All US BRZ models that I've seen already have the reverse gear signal on the factory 28-pin harness.
If your camera is like most, the HU end of its long cable will end with a male RCA plug for the video output. It should also have power and ground leads, either near the camera, near the HU, or both.
Some cameras simply have an extra red wire embedded in the long video cable (with both ends exposed and not connected). It's the same as if you had taped an extra wire down the length of the RCA cable. It's available for you to optionally send the reverse signal from the trunk to the HU. You can usually also use that wire to send power from the HU back to the camera (and skip tapping into the reverse lights to power the camera).
In the Rydeens, the embedded red wire is already connected to the camera power lead near the camera.

Yup found out the hard way. For some reason I thought the HU is a pioneer. I had to return the harness and I'm waiting for the beatsonic harness.
