The 2 wires coming from the PCB that originally power the tail motor supply the variable voltage that the signal converter changes to a signal the ESC can use so you need both wires hooked up.
The power wire coming from the ESC supplies 5 volts that would normally be used to power a receiver and servos. That is the wire that should not be required. It is the red wire on the center pin.
I tryed that today....the tail ESC didn't function without that red wire from converter to ESC
