2004/2005 Nissan Maxima, Bose Stereo Wiring

Hey Guys, Im trying to add in a MTX RE-Q (basically just a fancy line out converter) to my 2004 Nissan Maxima with Bose - but I can not for the life of me track down a proper wiring diagram anywhere. There are two wiring harnesses/clips that go to the factory Bose amp, the larger one Im assuming is speaker inputs and outputs, while the other is just a power/ground/remote clip. What Im looking for is what each wire is on the larger connector - I need to basically know what wires are the amplified speaker wires actually going to the speakers so that I can tap into those for the LOC (Front L/R, Rear L/R, and sub needed). Any and all help is GREATLY appreciated!!!

Thanks you VERY much - I haven't had a chance to check this yet on my car but as soon as I do I will report back here as to whether the colors line up. Since you seem to be the only one anywhere that has access to the wiring diagrams for this car, would you be able to post the Amplifier Input as well - that way we can add this info to the "Vehicle Wiring" section of the12volt. Thanks again!
