Need constant power my Pioneer XM tuner

[frankthomas]

my presets keep getting erased so pioneer said my tuner needs to be hooked up to a constant power source. My question is how and where can i find a constant power source that I can splice into?
Also, should i worry about it draining my battery completely down if i dont use my car for 2 or 3 days? Anything I can do prevent that, like getting a bigger battery?

the yellow wire, should be hooked up to the ignition, where its constant, also behind the radio, the harness can supply the constant power, the yellow wire is where u tap, if u want, u can alway get the constant power from the battery, it doesnt drain nothing, it only works if u have it all hook up correctly, meanin yellow to the constant, red to the switch that is acc, also can be tap on the radio harness, and the black to chasi ground. also is it pioneer xm tuner box? pioneer uses those wire colors on there stuff alot, i know kuss i have all pioneer deck/screen, dvd changer installed, also ipod too.
