DEH-P580MP I HAVE A PIONEER PREMIER.. AN NEED TO FIND MY MEMORY WIRE, AND WHERE TO HOOK IT UP.....

Hi,

If you are referring to the presets tuner station settings being deleted when powered off and or the clock resetting its time, then you have to verify that the Pioneer DEH-P580MP is wired as follows:
Black - chassis/body ground/GND
Yellow - always on/constant B+12 such as the + terminal of the battery;
Red - switched on B+12 such as the ACC of the IGN switch.

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.
