93 TURBO WAGON RADIO POWER QUESTION

[Subi81]

Is the Yellow/Red wire in both stereo connectors at the stereo, supposed to be on all the time?

My research shows that the Yellow/Red wire on both radio plugs is typically an ignition switched power source, but on my 93 turbo wagon it's always on  I can't remember if the previous owner kept or I removed the stereo.  The only other switchable source near the radio area is a little brown plug that I can't figure out what it goes to, maybe a CD changer.  Sorry not a radio guy and it's frig 118°F outside.

I haven't traced wires yet that is my next step unless someone on here with more radio experience than me can chime in and tell me that something is in fact wrong here then I can diagnose it.

This is all for a aux dash cluster project btw.

One wire will always be hot as it is the "memory" wire otherwise you would lose all the presets everytime the car is shut off.
