So my a.c works all the time and it works great and its cold and my condensor fan works. But i just need to know what that other connector is for on the condensor fan cause i only have one and it is for the fan to turn it on but can anyone let me know what the other one is for please cause i dotn have one and i really wanna know what it is for please help.
