There is a wiring schema in take that photo to too, also include model label. And your bottom and top side of the IR remote. This may be not Daikin base AC, recently in Thailand, Panasonic start selling Midea AC under their name too. If you have their original module, Try to buy cheap logic analyzer and learn how to hack it, Remember to note that most logic analyzer can only using 3.3V signal only, you will need level shifter to using 5v signal. If you are lucky, it is some of Chinese OEM AC like AUX, MIDEA, TCL, GREE and someone share it already.
