It's pretty unlikely that they are Molex as Yamaha would source locally or
make their own. I also don't recognize the blade configuration. If you
want to find the originals they will likely be from a Japanese
manufacturer.

For connectors with fewer than 10 pins you can sub a different connector
type even if the pin spacing is not exact for 2.5mm vs. 2.54mm pin
spacing. If the connectors are longer then the tolerances add up and this
won't work. You would need to change the wire ends too which is a pain.

A common and easy to use connector series is the Molex KK .1" (2.54mm).
You can get them with a gold or tin plated finish. They are about the the
easiest to crimp and insert. You can get them with keys and ramps which
prevent misalignment and lock the connectors in place
