Reverse Wire Location

[lion07]

Hello,

i know there a some threads for that topic but they dont give me the answer I need.


I drive an Mazda 3 2007 HB and I want to add a PDC to it.

My main problem is that I dont know where the reverse cable (orange/green) exactly is.

Is that behind that big side panel which I have to remove or can I get to it from that little Bulb Change Hole on the right side of the picture.

This panel I mean:

But if I have to remove that panel that Mazda Manual says I have to remove some other stuff. So i asked me if there another way to get access.
So i thought about removing this panel:

If I'm right the reverse wire (orange/green) goes through it and I have enough access to splice my power cable in it there.


And the second question. Did you guys route the wires for the PDC/Camera from the bumber through the grommit of the license plate lights?
