Many thanks for some quick responses.
H3lsing, thanks for the diagram. However the trim looks very different on mine. I'm not sure if i have a different interior package or slightly different model. (i've only owned a Focus for a few weeks)
James, your clues have got me a lot closer worked out the grab straight away. Will have to wait until daylight to have a go at the handle but it sounds like we're talking about the same thing.
Many thanks
Rich
