Sorry for the lack of pictures but I have a dual cam as well, BlackVue. I ran mine from front to back with a small flat head screwdriver, a plastic wedge tool (not necessary but makes things easier), and a wire coat hanger like the ones you get from dry cleaners.
- Just run it from the driver side and run along the head liner
- to the A pillar
- to the head liner again
- then the B pillar
- rear seat head liner
* (use the coat hanger for the next steps)
- to the rear middle seat belt hole in head liner
- to the hole in the top rear rubber hose (pops off easy) that goes to the top of the trunk
- through the rubber hose to the wiring for the trunk lid
- and straight to the center of the rear glass
*note* if yours is similar to the one I have be extra cautious when plugging in the wires to the device. The pins can bend very easily and if forcefully pushed in the center pin will break. I had this happen in my previous car
