Backup camera wire routing from number question

[Jasper7821]

I installed a double DIN radio and got a backup camera amd can’t figure how to run the cable from the license plate area to the tail light.
I also bought a wireless video kit so I don’t have to run the cable through the car.
I’ve searched and someone said you have to remove the spoiler, is there a way to route the cables without doing that?
I can either go through the license plate light or the round hole in the middle of the bumper behind the license plate frame.

I’ve looked for quite a while and can’t figure out where to run the cable.
Also read someone with a 2008 took out the taillight cover from the car, I did that too but there’s nowhere to run it. I have a 2001z

Any advice would be great.
