Basically i need to get a fuse tap on top of this, right? Thanks for the links.

I have that exact device powering my dash cam (well, I have the single USB port version). It works perfectly. I have it wired into the fuse box and it's hidden entirely behind the dashboard trim.

Edit: actually it's this one that I bought.

I've used little usb direct hardwire dealies like this guy before.

Just power it of switched 12v, and hide it all nicely behind the dash.

Or this one will give you direct micro usb, to cut out a cable.

edit : I'm sure there are waaaay cheaper options that do the same thing. Those were just easily found :)

Can I use this?

I never touched a fuse box before. Quite handy with computers though. What tools will I need?
