Does it matter which fuse is used? I presume they all become live when ignition is switched on but do I need to use one that stays live with ignition off (for parking video) and how do you differentiate with no suitable tools?
If you re-read Nicks first post he explains what he has used and which fuse ways he has connected the devices to.
I removed my device yesterday but did not take am images as it was just a temporary fix.
