Here is another site with a factory wiring diagram

You need Adobe Reader to view the diagram though.

There is another way. You can use a volt meter and put it on the DC setting. When testing, use the red lead of the meter to test the wire and black needs to me attached to the black wire within the harness. Most common colors for your power are Red and Orange (switched power). Find the one with about 12.5 volts on it all the time (battery power wire). Label it as such. Then turn the key to acc and find the 12.5 volts on the that one. Label it as ACC. If have a power antenna you will need to hook it up. It is usually blue but you can leave it for now because process of elimination will leave an unused wire later on. Next, you will need to find your speaker wires once you have gotten the power wires out of the way. Take a battery, I would use one from a cordless drill. Use the battery to find your speakers by taking the wires that are common in color to each other, such as purple, purple/white and touch them to the + and - terminals of your battery. The speaker will make a noise and allow you to identify them. Go through all of them labeling the wires, there will of course be 2 per speaker. At this point you should be able to get it going again. Then hook up what you have identified to the pioneer radio. Hope this helps, any more questions just ask.
