Adding Pins in the Expansion Connector

To insert additional Wires, remove the Black lock first, then insert the terminal so it clicks.

Use a small pick or screwdriver to push the Black lock back

You may need to release it from the top and bottom of the connector

When the lock is removed, it will stick out but not come out of the connector all the way

Once the lock is moved, insert the terminal and listen for an audible click

Wire fully inserted

Push the lock back into the housing

Depin a Terminal from the Connector

Follow the steps above to remove lock.

You will need something like our depin tool kit to do this.

Depinning Tool Set

Use a depin tool to push down the tab to release the wire out of the back of the connector
