Install a backup camera on a yaris 2010?

Yes, it can be a bit of a juggling act to find something strong enough to push through, but flexible enough to get around all the bends. I used the thinnest wire coat hanger I could find. It would bend under the weight of anything heavier than a T Shirt. I guess that makes it about "Dry Cleaner" grade.

Straightened out, but with a rounded end so that it wouldn't dig in to any of the existing wiring, it was flexible enough to get around corners. Not "dead straight", a bit of a curve in the wire can help you get around corners. Once you get it through, you can use it to reasonbly gently pull the camera cable through. I made a small loop in the end of the coat hanger with a pair of pliers, sat the camera cable through the loop with a couple of centimeters cable free to the plug. That makes it easier to get the plug through.

When you get to the short flexible conduit between the hatch and car body, don't pull the end out of the car body. There is a plastic piece inside the car holding this in place. It is VERY hard to get this end of the conduit back in place.

Edit: Thinking about this some more, I seem to recall that I fed the coat hanger from the top of the hatch at the rubber conduit, across and down into the main part of the hatch, as I couldn't get through in the other direction.
