Any time. ycharlie, sorry I missed your note asking for some photos of the wire run between 12V socket in the trunk and camera on the rear window. Here they are, don't know if they help much but that's how I did it...
1. Closeup of Blackvue camera, mounted smack in the center of the rear window's upper edge, lens pointing slightly downward to get a full view of the street and traffic behind me. You see the power cable on the side, tucked behind the camera body.
2. Camera body removed, the power cable is tucked under the plastic window trim behind the camera body.
3. Cable runs under plastic trim to near the driver's side corner of the window and "exits" the trim (note I made a little notch with a Dremel to avoid the wire from getting pinched and damaged between the two sharp edges of the plastic panels), crossing over from the liftgate window to under the rubber seal around the lift gate. The rubber seal can be removed and the wire routed under, then just press the seal back in its base.
4. I marked in yellow the "hidden" run of the power cable under the seal, around the door and all the way down to behind the side panel on the load space area, where the cable draws power from the 12V socket. If your hard wiring kit doesn't include it already - but it normally does - you should install a small inline fuse on the positive lead right here, before the camera power wire splices into the 12V lead of the socket.
