Hello I have a 2001 Grand Am that the factory wiring harness has been cut out. I am trying to install a Pioneer DEH-X6810BT. I can not figure out where some of the original wires need to be connected. I have figured out the speakers so far. I thought I had the power and the grounds right but the stereo is not powering up. This is the factory wiring schematics.

The wires I can not figure out are the 2 purple(class 2 serial data & gain control system), pink(radio on signal), light green(remote radio control signal), dark green(amplifier control), gray(instrument panel light supply 1) & brown(park lamp supply voltage) there were 2 grounds which I assume must be together.
This is the wiring colors for the stereo,
YELLOW = 12 Volts Constant +
RED = 12 Volts Ignition +
BLACK = Ground
BLUE / WHITE = AMP or Power Antenna On +
GRAY = Right Front +
GRAY / BLACK = Right Front -
WHITE = Left Front +
WHITE / Left Front -
VIOLET = Right Rear +
VIOLET / BLACK = Right Rear -
GREEN = Left Rear +
GREEN / BLACK = Left Rear -
Any help would be greatly appretiated
