I think the other wires are to do with determining pad thickness(wear).
When I stripped my calliper down to refurbish, I didn't see any other way that the car can determine pad thickness other than how far the motor mechanism moves in relation to the pad thickness that you are supposed to program in via vcds on installing the new pads.
