The fabricator installed the quartzite and left wires for my undermount lights exposed. I called an electrician to install the lights, but he said he couldn't because the wire needs sheathing. The sheathing and connectors are behind the backsplash. The third picture is what the wire protection looks like. The fabricator said they will cut bigger holes, but the holes will look so big because the connector is so big.

Ideas welcomed
