    Hello, I need a socket diagram for a 3-pin Fiat because one cable does not go to the computer and it is probably damaged - no communication with the ECU. Someone help?

    removed immo should not affect communication, wires from the plug should go to the ECU

    just that one white and yellow goes to the cabin and when I found the same in the plug, there is no passage but I'm not sure if it's the same. it is best if I have a diagram or know which pin in the cube is from the k line of the l line someone will help? and if this white and yellow goes to the cabin, can I connect it immediately with ecu ??

    It is not possible to connect to the controller, even if you have everything unplugged, all you need is mass, plus and the K line, there you have EDC 15c7?

    Not all have L lines, it will work on the K line itself, it does not write on the controller but this is what I say, yes you can as long as the power, ground and K line were in the right place in OBD
