  1. I installed an aftermarket stereo for my daughter and her 2003 Chevy Malibu. Everything is been working fine but she notice she has no more cruise control, is there something I left out?

  2. Adam, first double check ALL your fuses and make sure ALL your fuses are good. You can do this by using an Automotive Fuse Tester and making sure all of your fuses are not blown. If all of your fuses are good, your 2003 Chevrolet Malibu may have a factory amp that needs to be turned on by your after market radio. The car radio amplifier trigger wire has to be wired up to turn on your factory amplifier to output sound from your speakers. Double check that your 2003 Chevrolet Malibu amp turn on wire is connected. Hope this helps. Good luck with your 2003 Chevrolet Malibu stereo installation.

  5. I just checked behind the radio and it appears that there are two orange wires coming from the ignition harness. Which one should I use to connect my accessory wire? I have a picture if it would help. Thanks again for your help.

  6. Ben, run a primary wire from the back of your radio to your steering column and use the orange wire in the ignition switch harness. This orange wire will provide a switched power source for your 2003 Chevrolet Malibu stereo. Hope this helps. Good luck with your 2003 Chevrolet Malibu stereo installation.

  7. I just wired up my 2003 Chevy Malibu for a Pioneer AVIC-D3. I used the wiring diagram to make sure that the the pins in the aftermarket harness matched up with the correct wires on the car harness. I’ve read several posts about adding a 12V accessory wire and running it to the fuse box. I’ve noticed several issues with trying to link the wire to the fuses on either the driver or passenger side. When I link it to a “10” fuse on the passenger side the unit turns on with the car but the car will not stay running when I start it. When I link the wire to any of the accessory fuses on the driver side the gas gauge does not work when the car is on or running but the car does stay on after it’s started. Does anybody know what I should do about this? I’m pretty sure everything is wired correctly. The illumination is working and the speakers are working no problem. I have grounded the unit with a screw in the chasis. Thanks for your help

  8. Tim, we suggest you get a car aux input adapter. This adapter will allow you to input any Apple iPod, mp3 player or portable music player into your factory stereo. This is the most cost effective and easiest way to add a car audio input into your factory radio. Here is the adapter you will need:

  10. I have a 2000 chevy Malibu with the original factory CD stereo and a separate but original “auxiliary external tape player”. I was trying to figure out what wires in the harness would be the audio so I could replace the “auxiliary external tape player” and use its wiring harness to hook up a jack for an ipod/Mp3 player. I can take a pic if u think it might help. Any ideas?
