The best way is you get a $7.95 harness conversion kit from Crutchfield with the radio, so you just plug them in, car plug to Alpine plug. Also, don't forget that many units are monitored and operated by the BCM although a 2003 is probably too old.
You can find a wiring diagram for an Alpine 7901 CD stereo online. You can search for the specific make and model of your stereo to find the diagram. Alternatively, you can contact the manufacturer of your stereo to request a diagram.
