Was the old stereo you pulled out the original factory one, or was it
another after-market unit?

As late as '95 the always-on +12V for the stereo came from a 7.5A fuse
in the under-hood fuse box, same fuse as the ECU backup memory fuse. On
the factory stereo, this wire is only used to keep the memory and clock
alive when the ignition is off, it was never intended to actually power
the stereo. The problem is that most after-market stereos draw all their
operating current from the always-on wire and use the ignition switch
wire only as an indication that the ignition is turned on. If they kept
the same setup for '96 (new generation), I'd check in the under-hood
fuse box for a fuse marked "Backup", chances are it is blown (even with
this ECU backup fuse blown, the engine will run just fine).

If your '96 has the same always-on wiring as the '95 you should pull a
new wire from the under-dash fuse box to supply current to the stereo.
On the '95 fuse box there were 5 options connectors in a row above the
fuses, the leftmost one is always on and can be used for a stereo
system. Your '96 may or may not be similar.
