JST-EH connector does not fit on S21 on Emura 3 board

[migueldc73]

So, I bought the Faikin module, got it working, but can't seem to find a way to connect it to my S21 connector on an Emura 3
I bought a few JST-EH connectors based on the instructions

The S21 plug needed is JST, EH Female Connector Housing, 2.5mm Pitch, 5 Way, 1 Row, which needs pins and crimps as well.

The JST-EH is perfect for the Faikin side, but not for the S21 connector on the Emura board, which is clearly smaller than the JST-EH, with a pitch of probably 1.5 or 2mm.

As I can't find any EKRS21 cables in stock for shipping less than 4-5 weeks in Belgium/Netherlands, I am desperate to find the right connector model nr, so I can order it and make my own cable.
From another discussion thread I presume, it is the PAP-05V-S connector, but would like to have some re-assurance before I buy another set of useless connectors.

The S21 seams to be a "JST PAP-05V-S" connector, which are not very common.
I bought some ready made Chinese 2mm pitch JST cables and added 2,5 mm Dupont connectors for the Faikin side.
The Chinese 2mm JST are a little too thick but a little persuasion with a cutter knife made them fit. ;-)

As reference here is another thread about the cables: #260

It is a JST PAP-05V-S I ordered them and the crimp terminals from digikey and it fits perfectly.

I got this to work with an official Daikin EKRS21 adapter plus some F-F Dupont cables.

Reading now the HA forums, I have seen this cheap Aliexpress cable which I would try if I was starting again.
