| 8 | 8 | The connection to the main board is done through one 12pin and one 20pin connector. The connector is some kind of special ALPINA connector, at least I wasn't able to find such one anywhere. So, we will need them in order to connect our board with the button board. Here is an image, how this buttons do looks like (this image is taken from Bengt-Olof Swing, who works on a similar project, see [http://www.mp3car.com/vbulletin/hardware-development/139907-button-interface-bordmonitor-bmw-e39-e46.html here].) |
