Wiring Function of Controller
DKD LCD Speedometer with Standard CAN-BUS
- It displays D, N, R, P, S gear, and battery current X5/10.
P.S.: If the working battery doesn’t have CAN-BUS communication, then the CAN-BUS speedometer will always be showing lack of electricity.
So, we suggest to do the speedometer as Line communication version if you can’t get CAN-BUS battery.
Z6 Throttle with Combination Switch
With Reverse, Parking button (Throttle on/off), 3 slide switch gear, S/boost button, Light and Horn.
It matches with Votol controller.
