Have you tried to de-pot the old module? At this point I guess you don't care about damaging the components in it, you just what to extract the innards physically intact so you can see what is in there and hopefully reverse-engineer the circuit diagram.

I'd try heating it (at least to boiling water temperature) and if that doesn't work try a hold soldering iron on the compound and then common solvents. If all else fails, a burr in a Dremel tool can get into such things.
