Need help with audi a4 b7 2005 409.1 kkl usb cable wiring

[ebi_audi_b7_05]

Good day,

Please could someone assist me with a pcb and wiring schematic for 409.1 kkl usb diagnostic cable. Then I also have a Super VAG K+Can handheld device. For this I need the pinout schematic (from device pins to obd cable) as well. Many thanks.
