So, after witnessing a rather bizarre collision where the vehicle in front of me was struck even though they initially avoided the incoming vehicle I decided it is high time I stopped procrastinating and install a dash cam.
I have decided on a Blackvue 2ch with power magic ultra battery. Through my readings I'm familiar with the switched and constant 12v contacts in the fuse box but I would like the dash cam's battery to only charge when the vehicle is plugged in.
Does anyone know of a signal or connection for this purpose?
