No ref at all on this that I know of. I lean towards it being the same as the PP2 pack. Or at least the same greeblies. No idea what order. The thing to remember is, all those "greeblies" did something. Find out what, and you'll have a much better guess. For instance, the gauntlet electronics connect to the batteries in the jet pack. I think thats the middle connector as seen on the PP2 pack. Its labeled "-wrist units"
So it stands to reason that was on all working packs.
