Alright, well, that was a pain in the arse, but I just did a Viofo A129 Plus Duo with a hardwire kit this afternoon. I put the front one up near the top of the drivers side just far enough away from the instrument pod to have that out of view. Ran the wires for the hardwire and rear camera up into the headliner, then tucked them around the top corner near the drivers door, and pulled out the weatherstripping and ran them down inside that channel to the fuse box area. I didn't want to deal with trying to run them in the A pillar due to the airbag factor, and this actually worked great.
The rear camera cable I just tucked under the door sill trim all the way back to the rear seat , then went up along the side of the rear seat to get up to the rear camera. Due to the way that hatch is configured, it doesn't have a terrific view, but it's not too bad.
The biggest pain in the butt was getting the hardwire kit working. There's a grounding bolt way up inside next to the fuse box, but I couldn't easily get in there, so I ended up grounding to another nearby bolt. My biggest issue is that things just would not turn on, until I realized that the unused fuse slot I used for ACC (number 13) actually only powers on with the engine running, not with accessory power on. Once I started the car, it all turned on and worked as expected. I liked that I was able to use fuse slots that are not currently used by the car, so I'm sure I'm not interfering with things. They definitely give you plenty of extras!
Will let you know how things work once I try it out for a few days. Right now I'm testing out "parking mode" with it set to take a picture every second in a sort of time lapse, so we'll see how that works out. I also set the hardwire kit to power down at the highest voltage cutoff it had, because I care about the dash cam way less than I care about being able to start my car.
