Edubot and Main Controller

[MasterSnow]

Hi,

My team and I are trying to hook the main robot controller to the edubot. We have been successful so far, but the edubot servo motors do not respond to the joystick, even though we are recieveing a response from the controller through our OI. The system works with some other servos that we had. One thing we had to do was convert the 4 wire connection of the edubot servos to a 3 connection pwm cable so that they would plug in. Is the orange wire on the edubot servos important? It looks like it just runs to the battery, but this is the only conclusion we can come to. Anyone have any ideas on how to make this work?
