Step 7: Test It
Don’t connect the iPod yet. After all the cabling is attached, reconnect the car battery. First test the car stereo to be sure it works the same as it did before. Then attach an iPod and try the stereo’s auxiliary input. If everything works properly, the iPod should say it’s charging, and the music should be as clear as a CD recording of angels. Or Metallica.

There. That wasn't so hard, was it?
Step 8: Permanently Mount Everything
Disconnect the iPod. Temporarily disconnect the car battery again. Use cable ties to neaten up the stereo wiring - especially the 12-volt connections because you don’t want the power adapter to get jostled. Carefully position the new cabling and 12-volt plug behind the dashboard, and reattach the stereo. Finally, reconnect the car battery again.

Done.
