This PCB is the new version with the throttle connect to the PCB into the wire harness. (NOT DIRECTLY PLUG IN THE PCB )
Note that Mercane did change the production line in april 2019. the connectors from PCB to throttle inside the top case. If your WideWheel was been produced after April 2019, this is the right PCB for you.
If your WideWheel was made before april 2019 you will need to buy a new throttle as well HERE , or change the connector.
If you are unsure, open the top case and check if the throttle plugs directly onto the board (pre April 2019) or if the throttle connects to the board via a separate connector along the cable line (as of April 2019).
Easy to install inside the dashboard (with main button) of your WideWheel 2019
