    Does it harm the computer if one of the terminals are left off the battery for any length of time.

    No it doesn't harm it. It will reset the ECU & erase any codes though.

    No, it won't hurt anything. Disconnecting the battery will actually keep any small draws like the clock etc from running the battery down if it has to sit for long periods of time, although any battery left sitting for long periods will eventually go flat even if it's disconnected.
