I assume you are referrring to USB pins. They are numbered 1,2,3,4. pins 2 and 3 are the TX/RX, 1and 4 are Vcc and GND
depending on the model of the airco, you will need to solder according to model 1 or 2
for Midea
For Haier and similar:
i hope this helps proceed
You have to guess which on is it or there are some recommendations to consider? Because it is hard to desolder these little pins if you've got it wrong.
