Electric Motor Jbeam

Question

I am trying to create an electric motor for the Bruckell LeGran in the game BeamNG.drive. For some reason, the code that I am using does not connect the motor to the rest of the drive train.

}
}

I have tried to use the Vivace electric motor as a base but that seems to make the motor active but still not connected to the rest of the drive train.
