My ‘16 Wildcat 327ck is prewired for an a/c in the front bedroom. I would like to put a Maxx Deluxe fan in place of the current skylight/vent. If I remember right, the original cheap vent fans run off 12 volt? The wires in the bedroom look bigger then normal 12v to me (but I am no electrical expert). Anyone know if I can use the black/white prewires for the Maxx Fan?
