I tried searching, but couldn't find anything.

Just wondering if anyone could recommend an accessory wire to tap into for (+). I'm installing a front facing camera and a 2nd screen that will pop up from the dash and i certainly don't want them running when the car is off.

Thanks in advance.

 

What about using the rear view mirror? Many, myself included, use it to power radar detectors. There are relatively cheap kits that help tap the wires.
