Hey there.. Although I haven't ever decided to go Lucas's way, since i always picked Koogan, although the quest item for both is always the same. it resides behind a large radioactive goo pile in a container in one of the rooms left of Lucas, on the same map. Btw. Koogan wants the device as well, and probably wants to trade it to the same people (according to the later plot). EDIT: as for translation try to download a more recent version 1.3 or so from the radmurav team either from dropbox or from github, at least till now radmurav team recommends the dropbox verson.
