Please consider buying a radio wiring harness from Wal-Mart or any auto
parts store for around $10.  It connects to the factory plug so you don't
have to cut it off and wonder which wire is which, and provides a diagram of
how to connect its wiring to your aftermarket radio.  It also allows the
aftermarket radio to be removed and the stock one reinstalled very easily if
you sell the car in the future and want to keep your better radio.

You can find more info here, as well as instructions on the install process
overall: http://www.installdr.com/InstallDocs/Saturn/PDF/728005.pdf
