Installation Notes and Tips

Verify the vehicle year, make, model, and HVAC configuration before installation. Several listings require manual AC, dual-zone temperature control, or automatic temperature control exclusions, so match the notes in the fitment table exactly. Confirm terminal orientation, wire color/function, and connector style before cutting or splicing into the harness.
