So, these wires are all original, as can be seen by the wear on them,
and the original solder joints. Since the disconnected lead can only
reach a few pins, I think that it may belong on PIN #11. I've been
suggested to try testing for continuity between PIN #11 and #12; no
continuity is what we hope to find, as this should be connected to the
Normally Closed (NC) terminal. Does this make sense?

The wire going to the transistor is the input for the receive pre-amp.
At least that's what it appears to be. So you are correct in it being
attached to a NC terminal per your schematic.

If you look at your schematic you'll see that there is one connection
between relay 1 and 2. Now look at your picture of
relay 1. You'll see Pin 11 contains a wire that runs to the relay 2,
and pin 4 of relay 1 contains a wire that runs to relay 2. One of
those pink wires (pin 4) is attached to a diode across the relay and
can be discounted as being part of your supplied schematic. So you
have one common connection between the two relays left, and that is
pin 11 of relay 1.

Attach the black wire to pin 11 of relay 1.
