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.

Hi, you can usually buy a stereo wiring harness that plugs right into your car and they are color coded to match the standard aftermarket wire radio harness, all you do is take the plug from your new stereo and match the wires with the adapter, just connect the matching wire colors. it's super easy and well worth the $15-20, and you don't have to cut up your factory harness.
good luck!

Www.modifiedlife.com has a resource page with factory wiring color codes

MAYBE FUSE BLOWN, TAKE IT TO NISSAN DEALER ASK FOR HELP.

what you need is to buy a wiring adapter for your car.it only cost about 15 bucks and plugs right in to your original plugs that were connected to your factory radio.the great thing about this adapter is that you dont hava to cut your original plug off just in case if you ever want to reinstall your original back.also the wires that go to your new headunit are color coded to match the exact colors that you connect to your stereo.you can't mess your connection up because all you have to do is connect each wire to the right color,tape them up,connect your stereo and you have music with all of your speakers working like they should and without any headaches.i hope this info helps.take care and good luck, manny

go to your local stereo shop or even wal-mart might have it but you can get a wiring pig tail that plugs into the factory plug in that wires to the new head unit to be installed and there is wiring directions in the packaging of the new pig tail.

you are a ******* idiot you+this answer= you are ******* stupid we don't want to know what our best bet is you damn inbred **** we want color codes!!!!! God you are dumb what color means what its like putting the caps back on the right markers in your coloring box with your little books that you cant even color inside the lines cause you are so stupid!!!!!!

Try radio shack, or stereo sales/installation place for ready to go plug adapter. For a few bucks, it saves headaches, and butchering the wiring in case you want to re-install old one later when trading in or selling the car.

Hey Larry did you ever figure this out? I am trying to find the answer as well....
