INSTALLATION GUIDE

Required Tools :

  •  10mm Socket & Ratchet 
  •  Trim Removal Tool 
  •  Phillips Screwdriver 
  •  Wire Stripper/Crimp Tool



Part 1: Front Bumper Removal

Step 1: Remove Radiator Cover Clips
Open the hood. Use a trim removal tool to pop out all plastic push pins securing the upper radiator cover. Remove the cover to access the top bumper bolts.

Step 2: Remove Top Bumper Bolts
Using a 10mm socket or screwdriver, remove the bolts securing the top of the front grille and bumper.

Step 3: Remove Wheel Well Screws

In the wheel well, remove the screws securing the bumper edge to the fender liner. Repeat on both sides.

Step 4: Pull Bumper Off
Carefully pull the bumper corners outward to release them from the fender clips. Once free, lift the bumper off and set it aside on a soft surface to prevent scratches.

Part 2: Headlight Removal & Prep

Step 5: Remove Factory Headlight
Remove the four bolts securing the headlight assembly (10mm). Disconnect the wiring harness plugs and remove the factory headlight from the vehicle.

Step 6: Transfer Lower Bracket

Remove the black mounting bracket from the bottom of your OEM headlight. Install this bracket onto the new headlight assembly using the original screws. The light cannot be mounted without this.

Part 3: Wiring & Installation

Step 7: Connect Headlight
Connect the separate Red wire to a 12V ACC power source (fuse box) or battery positive. Connect the Black wire to a chassis ground bolt. This powers the demon eyes/DRL animation.

Step 8: Adapter for Touring Models

Use the included adapter harness to convert the factory plug to match the new headlight. If you have an older base model, this may not be needed.

Step 9: Install & Test

Plug in all connectors, including the demon eye wires. Bolt the headlight back onto the car. Turn on the ignition to test all functions (Low beam, High beam, DRL, Turn Signal) before reinstalling the bumper.

Step 10: Reassemble Bumper

Once testing is complete and all functions work properly, reinstall the front bumper in the reverse order of removal. Secure all clips and bolts.
