Despair in Argentina

Hello, after having read a lot here in the last few days, I hope you can help me. I bought a Saab 9000 cde, BJ 93, Motor 234L, turbo, automatic, in the hope that the local mechanics would not have puffed around too much in it. Hope trog, could pick up a friend in Buenos Aires, but again at home in Mendoza the car did not want to. As it turns out, they have “replaced” the whole ignition system, I now need the ignition cassette and the ignition coil, in the hope that I will run the car again. I would have already ordered the Internet, but I am missing the key numbers and I am absolutely lay. Is now the red or black casette in, what must I keep in mind? Hope you will remember something. Thanks already in advance Yvonne
