Step 2: Loosen and remove the two 10mm bolts located on top of the headlight assembly.
Step 3: You can now pull the headlight assembly from the vehicle.
Step 4: Disconnect the wiring harnesses from the back of the headlight assembly.
NOTE: If you ordered your replacement headlight from Go-Parts, it likely includes new bulbs, as most of our models do. This saves you an installation step! However, if your particular model does not, simply transfer the bulbs and sockets to the new assembly. This process takes just a few moments! You may also need to transfer the wiring harness, though this is only for particular models. This is what the needle-nose pliers are for.
Step 5: Connect the wiring harness to the new headlight assembly.
Step 6: Mount the headlight by tightening the two 10mm retaining bolts.
