   3. 

      Connect a positive (+) lead from the batteries to terminal 6 (IND1) or 7 (IND2), and a negative (-) lead to terminal 9 (GND3) of the map light assembly connector.

   4. Check if the illumination for the emergency call switch comes on.

      OK
      The red indicator light on the emergency call switch comes on when the positive (+) lead from the batteries is connected to terminal 6 (IND1) and the negative (-) lead is connected to terminal 9 (GND3).
      The green indicator light on the emergency call switch comes on when the positive (+) lead from the batteries is connected to terminal 7 (IND2) and the negative (-) lead is connected to terminal 9 (GND3).

      Result
