Hi Doberman19. If it's a BlackVue Dashcam solution you've got with a PowerMagic Pro box. Then I'll see if I have any old photos of my config when I had that accessory installed (now moved to a Pittasoft Blackvue external battery solution instead as I wanted longer parking mode)
Off the top of my head I think I connected the BATT(+) yellow wire for a permanent 12 Volt connection (when the ignition is off) via an "add a fuse" accessory to the fuse 13 location (Rain Sensor). As I'm sure that circuit retained 12 volts with the ignition off. A check with a multimeter would confirm of course.
I avoided anything to do with safety systems e.g. airbags, car alarm (interior monitoring), ABS, ESP.
The ignition power lead for the Dashcam I connected to fuse location 24 (Cigarette Lighter).
