I've hardwired my Dash cam and radar detector to the fuse block. Just use an "add a fuse" and just test which fuses are activated when the car is started. I've done this to my 2013 Focus ST, my brothers 2017 Ford Edge Sport, and a friends 2017 GMC Terrain.I have purchase a dash cam went using cigarette lighter for my power, notice its always hot. I would like to have the dash cam come on only after car started. Any ideas how I can make this happen ?
