These models share the same QS-S4 communications protocol system which is also adopted on similar class VSETT models. Controllers are often branded Kyesang.

JST SM 6-pin Throttle/Display connector - Showing colours on communication cable, translated.
QS-S4 M8 5-pin connector pinouts as drawn observing the presented face of the display cable. Note colours on wire attached to QS-S4 may differ.
End-to-end colours: QS-S4 typical colour as viewed from face of M8 male plug (display cable as observed JST SM female, controller as observed JST SM male):
Yellow -ve
Green (green, green) Throttle | Black (black, black) Data +ve
White +ve (blue, - orange)
Blue PWR-ON (blue, orange) | Red (red, yellow) Data -ve

Image shows the colours across the pinouts on the JST receptacle from this display cable (left) and the matching colours on controller plug (right). It is observed that the colours chosen in this display cable (in all Zero's and VDM-10's) need be aligned / matched as shown below. The only pinout that has a colour match is the green (throttle).
