Auris Dash Cam Wiring

Hi folks :)

I looking to hard-wire a Dash cam in on my 2011 1.6 petrol Auris

The easy bit looks like pushing the wiring under the roof lining across to the A Pillar, the latter kind of concerns me a bit, under the A pillar is sleeping an Air bag, the last thing in the world I want to do is wake this air bag up, I hate sudden unexpected explosions

Any help from anyone with educated opinions or from someone who has trod this path before would be greatly appreciated

Thanks
