I am new to this Smart car community. I really enjoy our Smart car and even more so because it is a convertable. I do have a question if some one can be of help. My engine light went on and it seem that it was caused by a lose spark plug wire. But I need to get the engine lght off. I am buying a code reader but first I need to know where the code connection is located and if it is a 16 hole plug an OBD2. Can anyone help me with this? Thank you, John
