    Automotive relay wiring method

    The relay has a four-leg relay and a five-leg relay. Let's talk about the four-leg relay. First find out which of the four pins of the car relay are the coils, and which two are the contacts that are connected as shown. The two pins are insulated between normally open contacts 3 and 4. The other tw... read more
