Disconnect the plug connections

Here you can see the plug connections that connect the display to the individual operating elements and the electronics in the scooter. Disconnect the appropriate plug connections of the affected element.
Detach all elements on the corresponding side of the handlebar so that you can route the cable neatly inside the handlebar again later.
Loosen the clamping screw on the handlebar

You will find a clamping screw on the underside of the handlebar. Loosen this to remove the control elements or the blinker from the handlebar.
Fitting new elements and insulating connections
Before you fit new elements, If necessary, prepare the shrink tubing and slide it over the plug connections.
Then reattach all elements to the handlebar and insulate the plug connections with shrink tubing or insulating tape.
Refit the handlebar and cover

Check the result
After reassembly, check that all controls are correctly seated and that the indicators are working properly. In particular, check that the cables are securely routed, the plug connections are secure and that they are firmly attached to the handlebars.
