Maybe you asked the wrong question. I use a cheap plug that attaches to the vehicle and then makes the data available over WiFi. It works on EVERY vehicle. BMW, Prius, GM and so on.
The way the company solved the issue was to run all the pins into a microcontroller, the software then sorts out what kind of car is connected. So you may not need a full matrix switch but just a small uP and CANbus chips. Or just buy the gadget I have for about $20. It works well and I can even drive a car on the freeway while a person in the passenger seat looks at and record diagnostic data. (No I can't recommend a brand as they change day to day on Amazon.) It is a very simple device that acts as a CANbus/WiFi bridge. All the "smarts" lives inside the app on the iPad or phone.
