check this web site for wire color info. it helped me on my 88 mustang. .http://www.stumbleupon.com/s/#1Pltxs/www.modifiedlife.com/car-stereo-wiring-diagrams-and-car-radio-wiring-diagrams// its free.

Check your grounds! If you used any "scotch-locks" wire connectors (the kind that crimp to an existing wire to hook up another) get rid of them. have had multiple customers with issues with thoes things. remember the basic electrical circuit needs both power and ground to opperate correctly. Good luck!

Check the bulbs, the fuse and flasher. If all else fails check the wiring.

I need to install a deh-1600 radio in achevy cavalier

You need an installation harness. You can get them at most anyplace that installs car stereos. Once you have the installation harness for your car, you just match up the colros of the wires on it to the same colors of the harness for the Pioneer. Make sure that each wire is insulated from anything by using some electrical tape and make sure they all have good connections. Strip away close to about an inch on each wire and then twist them together and then tape them good. After all the wires have been connected, all you need to do is plug the Pioneer harness into the Pioneer radio and then plug the installation harness into the factory wire harnees connector in the car. If you have any wires that do not match up in color, you can normally leave then not connected to anything, but make sure they are insulalted with electrical tape. Most all the wires should say what they are for. Matching the colors is the easiest way to do this.
Let me know if you need more help. I can always give you a detailed wiring of the Pioneer. I do not have the wiring diagrams for the car though.

If you have verified that indeed all the wires are connected as to where they are supposed to be connected, pls try:
1. Activating Internal Speaker to ON in the DFS Alarm Function'
2. the brown wire (or whatever color wire it is that is to be attached to a mobile phone) must not be connected to anything;
3. try all sources, AM, FM, CD;
4. check that none of the speaker wires is grounded.

Pls post back for any developments or the lack of it.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
