My brother had to make one, its quite simple really.

Take a long pole and attach it to the flip part of the trap, and then attach a string on the end of the pole. Wrap the string around the axle of a set of a wheels.

As the trap flips, it will pull the string, spinning the axle and ultimately the tire making the car move.

The long rod just helps you get more movement since the mouse trap will only pull the string a couple inches without an extension.
