ok a bit of bravery and a small amount of damage
I levered the switch plate up using a terminal driver, just edging it up all along. Then POP it was off !
I recommend unclipping the switch units rather than disconnecting the loom as they have to come off anyway.
As for wrapping, blimmin fiddly but quite pleased with the result. I might strip and redo at a later date but good for now.
Not sure how to wrap the switch wells......
Ok what else can i mess about with.......
