8A-82-0. That's the page in book 2 that indicates the green wire goes straight to the IP. So no, there is no fuse panel interface. And for that matter, it makes little sense that the green wire WOULD have a fuse on it.
Here it the schematic from the 1990 manual. Exactly as bogus described from the 1992 manual, so you're pretty much sure the 1991 is the same. Even the same page!
You may want to try looking from underneath. The harness that runs over the bell housing from driver to passenger side, branches off and runs behind the passenger head, down to the starter. The temp gage wire runs in this harness. It runs up the block, between the exhaust manifold and block to the sender.
Remember that heat may have discolored the wire, but you're looking for a disconnected wire with a female spade lug connector, so any discoloration should not be an issue.
If it was disconnected, it may have fallen below the exhaust manifold and can't be seen from above.
