Here's how I installed my dash cam. I used the cigarette lighter port under the center of the dash to power the camera. The camera itself just sticks on the windshield using double sided tape. I made sure to leave a little bit of a gap to make sure I could slide my camera off its mount. The wire tucks in the top of the windshield easily. Just need to press with fingers. I chose to put it on the drivers side so the buttons are easily accessible. The windshield is large enough so even though its on the drivers side its still very much out of the way. The wiper blades also wipe higher on the driver side so the windshield is cleaner there. I also had to move it away from the review mirror assembly because it was blocking the view of the camera.
When you get to either side I removed the pillar cover. to do that you first use a small screw driver to remove the ABS plastic thing. Underneath that is a torx t-30 screw that needs to be removed. Once the screw is removed you should pull the rubber molding away from the door frame. Just grab it and pull away with your hands and it should slowly start coming off. Just get enough of it off so you can work with that area. The whole thing does not need to be removed.
Once the molding is out of the way you can start to pry the pillar cover off staring from the top. There are these blue fasteners that are used to keep it on the carbon fiber. It takes a little bit of force, but they will snap off. I reached my hand down the cover to put less stress on it. Be careful not to pull so hard that you angle the pillar cover to far away from the pillar. there are vertical tabs at the bottom of pillar cover that could possibly break if you twist them too much. Once both fasteners are snapped off the pillar can be removed from the dash by pulling up and towards you at the same time. Now you can run the wire behind the pillar easily and avoid the airbag stuff.
Next, remove the panel on the side of the air vent. I just used my finger nails and pryed it away. I tucked most of my excess wire in here and ran the rest of it down and around the bottom of the dash to the cigarette lighter. I didn't thread it through the hole here, but continued to run it on the outside and tucked the wire in the panel gap just above the fuel button.
From that opening I ran the wire down. There is a panel at the bottom of the dash that can just be pulled open. There are two metal clips that hold it on. I tucked the wire along that behind the metal clips and from there to the cigarette lighter. This panel doesn't need to be completely removed, Just the front to clips so you can tuck the wire up there. Also, make sure you don't block the OBD port thats around there.
Just put everything back together and you're done. When you put the pillar cover back on be careful to line up the blue fasteners with the holes. It's a little bit of a pain, but if you slide the bottom of the pillar cover back onto the dash correctly you should be able to gently feel your way back into the holes. I just tried to smash it on at first and broke a clip.
