Step 1: Using your Phillips screwdriver (with a flathead), gently turn and lift the retaining screw mechanism that holds the headlight assembly in place.
This is located near the outside of the assembly, under the hood, and on top of the headlight.
Step 2: With a firm tug, remove the parking light and disconnect the wiring harness.
Step 3: Loosen and remove the four 10mm retaining bolts that hold the headlight assembly in place.
Step 4: You can now pull the headlight assembly from the vehicle.
NOTE: If you purchased your new headlight from Go-Parts, it includes the bulbs, so you won't have to remove the bulbs from the old assembly!
Step 5: Disconnect the wiring harness from the headlight assembly.
Step 6: Connect the wiring harness to your new headlight assembly and move it into place.
Step 7: Secure the headlight by tightening the four 10mm mounting bolts.
Step 8: Reconnect the parking light's wiring harness and move it into place.
Step 9: Secure the parking light by reattaching the retaining bolt.
