Bosch 3 pin connector

Bosch 3 Pin Jetronic Connector

The Bosch 3 pin Jetronic connector is a replacement plug for Bosch Junior Timer family sensors and actuators commonly found on Japanese and European engine management systems. This connector kit is most often used on Bosch throttle position sensors, idle air control valves, and ignition modules requiring a 3-pin connection.

This connector is part of the Bosch Junior Timer series (Bosch part number 1 237 000 039) and features a centre guide design. Check the guide position on your existing connector before ordering, as Bosch uses multiple guide configurations across different sensors.
