If you investigate the motor a bit more you'll probably find one of the wires is providing a square wave pulse output that varies depending on the speed of the motor.

It should be fairly simple to build a circuit (i.e. 555 timer) to simulate this output and allowing you to dispense with your 'motor in a box'.
