Help Mounting Prius C Backup Camera?

There is space in the left corner underside of the of the boot door handle, that's were reverse cameras are usually mounted. Guess you need to drill a in hole in the plastic handle and screw the camera in place. If you did not unscrew & remove the plastic ring that is on the camera (from your pic) before you wired it you will have to disconnect the wire to take it out.

That spot AQUA-K pointed out is the usual spot people mount their cameras, there's actually a plastic mould line where you can tell it's supposed to be. In that red C, a giant square was cut out, but you don't really need to make it that huge. A step drill should help you get the proper size circle you need.
These are <$10 at Harbor Freight or similar.

It looks like you'll have to make it a U shape cutout, with the top of the "U" facing the lic plate, in the rear handle to slide the camera into place then tighten. Doing it with the U shape will offer an alternate method vs having to remove the wire, mount, reattach the wire as AQUA-K mentioned.

 

Great idea djdawn this will save lot of trouble...

 

It looks like you already have the plastic washer on that camera. you need to twist it to remove it from the camera and then twist it back on from the inside of your car. You will disconnect the camera in order to do this. Unless that plastic washer is shaped like a C instead of O. the camera should be sit flushed onto your car, so that threaded rod should be skinny, not huge. Hope you know what I mean. I mean, do you see those grooves on that round thing? it's for you to easily turn that thing with grip.
