Assembly instructions

1. Choose which side to mount the H3 controller.
   • The H3 controller can be mounted to either the right or left sides of the handlebar.
2. Place the rubber base around the handlebar, adjacent to the grip.
   • Position it in such a way that the H3 buttons are visible to the rider and the cable will be unobstructed.
     
3. Place the H3 controller on the rubber base.
4. Use the supplied rubber o-ring to secure the assembly.
5. Finalize by routing the cable through the frame, and connecting it to the main wire harness.

Careful not to over-tighten zip ties

Do not over-tighten zip ties, otherwise, you will risk damaging the controller’s cable.

Done

Your H3 3-button controller should now be assembled.
