The harbor breeze fan I purchased has only one white and one black wire for connection. There is a third black wire taped off. I want to connect to an existing wire box containing a white,black,red and green wire. I need the fan and light kit to operate independently as did the fixture I removed. Any answers to the proper connection

What do the instructions say??

I have never seen a new fan with a wire taped off.

The instuctions say nothing regarding the taped off wire. They only instruct you to install the fan with the existing black and white connection. I presume this is the third wire that operates the fan motor should you choose to independently operate from a light switch

THEY ONLY INSTRUCT YOU TO INSTALL THE FAN WITH THE EXISTING BLACK AND WHITE CONNECTION. I PRESUME THIS IS THE THIRD WIRE THAT OPERATES THE FAN MOTOR SHOULD YOU CHOOSE TO INDEPENDENTLY OPERATE FROM A LIGHT SWITCH
This is how most fans are, but the fan wire is usually black and the light wire is blue.
Like I said, I have never seen a taped up wire.
Sorry I cannot be of more help.
