For the earlier builds, there is a 12v power supply up under the screen where the microphones are. Any idea what plug would mate with that 12v plug to make taping in a bit easier?
It's actually not really hard to pop open the connector, then lay your prepared red & white wires (tinned & trimmed to length) on top of the hot and ground, then just snap the connector closed. Saves searching for a connector, and preserves the connector for the lighted vanity mirrors on the sun visors.... This is what I did when installing my Blackvue dash cam. You might search these forums for dash cam installs and the like to see what others have done.
