Final answer:
The indicating band on the solderless connector insertion tool determines the polarity of the connector.
Step-by-step explanation:
The indicating band on the working end of the solderless connector insertion tool determines the polarity of the connector.
Polarity refers to the positive (+) and negative (-) terminals of a connector. The indicating band on the tool helps align the connector correctly, ensuring that the positive and negative terminals are in the correct positions.
For example, if the indicating band is blue, it may indicate that the blue wire should be connected to the positive terminal of the connector.
