I made lables and revised / corrected the fuse layout legends, note the engine vs body fuse carriers are flipped the wrong way round in the handbook or fuse box top label
(I should really label my aircon as 'spare')
I had that diagram key problem on my previous Plus 4. I'll have a closer look at my Roadster diagram and see if I need to do the same.
