How to Install an A118 Dashcam in a Tesla Model S (Switched power with no wire splicing required) I always wanted to get a dashcam in my car but was originally waiting until next year when more funds freed up. Sadly that plan changed when a lady failed to yield on red, hit my car when I had the green arrow, and lied to her insurance to create a my word against hers situation. A dashcam could have helped me then so I went to look for a lower cost option compared to the Blackvue dashcam system a lot of members on the forum have talked about. I wanted a system that was easily removable and for now only on when the car is on.

I plugged it into the car can had it recording for a few days to make sure it behaved as I expected. Scrape off the adhesive on the wire clips provided with the A118 dashcam then wipe down the remaining area with rubbing alcohol. It's white and looks extremely obvious when placed on your windshield Add two Scotch mini tabs to each wire clip and trim off any area that overhangs Use rubbing alcohol to clean the area on the windshield underneath the rear view mirror that the dashcam will be placed. Also clean the area on the windshield where the wires will be run closest to the headliner from the dashcam to the driver side A-pillar. Allow a few minutes for the rubbing alcohol to be fully dried. Use rubbing alcohol to clean the part on the dash cam that will be placed on the windshield, apply the 3M adhesive to the dashcam, and place the dsahcam on the desired location in the windshield. I gave myself a little gap between the dashcam and the rear view camera. The dashcam is located out of my line of sight while driving. Place two wire clips just to the left of the rear view mirror by the top of the headliner and another wire clip to the right of the A pillar [INSERT picture] Connect the USB mini adapter to the wire and connect to the dashcam Run the wires along the windshield by placing them in the wire clips Open the driver side door and pop off the dash trim piece that is hidden by the door when it's closed. 3 clips hold this trim piece on and there is a wire attached to it so keep you're Hercules strength at bay when pulling the trim off. Place the trim piece on the floor. Pop off the trim piece just to the left of the trim piece that was just removed Pull back the rubber seal back slightly next to the top of the A pillar and tuck the wire in the closest opening to the A pillar all the way down to the bottom of the A-pillar [INSERT picture] Slide the USB A end of the wire into the gap leading to the foot-well. I used my finger to see where the gap is Use the zip ties to secure the wires to the trim piece just above the pedals Run the rest of the wiring behind the accelerator pedal and underneath your floor mat then to the USB car charger. Plug in the dash cam Reinstall the removed trim pieces [INSERT picture of final install from outside] Hopefully this helps some people. The USB ports for the Model S supplies enough power for the A118 dash cam so once I get an adapter that can prevent the use of the data protocols for the USB this setup can easily be changed from being switched to continuous by just plugging the wire to the USB port, as opposed to the USB car charger.
