To drive 4-pin bipolar motor you will need H-Bridge configuration ..

One of options is to use the L298 full-bridge driver and connect it as indicated in the L298's data sheet: http://www.learn-c.com/l298.pdf
( http://www.alltronics.com/download/1334.pdf )
Another option includes L293 + EDE1204 ( http://www.elabinc.com/ede1204.pdf )
.. Connection via NPN-PNP Transistor H-Bridge .. and so on ..
