Hello DDCN fans for Luminous, their connector is compatible with DDCN models from 98 to 2016, or they were specifically made for this model, but compatible with models from 97 and below The fans have two speeds, currently I have disconnected the thermal switch and set it to the second speed Tell the person installing it for you that if they want to operate it with a switch for first and second speed, they should adjust it accordingly Fans are guaranteed, God willing Private message or WhatsApp
