Hello I need help.
I have bought the blackvue front and rear Dash cam with the power magic pro but the power magic pro needs hard wiring into the interior fuse box. But I don't know which two fuses to take out to then put fuse taps in to replace them. Does anybody know? Or which way round to plug them in? Also I'm not sure which screw to ground the other wire too that needs grounding. can anybody help me?

It shouldn't need two fuses?

I'd normally tap into the radio fuse. That way if there's a problem you only loose your radio.

Ideally, look for a factory ground point, but as it's just a dash cam, just about any large bolt will work. Possibly the OBD plug bracket.

There’s a good solid earth just in front of the airbag ecu behind the heater box. 10mm nut

Another possibility is the boot for the bonnet release catch works fine for me

This is the wiring of a NextBase dash cam into the fuse box in the glove compartment of my 500.

The earth wire is fixed to a metal bolt underneath the LHS of the glove box.
