Don't need that 2nd plug. Yellow I think is a mute wire possibly. And the other one is a vehicle speed sense wire. Some factory radios had a feature that would allow them to get louder as vehicle speed increases. Shouldn't need either one.

That's right, you don't,t use that plug.
 






On the concern of:

"BUT!! the radio does stay on when i turn the car off and take the key out (until i open the door) Im starting to read that this matter (please clarify for me)"

Your vehicle has accessory delay and will keep the stereo on for a prescribed amount of delay time. The delay is terminated once a door opens up. That is normal and expected.
 






Hi. I am currently doing the same thing by installing a performance audio, and soon to be video system in my 04. Here are the wires, and yes they are correct as this list has them.

I hope I helped!

Now to post my dome light question.
 






Thank you all! I went ahead and installed it color on color with the aftermarket harness. You all were right the second plug was no necessary. The kit I got from walmart did not fit too well tho. Wasnt too happy about that.
 






The stereo works fine and I'm actually impressed with the stock sound system, But when I drive it tends to come out but not fall out (not flush with the bezel anymore). I even screwed the support bracket on the unit and slide it on the metal peice inside where the stereo goes. Any suggestions ?? This is a pic of it

Did you happen to get the dimming feature to work. I still don't understand how to wire mine and it must be incorrect because it works incorrectly.
