2006 V6 base radio to shaker 500 questions

I'm trying to upgrade the base radio in my 2006 with the Shaker 500 from a 2007. I have the amps and subwoofers wired in and working perfectly (Plug C290B). The main plug (C290D) is the exact same, so all that works. The only difference is plug C290A, or the middle one. I know five of the wires (Pins 3,6,7,8, and 14) are for the AUX input, and ping 15 and 16 are for the CAN system. I don't know, however, where pins 1,2,9 and 10 go. The only thing I have found is this image on Google, which says they are for stereo in L+ and -, as well as stereo in R+ and -. The wiring diagrams I have used so far don't have them on there, which is odd. Does anyone know where these wires go to? Any help would be appreciated.
