Installation Notes and Tips

Verify the connector shape, cavity count, terminal gender, and harness length before installation. Match the vehicle application to the listed fitment, including any notes such as 6 cavity or JL4 active brake control where specified. Proper wire splicing and terminal crimping are important for a reliable repair, and the connector should be secured so the harness is not under tension.
