The wires have been butchered really badly. I think so you will have to live with this desi method now.
The pinouts of this module aren't available online so it would be a really difficult task to rewire this control module.
But you can still adjust the vent temperature properly by using a thermometer and adjusting this desi thermostat to desired vent temperature.
I serviced the AC of my Cultus tommorow myself just got it properly vacuumed from a guy and did all the other stuff myself now the cooling is great don't know why but the vent temperature has dropped from 9.4 degree centigrade to 5.5 degree centigrade i didn't messed with the thermostat but now the cooling is really good... Still average during day time but at night it is chilling.
