Arduino Mega + Lynxmotion SSC-32 + Lego Power Functions Motors = Possible?

I'm working on a project that requires me to use Lego motors as well as Hi-Tec servos, and I already have the Lynxmotion SSC-32 Servo controller. So, I was wondering if anyone can tell me if it's possible for me to control the Lego Power Functions motors with the same setup.

Here is a link to details on the Lego Power Functions Motors:
Power Functions motors presentation (at the bottom there's a schematic under "Power Functions Working")

And here is a link to the SSC-32 specs:

The main issue I foresee is that the Lego motors have four wires, and the Hi-Tec have only 3. Any ideas?
