Connect 39k3 powerpack to 417j3 motor I'm new to lego.  Trying to connect the powerpack 39k3 from 42009 Crane to a 417j3 motor.  Is a 8528 Converter Cables for Mindstorms NXT the right cable?  

Is there a way to hack a phone connector onto a power cable?  Where would I find the wiring diagram?

Many thanks,

Joe
