For a Pioneer CD car stereo, the memory wire is typically yellow. This wire is used to maintain the stereo's settings and stored information, such as radio presets, even when the ignition is turned off. It's important to connect it to a constant power source to ensure the memory functions correctly. Always refer to the specific manual for your model for accurate wiring information.

If you are using a wiring harness they are color coded. Otherwise, get a voltage tester to find the "hot" wire and the memory wire. you will have to trace the speaker wire.

There are for stereo wiring color codes. The red wire is the positive wire. The black wire is a ground wire. The green wire is the speaker wire. The white wire is the auxiliary wire.
the red is your main power wire, it makes the stereo turn on. The yellow is the memory and needs to be hooked to a constant or always hot lead, so you don't have to readjust your stereo every time you turn it on and off.
