On the powercell/pack light board there is a blue block with two set screws. It is marked as "Pos" and "Gnd." You would need a stretch of wiring with bare ends on one side and preferably an adapter to connect to the blue brick otherwise you would have to cut off the male end of the battery. Not sure coming off the battery which wire would constitute the positive or the ground though. I am using a Spengler plate with wires (courtesy of NStevic01) to connect the brick to my Matty Blaster soundboard but the bare-wire hookup would be similar. http://www.gbfans.com/forum/viewtopic.php?f=31&t=35806
