go to an autozone or advance auto parts store and find a haynes auto manual for your car. electrical diagrams are in back of the manual.

You could get a stereo installation kit for your year, make & model, that comes with a pigtail plug that would plug right into the existing harness plug and prevent you from having to hack up your original wiring harness.

If not....

Car Radio memory Constant 12v+ Wire: Orange
Car Radio Accessory Switched 12v+ Wire: The radio harness does not provide a switched power source. Run a wire to the fusebox for switched power.
Car Radio Ground Wire: Black/White
Car Radio Illumination Wire: Gray
Car Stereo Dimmer Wire: Brown
Car Stereo Antenna Trigger Wire: Pink
Car Stereo Amp Trigger Wire: N/A
Left Front Speaker Positive Wire (+): Tan
Left Front Speaker Negative Wire (-): Gray
Right Front Speaker Positive Wire (+): Light Green
Right Front Speaker Negative Wire (-): Dark Green
Left Rear Speaker Positive Wire (+): Brown
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Dark Blue
Right Rear Speaker Negative Wire (-): Light Blue

Good luck

The wires should be grey, orange and black, purple, and a black wire. The purple goes to purple, grey to gray. The orange and black goes to the small black wire on your car harness and the black goes to the bigger black.
