Your question is not very specific but I expect that you have discovered that Volvo does not bother to color code their sound system wiring. They seem to use whatever wire they have laying around, so there is no particular pattern, and often all the wires are the same color.
If your car still has the original stereo plugs, you can buy a wiring kit from the installation shop at Best Buy. It will have a plug that plugs into the Volvo plug and wires that are color coded to standard color coding so you can figure out how to connect it to the new stereo. I not only had to put in a new stereo, but I had to bypass the original amplifier in my '91. The kit from Best Buy made it all Plug and Play!

The stereo side of the wires should be labeled. Check out the12volt.com for a wiring schematic for the truck side. I advise against cutting and splicing wires for a stereo installation though. They make inexpensive harness adapters that will allow you to splice into the stereo harness without cutting into the factory wiring.

They are very easy to find online. Just google wiring diagram for the make and model.
