In the second episode of season 1 of The Sarah Connor Chronicle, a Terminator named Cromartie reassembles himself:
Another subplot is Cromartie's reassembling after he was supposedly destroyed in the previous episode by Sarah with an isotope-fueled weapon. His head falls out of the time displacement field and bounces on the grass. A highway worker finds it and keeps it for himself. Cromartie relocates his endo-skull and kills the highway man. He is later shown hiding among the homeless wearing a paintball mask.
So, supposing some other sensors compensate for the lack of eyes, how was his body able to search for his head if, as we saw in the episode 5 of season 1 , a Terminator could be deactivated by extracting the CPU from his head?
