Hello people, as the title says, what I intend to do is to take the engine out of a 3-speed kitchen extractor and place a single-speed forger at the end of the duct. The idea is to be able to command it from the extractor button. How do I have to make the connections? Since the new engine has 3 wires (neutral live and ground) and the original 5. I want to put it straight, I'm not interested in the speeds. Thank you
