To protect against water ingress, connector terminals that will not be wired require seal plugs (Molex® part number: 343450001) to be fitted.

• Ensure seal plugs are fitted and trimmed before wiring the connector terminals.

1. If required, insert a small flat blade screwdriver into the pry point and using the connector housing as a pivot point, pry out the connector insert, known as the TPA (Terminal Position Assurance), until it reaches the pre-lock position.
2. Ensuring correct orientation, insert the seal plug into the rear face of the connector.
3. Pull back on the seal plug to ensure it has locked into place.
4. Trim the end of the seal plug, protruding from the back of the connector.
5. Repeat steps 2 to 4 for each terminal that will not be wired.
