permanent and switched live fuse

[grammy]

I am trying to wire up a dual dashcam with hardwire kit I have fed the wires down to the interior passenger footwell fuse box but not sure which fuse to tap with for switched live and permanent live.

You need a test light to check .

Set test meter to dc 12v find body earth screw into inner wing, or a handy earth point (numerous brown wires ) hold black - probe on it
Turn ignition on touch fuses with red probe until you can find one that stays live when you switch ignition off... you have found your permanent feed
do the same until you lose your voltage...you have found your switched line.

I couldn't find any switched live and permanent Fuses in the Footwell Fusebox, I used the one at the End of the Instrument Panel, can't remember which Fuses I used though, as it was two cars ago!

Some don't have any , I had to use a 12v from the glovebox light on my c207. My glc 350 had a tiny tiny connection in the driver's side panel I took a source from.
