Here is a tip: I watched a lot of install videos for mangoal and other dashcams where you have to run a wire around the headliner for the rear camera. It seems very simple to just tuck the wire behind the a-pillar and c-pillar covers BUT there are air bags behind those covers. You should take the covers off and thread the wire behind the airbags so that if in the event they deploy, they won't be slinging your cameras around.
