- Remove Old Headlights: Unbolt the existing headlight assemblies. Carefully disconnect all electrical connectors from the back of the old headlights. Remove the old headlight units from the vehicle.
- Install New Headlights: Connect the wiring harness of the Morimoto XB LED Headlights to the vehicle's factory connectors. Ensure all connections are secure. Carefully position the new Morimoto XB LED Headlight Assemblies into the vehicle's headlight openings.
- Secure Headlights: Reinstall the mounting bolts to secure the new headlight assemblies. Do not overtighten.
- Reassemble Vehicle: Reinstall any removed grille, bumper cover, or fender liners.
- Reconnect Battery: Reconnect the negative terminal of the vehicle's battery.
- Initial Test: Turn on your vehicle's lights (DRL, low beam, high beam, turn signals) to ensure all functions are operating correctly.
- Aiming Adjustment: Proper headlight aiming is crucial for safety and compliance. The Morimoto XB LED Headlights feature both horizontal and vertical adjusters.
