Running wire down the A pillars (07, RX350)

[exmeaguy]

I have a Valentine 1 and I tapped into a hot wire inside the overhead console several years ago.  I just got a dashcam and I am thinking of running the hot wire down one of the A pillars to the fuse box instead of the overhead console, not having a wire diagram of what else I can tap into.  Has anyone done something like this before?  Did you have any problems pulling the A pillar covers off?  I am concerned about messing up the air bags or whatever lurks behind it.

Any help is appreciated.

I cant remember but are there airbags in the post?  If so be very careful.  If it were a Ford F150 I would say no sweat, done it many times.
