Angry 2003 Deville Radio install - Help needed!

I have a 2003 Deville without the Bose package. I've exhausted all of the research available to me. My factory harness does not seem to match what I've found online. I'm installing a Pioneer AVH-X2800BS. The wiring harness from the car has the following color wires and pin location. Top 1.O 3.LY 5.Black 6.Purple 11.Clear tube 12. Purple/W 13. Blue/W 14.G 15.G/Black. The bottom: 4.R 5.Y 6.Purple 12.Tan 13.G 14.Clear tube 15.Clear Tube 16.Black/W. I understand from using a multimeter that the Top 1.O = constant 12v, Top 5.Black = Ground and that is all that is clear. The two purples Top 6 and Bottom 6 are constantly bouncing around the meter when ACC is on. I'm assuming the Top 12,13,14,15 and Bottom 12,13 are speaker wire because of the 3.98volts when in ACC. That's only 3 speakers. Any help would be greatly appreciated.
