Unused features

Hi!

pontiac firebird 1988
radio: UT4? I think

I recently fixed the cable for my factory radio, however. On my radio I have 5 unused pins

and on the back of the radio I have some text explaining what the pins are used for. So my question is, are these features I can add + what do they mean

pic


11-15 are the pins I’m referring to

The backside
