Installing and wiring reversing camera on number plate.

You need to wire the camera to the reverse light or the switch. Find the lights wire color, tap into it, and ground the ground the ground wire of your camera.

How I can route the wire inside the body, How can open the interior of the boot door.

take the tag off look for screws.do u have a hatch back?

It is a hatch back but I cannot see and tags or screws in the interior of the boot door.

The part I want to open is called the Plastic trim inside the boor door. The problem is that I cannot see any tags, screws or friction pins. Thanks for all your help.

If there are no screws, there will be push pin type anchoring system for the trunk liner. Carefully pull out. Fish the wire around the back seat, remove the rocker panels and run the wire with the cars harness.

Thank you, every one. I opened it. There are pins inside the panel, so you cannot see them. I just pulled it. To close it, I just need to press the panel on top of them
