Terminal Installation Procedure
WARNING: This page is about a different car, the 2020 Cadillac CT4. However, it is still accessible from the selected car via links, so may be relevant.
Align the terminal to the connector properly using the figures above.
Once terminal is properly aligned, fully insert the terminal straight into the cavity until an audible click is heard or felt when the terminal is fully inserted. Gently pull on wire to verify it is fully seated.
Reinstall the TPA and push it towards the connector body until it is fully seated to lock and secure the terminal. This should require very little effort, if excessive effort is needed, reinspect terminal is position correctly, fully seated and the terminal lock is fully engaged.
