bosch EV1 (Design II and III), Siemens, and Rochester injectors.
Engine Sensors: Used for coolant temperature (ECT) sensors, intake air temperature (IAT) sensors, and oil pressure switches.
Solenoids: Often used for boost control solenoids (like the MAC 3-port) and idle air control valves.
Vehicle Brands: Extensively found in BMW, Audi, VW, Volvo, Ford, and GM (LS1/LS6 engines).
Benefits of the "With Cable" Version
Ease of Installation: Since the terminals are already professionally crimped inside the housing, you only need to strip and splice the tail ends to your existing harness using solder or butt connectors.
Reliability: Factory-crimped terminals reduce the risk of "loose pin" issues often caused by improper DIY crimping.
Versatility: Ideal for emergency roadside repairs or for creating adapter harnesses (e.g., converting an EV1 harness to an EV6 injector).
