Glad you got it fixed and it wasn't a bigger and expensive problem. (DOH! I completely forgot to look at my service manual yesterday.) You've learned electronics rule number one: It's usually the last thing somebody messed with!
Probably the fuse box shape and SOME of the fuses are the same. Obviously different models have different electrical circuits and fuses but the layout is usually close. The "clock" fuse will be constantly powered so the clock keeps time when the key is off. Probably, that same 12VDC is needed to keep the radio stations memory the AUX USB selection, and individual audio settings stored. Must also be something beyond those needs to operate the radio. The ACC/Audio fuse is keyed through the ACC relay.
