Tacoma LED Grille Lights Step by Step Installation
1. Open your Tacoma's hood to gain access to the area behind the grille for the LED installation. 2. Lay out the wiring harness behind the grille - each LED bracket is designed to fit in their specific slots - as shown Left to Right in the image above. Start with the passenger side LED, separating the LED from the bracket and mounting hardware so that the LED and Bracket can be passed through the grille from the back. 3. Secure the LEDs with the bolt and mounting hardware from the backside of the grille. Repeat this step for all three LEDs - from Passenger side to Drive Side. 4. Locate the ground terminal on the apron. It is a 10mm bolt. Follow the wire from the negative terminal on the battery to the 10mm ground bolt on the apron. With the negative terminal on the battery disconnected (optional), remove the bolt to add your harnesses' ground terminal (circular end). Re-tighten the ground terminal to the apron. 5. Once your LED lights are secure to your grille you’ll want to run your wiring harness along the driver side fender and battery leading the harness to the fuse box. Secure the harness along the way using the provided Zip Ties. Note: some variations of our harnesses may be secured at points other than the one pictured below. Do not attempt to stretch the harness to reach any mounting point as it may compromise the strength of the connections. 6. The green single wire in this picture is used to show where the power will enter the fuse box. The power wire does not need to be pushed into the fuse box slot as shown here if you cut a small slot for the wire on the fuse box cover. We do not recommend cutting the fuse box bottom half for the passage. If you cut the lid only, you can replace the lid easily in the future, should you wish to remove the grille light harness. Please see the next picture for the "Add-A-Fuse" location - there are a few different installation locations for the Add-A-Fuse depending on your vehicle and options. Your fuse box may look different than the photo below.
7. Remove the Red 10 Amp INJ fuse or and insert the Add-A-Fuse in its place.
Route the grille LED lights power wire inside the fuse box such that there is some slack on the wire and pass it through the slot you made into the fuse box cover. Install the fuse box lid securely.
If you'd like to install the LED's so that they only turn on when the headlights are on, you can use slot H-LP LH-LO 10 Amp.
Please note: Due to the large number of variations of the underhood fuse box design, the proper Fuse may be located somewhere different than the photos referenced. Depending on the model of your vehicle we will be posting pictures and directions for all variations as we get feedback.
Test the installation by turning your vehicle power on. The lights are on when the car has its ignition switch turned on.
For your reference, the fuses on the Add-A-Fuse are as follows: The lower fuse, closer to the fuse box, replaces the original INJ fuse. The upper fuse is for the LED lights.
