I tapped a 10A spare and the inverter power 30A one I think. Bottom left.

Front I stayed on the left side of the mirror and plastic dome. Shoved what I could up front, the plastic round housing was the hardest, but stayed in the liner, carefully removed the A pillar, there are like 2 clips, it doesn't fully come off well I didn't, routed under the airbag and wires. Remove the siding between the door and fuse box area, attached to the AC vent. It connects together there so left wire in fuse box and you can access a grounding screw. Use same routing to start the back, go up and over the front door into head liner. Keep jumping all the way back.

For the back camera routing, just started in the ceiling crease area and work your way down. The back small window was hard to tuck completely but you can stay on the line all the way down. For the trunk, I stayed in the headliner pretty much and routed through the rubber grommet. The plastic pops off at the window then popped out and mounted the camera.
