Sources for JST EH Cables for your X10A port

[bashers222]

Personally i've been using dupont connectors without issues for three years now, but i see others are struggling to find proper cables as the JST EH is not too common on Amazon
There is another 2 project that link into Daikin AC units, similar to ESPAltherma but for cooling and those projects have create wiring kits that may be of use.
If you are interested search for Faikin or Fakout leads and you might find what you are looking for

Also, search for the Dakin part EKRS21 (S21 cable) which is a cheap premade lead you could cut and solder to your device if that suits
