I installed a couple of ceiling lights in my C30 and fully hid all of the wires. I used a combination of methods. I found that there is a void between the exterior deck house and the interior liner. I have a mirror made from an old bronze opening port that is mounted into a hole drilled through the interior liner. I also have a fuel gauge display mounted through the cabin house so that I can read fuel level while filling. By removing these two holes, I was able to pull wire up between the liner and house. I then removed the trim that ran down the inside edge of the overhead and drilled a hole behind the end of the trim. Using a fish tape, I pulled the wire from the fuel gauge to this new hole. I then used a router table to plow a dado into the back of the trim out to where I was installing the light. The end result was new cabin lights with no visible wires in the house.Has anyone tried installing one of these? My Catalina 310 has limited access to the area above the salon so even getting some wiring in there would be a challenge.
We added another light fixture to the center of the saloon but there was no way to snake in a wire. we mounted the light and then made a piece of 3/8"x1" trim with a 1/4"x1/2" dado in the back and surface mounted it over the wire run to the bulkhead where we already had a bulkhead light.
