you have to route the power cable up that way to the main camera, you could also just use the included stick on zip tie fasteners alongside the A -pillar plastic trim ( on the windecreen ) then the wire shouldent be in the way as the airbag deploy in the other direction, and the chance of the wire getting dislodged and whipped into your eye should be minimal.
It is not a super clean way of installing, but it should be enough out of the way for most to not notice it or do anything about it.
In my car thats a cheap ass Suzuki i can actually push wire in between the plastic trim and the windscreen using no tool, but i dont have a airbag there as its above the door and deploy downward.
Anyway even with a airbag in the A pillar if you push in wire on the windscreen side of the plastic trim it ahould be out of the way of the bag when it deploy in the other direction.
The main thing must be to keep things out of the direction the airbag deploy, at least to the back of it should be just fine, at least in my book of simple partly digital living.
