Noop!! Actually if I had a look at connector orientation (its upside down) I would number the pins correctly. Problem solved

Hello, I come from Greece, I own C3/2003, 1.4 KFV engine, gasoline. Im building up a self made interface for communicating to ECU through OBD and I come to the following problem : The in car connector is pinned at 1, 5, 6,10,12, 13,15, 16. All other pins are not installed. Reading about the subject, it seems that no communication protocol is valid with only these pins OR my info about associated protocols are not correct. Has anybody a correct layout (pinout) of the OBD connector for specific model or can give an idea ? thank you
