Then disconnect the wiring harness that connects to the grille.
Step 4 - Remove Grille
Remove the grille from the vehicle by pulling it up and away.
Step 5 - Remove Plastic Cover
Next to the passenger side headlight, there is a plastic cover that needs to be removed. To remove the cover, use the plastic trim removal tool to remove the single plastic clip (circled in red below) holding it in place. Then pull the cover away from the vehicle and rotate it out of place.
Step 6 - Remove Bumper Clips
Using the plastic trim removal tool, remove the six plastic clips holding the bumper to the front of the vehicle. There are four in front of the radiator and one under each headlamp.
Step 7 - Remove Wheel Well Bolt and Clip
Moving to the passenger side front wheel well, use the 10mm socket to remove the 10mm bolt circled in red below. Then use the plastic trim removal tool to remove the plastic clip circled in blue below.
Step 8 - Loosen Trim Piece
With your left hand, grab the trim piece and pull it outward to create tension. Then reach your right behind the bumper in order to compress the two tabs holding the bumper to the trim piece.
Step 9 - Loosen the Bumper
Use the plastic trim removal tool to pop the tab (circled in red below) off of the bumper.
Then carefully pull outward on the bumper until it begins to separate from the vehicle.
Step 10 - Remove Side Headlight Bolt
With the bumper partially removed from the vehicle, remove the 10mm bolt (circled in red below) from the side of the factory headlight.
Step 11- Remove Top Headlight Bolts
Remove the two 10mm bolts (circled in red below) from the top of the factory headlight.
Step 12- Remove Factory Headlight
With the 10mm bolts removed, release the two tabs securing the headlight in place.
Then grab the headlight firmly and shift it towards the center of the vehicle to clear the lower tab (circled in blue) and remove the headlight from the vehicle.
Step 13 - Disconnect Factory Wiring Harnesses
With the factory headlight removed from the vehicle, disconnect the three factory wiring harnesses connected to the back of the headlight.
Step 14 - Transfer Factory Headlight Trim Piece
Using a Phillips head screwdriver, remove the two screws (circled in red below) holding the black trim piece onto the front of the factory headlight.
Then use the same two screws to secure the trim piece to your new Form Lighting LED Headlight as shown below.
Step 15 - Install Halogen Adapter Harness
If your Tacoma came equipped with factory LED headlights, skip this step and proceed to Step 16.
If your Tacoma came equipped with factory halogen headlights, you'll need to use the provided adapter. Simply plug the two adapter connectors (circled in red below) into the corresponding connectors on the back of your Form LED Headlight (circled in blue below).
Step 16 - Connect Form LED Headlight Wiring
Starting with the gray connector coming from the factory wiring harness, plug it into the corresponding connector on the Form LED Headlight.
Locate the smallest gray connector coming from the factory wiring harness and plug it into the sidemarker connector on the Form LED Headlight.
Take the yellow connector coming from the factory wiring harness and plug it into the high-beam connector on the Form LED Headlight.
Lastly, take the green connector coming from the factory wiring harness and plug it into the low-beam connector on the Form LED Headlight.
Step 17 - Slide Form LED Headlight in Place
With all of the wiring connected to the Form LED Headlight, slide the lamp into place on the Tacoma making sure that all three mounting points are aligned as shown below.
Step 18 - Test Function
With the Form LED Headlight in place, test for functionality.
Step 19 - Install Top Headlight Bolts
With the new Form LED Headlight functioning properly, install the top two 10mm bolts that were removed in Step 11.
Step 20 - Install Side Headlight Bolt
Install the 10mm bolt that was removed in Step 10 on the side of the Form LED Headlight.
Step 21 - Install Form LED Headlight on Driver's Side
Repeat Steps 5-20 to install the remaining Form LED Headlight onto the Driver's Side.
Step 22 - Aim Your Headlights
Using a phillips head screwdriver, tighten or loosen the integrated adjustment screws to properly aim your new headlights.

Step 23 - Reinstall Bumper and Grille
Once both Form LED Headlights are installed and aimed properly, reinstall the bumper and grille of the Tacoma by reversing Steps 1-4.
Step 24 - (Optional) Install DRL Fuse Tap Harness
Note: If you do not install the DRL Fuse Tap Harness, you will not have an independent daytime running light (DRL), as the C-light will only activate when you switch on your main beams.
Disconnect the brown wire (circled in red below) from the back of both Form LED Headlights.
Then plug in the connectors from the DRL Fuse Tap Harness.
Moving over to the fuse box, remove the cover and find the fuse puller (circled in red below) that is included from the factory.
Use the fuse puller to remove the blue 15 amp fuse (circled in red below).
Connect the DRL Fuse Tap Harness (circled in red) in place of the previously removed 15 amp fuse as shown below.
Then replace the cover on the fuse box and secure any excess wiring out of the way from any hot or moving parts.
