Hello, there was a website once regarding modification of a w168 to electric.
That site had some info regarding the w168 and obdii protocols. It seems the data in the earlier models floats between various pins and not only the pin 7.
This was the info:




Basically data passes through pins 1, 3, 7, 9, 11, 12, 13 and 15 and not just the pin 7 (k-line). Now I saw this mod for elm327 and FIAT ecu scan:

This guy uses some resistors to solder pins 1, 3, 7, 9, 12 to pin 7.
Could this mod work for the w168 soldering pins 1,3,7,9,11,12,13 and 15 to pin 7 with same type resistors? Can anyone try or suggest a solution?

This info regarding elm327 was on the benzev too:
