Great post, thanks!
Do you think it's possible to get power for dash cam from the same spot under the overhead console?
FiSh The 12V power that feeds interior LED "mood lighting" (accessible from overhead console) also feeds the dome lights. It's been a while since I looked at the wiring diagram so I don't remember which wire exactly but if you unplug the wires going to the mood lighting control one of them is a 12V supply. You can find it fairly easily by probing the wires with a meter as only one wire will have voltage. It is the same 12V circuit that feeds the 12V cigarette plugs or for that matter most everything 12v in the car. Mine shuts off about 13 minutes after I leave the car. Some have mentioned that this circuit stays on up to 30 minutes but mine has never varied from 13 minutes. This circuit becomes active and the 13 min timer restarts when you do anything to "wake up" the car, open door, use key fob, remote start, go times. I wired the 5V power supply for my dash cam to this wire and used a screw for the overhead console as a ground. So now I have a little extra video before I start the car and after I walk away from it. The only minor annoyance is that it overwrites oldest video files sooner than I would like as it keeps recording after I turn the car off or whenever I do something to "wake up" the car like opening a door to grab something I forgot to take in. With a 32GB card I usually have 2-3 days before a video file gets overwritten so not too big of a deal.
