Car stereo replacement gone haywire on 1993 subaru legacy

I replaced my old stereo because it broke, except maybe it wasn't the stereo that was broken. The new stereo works with the key on but loses all memory when key is off. I tested what I thought was the constant (not switched) wire and there is no juice when the key is off. And since I took the stereo out the dome and map lights don't work. Help!

Please don't say fuses, I've checked them all three times, and replaced almost all of them, just to be sure.
