Hi all, 

Sorry if this has already been answered! 

Are all the holders in the fuse box live regardless of whether they are empty or "unassigned". 

I am simply looking for the best position to fit my dash cam piggyback fuse unit and hoping an empty space would work. 

Thanks. 

Probably. Some may be ignition-switched though.
Why not just use a DVM to find a suitable slot?

 

 

Have a look here! 

Had this same question! Fuse 3 (in 2012/2013 model) is always powered and is not a critical system (radio), so if comes loose from piggy back you’re not in too much trouble. Check your model and fuse is not essential though.

Thanks for the replies folks. Having discovered the ridiculous position of the fuse box I have decided to power the dash cam from the supply to the cigarette lighter. As the socket is switched on with the ignition the camera will power up when driving.

Camera now working fine and Satnav fitted to the redundant cup holder thingy and plugged in to the adjacent power socket when required. 👍😁
