You may be lucky as far as the damadge goes. It sounds like the path of
distruction followed the grounds through the injector harness to the left
head grounding point. As others have suggested, open the burned harness back
to good wires and replace the burned. Leave the O2 sensor disconnected and
see what happens. As was explained in another reply, it sounds like the
current does not come through the ECM. My 84 has the single wire so I don't
know why it all happened.
May the force be with you!
