① Unscrew the screws and remove the plastic cover, or plastic „cap“, on the other side than the sprocket is located. Bikes without the separated plastic „cap“ in the bottom part will require removing of the pedal arm using a proper equipment. Needed cables and connectors are hidden under this cover.
② Disconnect the 5-position connector in between the display unit and motor unit and the 2-position connector in between the tacho sensor and the motor unit.
③ Connect both appropriate connectors from the MSO instead of the original connectors into the the motor unit and, firmly press the original, previously disconnected connectors into the MSO according to the color coding (red wire side onto the red/orange wire side, or down-facing at the motor body).
④ To keep the system waterproof, it is reccomended to use the heat shrinkable tubing on the both MSO connectors connected into the original connectors from the tacho sensor and display unit. Optionally, use glue gun to secure the connectors in the motor body. Place the MSO in a proper position and optionally, fasten the wiring using the electrical ties. Re-attach the plastic cover and pedal arm and the bike is ready to go.
