PDC retrofit. Front sensors & harness part numbers?

[wide23]

Hello,

I would like to add park distance control system to my Polo 6R 2013.
I started digging. I know that on aliexpress and others sellers offer full kit PDC system but I want to check if I can collect all part myself.
As I know, I need:
Buzzer: 8E0 919 279
PDC module: 6R0 919 475 C
Rear sensors: 1S0 919 275 C
Sensor holders: 6R0 919 491 D and 6R0 919 491 E
Rear bumper sensors wiring: 6R0 971 065

As I think missed are:
1. Harness to connect PDC module with car – is it OE harness or custom? I found on carsystem.er but not in ETKA.
2. Harness between PDC module and rear bumper harness (Am I right?) – I found on carsystem.eu but not in ETKA
3. Front sensors and harness – I can’t even find diagram in ETKA with front bumper/sensors. Exist? (found on carsystem.eu). Or people using wiring and sensors from another car models? Polo 6C? Sensors: 1S0 919 275 or 1S0 919 275 C ?
4. Harness between front bumper harness and PDC module?

If I’m wrong, please let me know how it looks like with part numbers.

Best regards

the front and rear PDC bumper harness is almost the same, but the connector is in the middle a the rear and at the side, for the front setup.
perhaps you can use harness i.e. from mk6 golf?

all other harnesses must be made by yourself or from carsystems, i don't think VW has an OEM kit for it.
