There isn't much room or wire to mess with near the ballast so I don't want to do it again unless it would prevent me from ruining the light.
Maybe you can solve that problem in way that you made some kind of ''puck'' that you would screwed on upper surface of lid thick arround 25mm (inch) .
Yo can made a little bigger hole in that ''puck'' to keep existing switch in original lid position and you route cable inside it in 90° and then finish with gland as suggested ?
