Thanks, that's the diagram I used to cable up in my 2012. It looks like they changed it for the shaker pro's in 2013/14. In that diagram the C290D/B connector pins 1 & 2 are the + and - and 4 is the mute circuit for the door sub amp. 5, 6 and 8 are the +, - and mute for the shaker amp. When I removed the head unit on my 14 that connector now only has a wire in pin 1 which is a 5volt feed I assume is for the mute on the door subs.

I searched every forum and googled my brains out trying to find it and all the online places like alldata only go upto 2012.
