I've got a 12-2 wire sitting loose in an attic. It's connected to a switch on the ground floor. I'm planning on running a ceiling fan from this wire using 12-3. I'm assuming that I can splice both the black and red from the 12-3 to the black in the 12-2 and white to white. Is this correct? Also, since there is no ground wire in the existing 12-2, what do I do with the ground in the 12-3? Connect it to the metal junction box that I plan to use? Thanks for any help.
