Step-by-Step Repair Process

[00:49] Removing the Front Cap
Start by removing the front cap, which also serves as a secondary lock. Gently pry it off using a screwdriver. This step is crucial for accessing the pins within the connector.

[01:37] Releasing the Pin Catches
The catches that release each pin are positioned to the left and right sides of each cavity. Use a screwdriver to release both catches and pull the wire free with your other hand. This method ensures the pins are removed without causing damage.

Repeat the de-pin process for the other side of the connector. Consistency and care are key to ensuring each pin is handled properly.
