I cut one of the radio clips off, so now I need to know what color means what. I keep finding diagrams that say their for my car, but they are not the colors I have in my car, I have a Blue/white.
Blue/red
Grey
Grey/black
Yellow/red
Red
Orange
Yellow
Pink
Brown
Can anyone tell me what each color means? Please and thank you!

There is no gray wire with the standard system, so that tells me you have the Bose system with an amplifier.

Blue / white is switched 12 volts from the ignition switch to turn the radio on.
Blue / red is constant 12 volts for the station preset memory and clock.
The gray, and gray / black, wires goes to the amp, but the diagram does not say what their functions are.
Yellow / red is the turn-on signal for the power antenna.
The only red wire I see goes part way from the amp to the right rear speaker.
Orange and yellow wires go to the amp. I cannot say for sure, but if the circuits feed through the amp as the diagram suggests, these wires will go to the right door speaker after they leave the amp.
Pink and brown go to the amp, then appear to go to the left door speaker.
