k-line on mercedes 38 pin

[xbyte]

I cant really understand what is the k-line pin of the 38 pins mercedes plug, i found this Mercedes 38 pin diagnostic connector pinout and wiring @ pinoutsguide.com


is it pin 4 or 7 ?

every controll module in the car has it own diagnostic connection at the 38 pin connector.
A diagnosis tool with multiplex capabilities switches between those conections.
So there will not be just one k line for diagnosis.
