Connect the main wires from the controller:
- Motor Cable: Connect the motor cable from the controller to your electric motor. This is typically a 9-pin connector.
- Cables de alimentación: Connect the red and black power cords to your 36V or 48V battery. Ensure correct polarity (red to positive, black to negative).
- 1-to-5 Cable: Connect the 9-pin end of the 1-to-5 cable to the corresponding port on the controller. This cable distributes connections to other accessories.
- Light Cord: Connect the red 2-pin light cord to the tail light.

4.2 Connecting Accessories via 1-to-5 Cable
The 1-to-5 cable simplifies the connection of multiple accessories. Connect the following components to the corresponding ports on the 1-to-5 cable:
- S810 Display: Connect the 5-pin display cable.
- Dial Accelerator (Throttle): Connect the 3-pin throttle cable.
- Palancas de freo: Connect the 3-pin electric brake cables from both brake levers.
- Luz: Connect the 2-pin light cable (if not directly connected to the controller).
