well, as dan said, we used some CAT-5 cable, because it's easy to handle when it's all together (twisted, sheathed, etc), and then our electrical engineer went "dumpster diving" and found a huge 25-pin cable of 24 awg wire. we took the wires out of that, and used those, since they were all in a bundle, and once again, easier to handle. and yes, colors and much prettier
