Abstract: A fuel injector for an internal combustion engine includes an injector body in which there are positioned an actuator, a control valve, and a needle guide. The actuator actuates the control valve, the control valve controlling an injection needle sliding the needle guide between an open position in which injection is permitted and a closed position in which the injection of fuel is prevented. The injector additionally includes a first electrical connection extending from the needle guide to a metal that are internal to the injector, and a metal extension extending from the metal ring to a connector pin accessible from the outside of the injector, so that an electrical signal indicative of the position of the needle can be transmitted from the needle guide for the needle to the connector pin.
