Those are actually coax cables, so careful stripping them.

You could also use a PC serial cable with a 9-pin male-male gender
changer...

With careful work and some soldering, that *could* be a permanent
solution, but I get your drift.

You can use a continuity tester to trace which wires are connected to
which pins.  All it takes is an AA battery, a 1-cell flashlight bulb,
and some wire.
