70mai a200 G sensor installation

[Thingy44]

Hey guys, I just bought a 2013 postlift ZE0 without a rear cam, and I decided to buy the A200 dual set. I dunno if I will be able to connect it to the fuse box. That nissan is my first car and all the YouTube guides for the dash cam are for 'normal' cars. Could someone help me out here? How do I connect those cameras to the car? (I'm buying the 70mai UP02 adapter)
