So that was my prep work last week.
Again, I made a smaller pilot hole and then enlarged the hole with subsequent larger drill bits taking time to test if the camera plug could wedge in there and then stop. With my trunk out, this was extremely easy to do. There is nothing on the other side of the rear bumper in that location so you won't drill into anything on the other side. You will want to verify before drilling though...
Then, I fed the camera plug through the rear bumper through the drilled hole and wet the grommet with some water and slipped in the grommet in the hole! Woohoo! looks stealth and stock.

This is what it looks like from the inside of the trunk compartment with the wire surrounded by the rubber grommet.

This is the amount of wire I have to route to the front of the cabin into the cabin through the rubber grommet in the passenger foot well. I will route the wire along the passenger side wheel well, under the intake airbox, along the side of the body under the door sill, out the passenger front wheel well, run it alongside the CF tub and wrap it around the front to the rubber grommet.
Because there is so little material and stuff for our car's weight reduction, there is a lot of room to route wires and zip tie to.
