Not knowing the model I can't confirm exactly what functions these pins serve for sure but I can say that on other 6-pin connectors like the one with the # ACDOM135B pin 1 is the Compressor Hot and pin 4 is the Low Fan. I've attached a diagram below listing the pins by number and function. Since this unit is a replacement for a Dometic it's safe to assume the functions are the same but you could always doublecheck by calling Dometic with your model number and they could tell you exactly what the functions are.
