I've no idea if there Is any difference In the looms, but if you have found the location of the issue (the fuse blows when you flex a specific point).
One of the cores has snapped inside its insulation, when the wire is wiggles the core arcs, creates a fault current and blows the fuse, you will not be able to see the exact point of breakage untill you remove the cores insulation.
why not just undo the tape around the wires, flex each wire individualy till the fuse blows (this is the faulty wire that needs replaced and rough area of the broken core) cut away the damaged section of abs wire and solder in a new section of wire, this will be a full perminant repair, would only need a short of length of wire, some heat shrink and insulation tape (to wrap the loom up again) . It's likely to be much cheaper than purchasing a new loom.
If your not confident is doing it ask a local workshop what they would charge, it isnt much of a job and the materials would only be a couple of £.
