have anyone follow the diagram and made a working one? I made one, but seems like there is no data going through the cable, the diagnostic port on 1G is white, and our car is black right? and the pin number on there is different also right? coz I have PIN 9, but in the pic, there is no pin 9, and I have pin 5 also, which I don't see in the pic on the site, I don't have a multimeter right now for some reason, so I can't really check what is up with the data on the port, so anyone got any idea? Thanks
