Nice to know my concern on wiring integrity is unfounded!
My eight year old son is astonished to learn the instrument switches are not meant to be illuminated on pre 77 Mogs. He quite practically suggested sticking various material to each switch so it can be identified when driving at night; feathers, glazier cherries, sandpaper and the like spring to mind. Would be a nice way to go that extra mile when personalising one's Morgan.
