Unless mechanically broken your original foot controller can usually be cleaned and adjusted to work correctly.
I don't bother with the cloth covered wire. I use normal 18-2 wire with either SPT-1 and SPT-2 insulation. Depends on the machine and parts I'm rewiring. Works good and is not overly expensive.
