I think it was in the instructions. There are two communications busses. I think the medium speed bus is the one you want. Grey - Orange and Violet - Orange. Pins 3 and 11.
That is on my 2011.
Per 12V Guy: It's not medium speed you want. It's high speed pins 6 and 14. See the instructions for the colors.
