As said above get 2 add a fuse if you are using battery saver device like Blackvue power magic pro(for parking mode). Run the wires up beside the rearview mirror, tucked into the headliner and down the A pillar. From the A pillar you can tuck the wire into the weather stripping and down into the cabin. You can remove the plastic rocker panel trim piece and the other corner trim piece, both which will just pop off. From here you have access to the fuse box(piggyback off the fuse) and will be able to tuck excess wiring behind the trim panel that would be by your left foot.
