If you have the conector that fit in the reciver ..the smal white one like on my link..you can conect that direktly to the sourch you want a read out from ..I have no other than a cabel direct from the uregulated side off the digiswicths to the rx..I think it only a diode to prevent you from conect wrong polarity.
You must have the conector from your Futaba sensor try to conect on the sourch directly
