In a wire harness, it is less than tens of ohms unless it is extremely long. Also, if there is no connection, the wire is open, and the resistance value will be extremely large. If the threshold value is between the short-circuit resistance and the open-circuit resistance, there is no inconvenience in the continuity test. "JIS C-3005: 2014 Rubber and plastic insulated wire test method 4.5 Continuity section" specifies as follows.
