You can't see the wires but if you look closely at the pic of my fan you can see a small seam (covered by seam tape) running to the upper cabinet. That seam is just wide enough to neatly tuck in the 2 wires. To help hold them in place I used a hot glue gun and then put the seam tape over the wires to hide them. I had some
paint left over from when I painted the ensolite so it worked well.
For the running of the wires....
I ran the two wires from under the cabinet/sink up through the chrome pipe that also carries the wires for the 2 puck
lights and 120 volt flourescent
light. Then along the back side of the flourescent
light and into the cabinet where they run along where the cabinet meets the roof, then they go into that seam until they run under the plastic trim ring and into the vent.
