The part shows up in the electrical equipment sections of the parts books, which is where Triumph filed instrument cables alongside the rest of the electrics. Being NOS means it's original stock rather than a reproduction, so check the fittings and cable length against what's currently on the bike before you order.
If you're chasing an erratic or dead tach, a tired or kinked cable is one of the more common culprits, right alongside the drive gearbox itself. Worth a look before you start pulling the instrument apart.
