Question E220/e320 Fault Codes

I have a UK spec E220 COUPE 1996 Last of the old 124s
Great car but getting info on the 111.960 engine is a problem. It has Bosch HFM injection SYSTEM and a 16 pin diagnostic socket. The following pins are present-1,6,8,10,12,16. I want to read the flash codes on the ECU. Could anyone out there tell me the exact pin identities so I can retreive the codes. The engine management system is probably the same as the U.S. c220 saloon of similar vintage. The diagnostic socket may be the same as the e320 coupe.The haynes diagnostic fault codes manual 3472 chapter 22 lists all the merc fault codes to about 1999,and how to extract them. . Trouble is my car falls between the later 32 socket OBD2 cars and the the good old bosch -jetronic EZL Ignition cars. The haynes manual also states that the ECU output pin on my 16 pin socket is pin3, but THERE IS NO PIN3 on my DIAGNOSTIC socket? Hence the question.

cheers Graeme
