I shut off my car and turn it back on i need to setup the radio and my settings again it doesnt save ! im missing the orange wire for illumination but my deck still illuminates its the memory thats doesnt...


Make sure the yellow wire is going to a source that still has 12v when the key is turned off. The yellow wire controls the memory and needs to be connected to a constant power source.

RCA connections go to external amp:

This is the basic layout for most all stereos. The ones that have an orange or orange/white, this is the illumination wire.
Good luck.

Pioneer deh-p3000 when i turn the key off and back on the stereo's doesnt remember anything


did you wire the radio yourself? it sounds like you have the yellow wire connected to a switched power source. the yellow wire needs to go to a power source which is always hot, or constant, whether the key is on or not.

DEH-5800Mp Button lights wont turn off when the ignition is off


Try installing a toggle switch to cut the power and the light may be on because you have the illumination wire hooked up.

Taking Pioneerdeh-16 cd player out of car


Like many stereos, this needed a set of slide in "extractors" to unlock the radio from the radio chassis. They are just short pieces of steel designed too push the metal slots back that lock the radio in. I just stuck a thin screwdriver back down the sides and bent the metal away from the radio so it would slide out.

After market radio connected to a 2003 Chevy Trailblazer


Hi,

The recommended wiring is that the yellow wire (from the Pioneer DEH-P3900MP) be connected to an "Always ON" B+12 such as the battery's positive terminal. Additionally, the red wire should be connected to a switched/accessory +12 such as the ACC terminal of the ignition switch. Wiring it this way would switch off the radio when key is likewise off.

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.
