Octavia 3 reverse cam questions

I wonder if you would be kind enough to help a little? I own a 2016 vrs230.

I have bought a genuine Skoda camera (pic1) and intend to install it myself. I have a few questions about the connection that I would appreciate your input on before I go ahead and start the installation?

I have read the guide given by trust2k but he fits a non OEM item and mentions something about the differences in power supply

I'd like to connect mine as it would have been from factory

• I understand that this pair connect to the blue connector (pins 12 and 6). Is this blue connector found at the back of the Amundsen head unit or at the back of the module located in the glovebox?

• This brown wire is shorter than the red and the black and I assume it connects to somewhere in the tailgate lid - can you please advise where? (I have an electric tailgate)
  

The instructions state the brown should be +ve, is this correct? Where would you advise connection?

This black wire is shorter than the red wire but still long enough to reach the length of the vehicle. I understand this is to be connected to -ve. Where would you advise this connection?

This red wire is the longest of the three and I understand it is to be again connection to +ve. Again where would you suggest this is connected?

Finally - the coding.

I understand that for my head unit (Amundsen with bluetooth handsfree) that the coding is as follows:

Code byte 19 bit 4 in 5f to enable, and in 10 check rvc in 2nd or 3rd byte

I have been sent this by the supplier - is this correct for my headunit?

Many thanks guys
