Pinout Audi A4 EDC15? K and L Pins

[Phoeny]

Hy, I am looking for a pinout for the ecu from a Audi A4 1995 1.9 TDI AFN.

The best thing i found so far is this, https://i.imgur.com/y3HSRuT.png But it is missing the diagnostic port. To which pin does K & L conntect to? Also i have found i dont need L pin for communication?

ECU number is 028 906 021 FL

Thanks


Edit: k-line pin 61. L line is not populated.
