The four wires of the car engine cooling fan relay are: the ground wire from the temperature control switch, the permanent live wire, the relay output wire, and the ignition live wire. Connection wires of the fan relay: The four wires of the car engine cooling fan relay are: the ground wire from the temperature control switch, the permanent live wire, the relay output wire, and the ignition live wire. Function of the relay: Relays generally have a sensing mechanism (input part) that can reflect certain input variables (such as current, voltage, power, impedance, frequency, temperature, pressure, speed, light, etc.); an actuating mechanism (output part) that can control the "on" and "off" of the controlled circuit; and between the input part and output part of the relay, there is an intermediate mechanism (driving part) that couples and isolates the input, processes functions, and drives the output part.
