Dash cam hard wire install, no car tampering, automatically turn on/off with power button

I was installing a VIOFO A119 V3 Dash Cam on 2017 LT, but any Bolt with auto dimming mirror should work. The mirror has a switched power so the dash cam will turn on/off with the car.

The basic idea is probably similar to this post, but the pictures there are no longer available and it seemed to require splicing the wire. I found that you can just push a solid copper wire into the back of the connector without having to tamper with any existing wiring.

More details:

1) Take out the cover for the rear view mirror. Thanks to this post and this YouTube video, the process was fairly straightforward. You don’t need to take off the center piece.

2) Use a 12V->5V DC to DC converter (such as this one). Mine has stranded wires so I soldered a solid copper end to it. Stick the solid copper ends to the brown/black slot (positive) and green/white slot (negative). Wrap the exposed wires with heat shrink or electrical tape so that they don’t short out.

3) And zip tie it for strain relief.

4) Route the wires to the top of the cover so that the cover won’t pinch them. You can further hide the DC converter, but for me the end result looks like
