i'v installed a wireless reverse camera and want to get power in the trunk instead of go through the car body

now i get energy on the licence plate light(in red circle), all the module and cable won't go out of the trunk cover, but the camera will only work when the light is on, it's inconvenience that i need to turn on the light on daytime when i need to use the camera

i've tried in other cable(green circle), they were not acc and always on, i think that's not safe
