Yes, i have seen that. But how can your interface communicate with k-line which is on pin7 on obd connector? The interface pinout (post #11) shows k-line on pin 1 (db-25 on interface). With your cable it goes to pin 8 (obd) and not to pin 7.

But the most strange thing is that your cable does not have pin 7 (obd) connected?

My question is: when connecting K-line (7 pin) 25db connector to pin 19 (Diagnostic module (OBD II) MB 38pin then will it be possible to do diagnostics of all units car?
