OEM Reverse Camera Cable Connections in 2012 Tiguan - RNS510 Head Unit

[Kanga]

Ahoy V Dubbers,
Reaching out from Inverloch, Victoria.
Recently purchased 2012 Tiguan and installing "high-line" reverse camera (looks to be OEM equivalent, purchased on ebay: RCD510 RNS510 RGB Rear View Camera + Cable + Reversing Image Box For VW Tiguan 665752083680 | eBay ) to connect into the RNS510 head unit.
Confident that I have the backend of things sorted, including tailgate handle camera, control module and cable routing to driver's side dash.
Can't seem to find instructions anywhere online to show exactly where cables connect at the front end.
The 26-pin connector is obvious (back of head unit), but wondering if anybody can comment on the remaining 2-pin plug and 3x single cables as per image below.
Cheers,
Kanga
