Radio wiring diagram and color diagram needed?

The differences are due to there being 6 different stereos they used in those. There was the base unit that was just 4 speakers. Then there was the middle unit that had all the toys except the amp and better speakers. Then there were the 4 variants that had the higher end stereo with and without the Fosgate amp and with or without navigation. Which version do you have? Posting all 6 would get confusing as there was different wire colors used even if the functions were the same.
