I have a 95 gmc sierra 2500 and im trying to put in my aftermarket rafio so i cut the stock harness out the square puece that goes in back of stock radio and now i cant figure out what wire is what i got...


I would suggest you spice the wires back to stock harness by male and female connections and tape over them with black tape then get a stereo install kit that includes a wiring harness ( cost about $20 maybe or less) for the year of truck you have... it will plug right to your stock harness ...never just cut stock stereo wires from stock plug it will be more of a headache than you think trust me I've installed all my own stereo system been there done that... good luck

Sorry i forgot to say i have a 1996 saturn so i need the stereo wiring color code of stock stereo to put in my new stereo


Buy a wiring kit from wal-mart or stereo shop. It will allow you to plug into stock wiring without cutting anything, and have instructions for hooking up your new system. Cheap and easy, plus you can go back to stock should you ever sell the car.

I have a toyota trueno 1992 and i want to put a new stereo in it


Go to the auto parts store and get a wire adaptor made for a 1992 trueno. It will plug into your factory harness. The wire colors are prematched to your sony and other aftermarket stereos. Just match the wire colors, splice with connectors making sure no wires are exposed. (A little electrical tape for good measure around splices helps). Then it just plugs in. If your factory stereo has mounts that screw onto the radio, unscrew them and attach them to the sony. Remove sleeve from radio and discard. The screw holes are already on the sony.

What does Park and dimmer mean for a jeep wragler car stereo?


If you are putting in a new stereo with all the pretty blinky lights, you will probably not use those wires. They are part of your interior lighting system (backlight for original radio.)

The white wire is the Park/marker Lamp Relay output signal. The Orange wire is the dimmer control signal (AKA "Illumination Control"). These both come from your Instrument Panel Cluster (IPC) module.

I cant get a stereo hooked up


Your question is not very specific but I expect that you have discovered that Volvo does not bother to color code their sound system wiring. They seem to use whatever wire they have laying around, so there is no particular pattern, and often all the wires are the same color.
If your car still has the original stereo plugs, you can buy a wiring kit from the installation shop at Best Buy. It will have a plug that plugs into the Volvo plug and wires that are color coded to standard color coding so you can figure out how to connect it to the new stereo. I not only had to put in a new stereo, but I had to bypass the original amplifier in my '91. The kit from Best Buy made it all Plug and Play!
