- Open case at USB end of the cable gently with small screwdriver. Pry at the cable stress relief end.
- Watch this video (Yaesu FT-4X Programming Cable) and dig out the needed diode from your parts stock.
- solder it up

- Test the cable with programming software available at yaesu.com
- Reassemble the case
