Hi @huxaifaahmed
If you don't get any more relevant answers try [https://www.brelco.com/en/contacts.html|contacting the manufacturer] and ask them if they have suppliers in your location or if they can provide you with more detailed specifications e.g. pinouts etc. Always worth asking.
Given the time of the year you may have to wait until after Christmas or even until after the New Year for a reply from them. I don't know.
