The "A" pillar airbag is attached using strips of tape (there may be other hidden fixings too) so I VERY CAREFULLY threaded my cable behind the airbag so it would not get in the way if it ever went off. I did not interfere with the airbag at all. I couldn't remove the "A" pillar trim fully, it just wouldn't completely detach at the bottom for some reason so I didn't wanna force anything so it made getting the cable through to the fusebox difficult at first. However, I threaded a piece of stiff wire through from the top until it came out at a point below the dash where I could grab hold of it, taped the dashcam plug to it & then gently pulled it up through before carefully threading it up under the airbag & tucking it under the headliner. After I had made the connections at the fusebox there was lots of spare cable so I neatly reeled it up & cable tied it to the metal framework behind the removable panel on the left of the dash.
