Sections of large connectors, such as those mounted under the dash, are connected together with a screw through the center of the connector.
To disconnect the connector with the retainer, use a small screwdriver to pry out the retainer (s), then disconnect the required connector section. Carefully inspect the connector, as connector latches are often invisible at first glance. Many connectors have multiple latches.
Attention! When disconnecting the connector, do not pull the connector sections in different directions by the wires, as the wires can be damaged or pulled out of the connector terminal clamps.
