The important selection criteria is whether a dual transistor multiplexer is evident on the input path of the blue wire, this sort of topology **must** exist, if the wire runs direct to the microprocessor, it is most likely incompatible, and probably an analogue voltage from a pot: The important selection criteria is whether a dual transistor multiplexer is evident on the input path of the blue wire, this sort of topology **must** exist, if the wire runs direct to the microprocessor, it is most likely incompatible, and probably an analogue voltage from a pot:
