On the 92 Mustang, you should only have a single black wire... and that would be a black/yellow wire that is for the acessory +12v switched.

The best way to install the radio is by evaluating the wires the radio needs - for example, it will have one or more +12V switched wires - connect those - however many there are - to that black/yellow wire. Don't rely on matching up colors - just be sure that you are matching up the wire functions. It will rarely be a one to one connection. It is possible to have wires on the car that are not used. It is also possible to have two or more wires from the radio connected to a single wire on the car. It just depends on what the head unit needs.
