video camera recorder needs a power source

zmyride

I'm thinking of installing a car video camera recorder for my Z. it's a tiny camera which fits snuggly behind the rearwheel mirror. The camera needs a power source, so i'm thinking of looping the wire along the windshield through the drivers side's edge(frame or whatever you call it)

the thing is if i open the plastic cover, will it damage the airbag or will the bag pop out? sorry i've never done this before so i have to be cautious.
