The last time I installed them I left a whip of greenfield buried in the wall. When the cabinets were being hung I drilled a 1/2 hole in the bottom lip of the back of the cabinet. I ran that out to a single gang wire mold box. I transitioned in that box to wire mold and ran the whip of the puck in wire mold.I mounted all of this under the cabinet where you could not see it,but it could have been done in the very back of the cabinet too.
