Bow Light

Hello All,
Just posted a few new pics in the gallery and this is pretty much it as far as refurbishing/changes go.
My bow navigation light is inop and there appears to be a short in the wiring. The problem I have is from the cabin I can't locate the wiring that goes from the light to the dash. is it up under that headliner? Or behind the side panels next to the bunks? I could just run a new set of wires but they would be visible from inside the cabin. Any help would be appreciated.
