Similarly for the Golf mk7 (from: 0:43min)

Regarding choosing the path of the power wire on the A-pillar some are advocating that it can tuck just tuck under the trim without removing it. Having watched the deployment of the curtain airbags of a Octavia mk3 on youtube I would strongly recommend removing the trim completely and securely fastening the wire to the existing cable loom. Any loose wire just tucked inside the trim or door seal may seriously impair the deployment of the airbags, perhaps slicing the bags as they expand at enormous speed. Please do yourself a favour and watch this video (especially from 1m:35s). It would seem that those pesky 2-stage clips used to hold the trim to the A-pillar are designed to release enough space for the airbag to pop out without the whole trim flying off with it. It might be a good idea to replace these clips with new ones if you pull them out.
