Default help please-Radio wiring

I'm trying to fit the original 8 track player to my 1980,figured most of the wiring out just got a problem with the orange and brown wires(separate connector) if I put 12v on the orange wire it works ,what does the brown one do and should the current be switched or constant?

any help much appreciated

Do you have a multimeter?
Test the brown wire for voltage -Key off and then key on
If it doesnt have any voltage set your meter to Ohms and test it to see if its a ground.

Unless the old 8 track player has a clock or station memory (which I really doubt) it should have no reason for a constant voltage

It's OEM and it does have a clock & memory the brown wire comes out of the back of the set and is paired with the orange one.

These radios were not available in 79 so I wired mine up Myself
but I do have a wire that is hot all the time connected to the Orange
for memory. For the life of Me I cant tell what the brown is for. Does
everything work when You have orange hooked to hot wire,does
power ant. work? For some reason I think the brown is a ground but
just cant remember for sure. Sorry couldnt be of more help.

I've been looking at a wiring diagram and it appears the brown wire is a dimmer, does the Corvette use this function?The grey wire listed as illumination appears to have no effect,the orange wire provides lighting.

Perhaps the brown wire is switched w/the lights? When the dash lights come on the 12V would "signal" the radio to dim its display.

FWIW. Good Luck!
