I have a working receptacle that gas 3 romex wires connecting to it. Set 1 is a 14/2 and set 2 is 14/3 and set 3 is 14/2. The only hot wires are the red and black from set 2. Here is how the outlet is wired. Set 1 white is connected to bottom left of receptacle and black is connected to red of set 2. Set 2 white is connected to top left rear of the receptacle and black is connected to the top right of the receptacle. Set 3 white is connected to the top left and black is connected to the bottom right. My goal is tone remove this outlet and install a gfi about 3 feet higher.
