GOLF MK8 variant RVC retrofit

[blazpoglavc]

Hellou. i have retrofit reverse camera on my golf MK8 variant. I connect pin 6 orange and 7 gray wire. PIN 1 red wire power. I got error in VC and error on VCDS. Gateway doesnt comunicate with 6C modul and cant acces 6C. Im suspect at this pin plug. Any one now why gateway wont comunicate with modul 6C? is it sure problem with wire pin 6, 7 and 1? Please any advice be welcome...
I also plug white/green connector in gateway but i think this is OK.
