Hey all, I did some searching and can't find a to-the-point post on getting a constant 12V feed that's easy to get to for a dashcam, so here it is.
Remove the front domelight / hazard switch / microphone housing using plastic trim removal tools, it can be tricky to get out, be patient. The grey facia is just a cover and the module is actually black plastic, be careful not to rip the grey cover off the module.
Once off, disconnect the black wiring connector, this is where you can find your constant power and ground reference.
- The yellow cable offers +13.4V when the car is awake and +9V when the car is asleep.
- The thick black wire third from the right in my image below is a ground reference. Be aware there is another thinner black wire on the connector that is not a ground reference.
You can then run the cable between the headliner and windscreen to your dashcam as seen in the second picture.
Things to note:
Since installing in December, I haven't noticed any battery drain on the main pack caused by the dashcam being constantly powered. As the Blackvue 650S I've installed goes into "parking mode" after a period of no motion, the camera draws little power, enough to use motion detection to start recording if something is picked up.
Make sure you check the specifications for your particular dashcam to ensure the operating voltages will work with the 13.4V to 9V range.
