Educated guess on my part

If you have the factory radio, and all its connectors on the back are plugged in, then disregard what follows....

If you have an aftermarket radio, it may be an unused connector that would have plugged into the factory radio (memory function), and more probable if it measures 12V with the ignition off (and fuse 21 is OK).
