Heater control unit change out.

Ok. managed to finally get a picture: Firstly at the fan motor resistor (pic1) . The way it's arranged is that if the power comes in though a BROWN wire, it goes through both resistors before going to the motor . If power comes in through the BLUE wire it goes through one resisitor before going to the motor and if it comes in through the orange wire it goes direct to the motor with no resistance (presumably that is HIGH setting for the fan). IF that is correct, what I REALLY need to know is where these three wires attach in terms of the three pins on the actual heater control switch junction (pic 2) and which one the power from the fuse box goes to? Of the three pins, two are in line with the movement of the switch and one is offset. The switch has an OFF , low and high setting.
