Relating to the 2010-12 L322 4.4 TdV8. Does anyone know if the fuse marked 'spare' at No' 16 in the glovebox fusebox is a switched ignition live? Asking as I want to fit a piggy back fuse to power a dash cam. Thanks in advance.

I've looked at the wiki re fitting dash cams, but that seems to relate to the earlier vehicles fitted with standard blade fuses and the later ones have mini blades and a different layout. Drives:

The wiring schematic shows the fuse is ignition switched and supplies the engine bay auxiliary fuse panel where it powers the relay for the heated washer jets.

Brilliant GraemeS, thanks. I'm hopeless at reading wiring schematics. This looks like an ideal place to piggy back. Drives:

Just to complete this, at long last I got around to hard wiring the dashcam, used fuse 16 to piggyback from and all works fine. Drives:
