Installation Notes

Verify the plug clock position, pulley type, rotation direction, and amperage rating before installation. Confirm the vehicle is equipped with the original 135-amp charging setup and a serpentine belt drive. Compare the OE connector and pulley configuration to the removed unit to ensure proper fitment on the 2003-2004 Ford Expedition or 2003-2004 Lincoln Navigator.
