Tundra LED Grille Lights Step by Step Installation
1. For this installation, we will need to remove the Tundra grill from your vehicle. For more information on this step - please reference this YouTube video. Please use caution when removing your grille. Once the grille has been removed lay it on a table with a soft blanket or towel to prevent scratches.
2. Lay out the wiring harness behind the grille - the brackets are universal and can fit with whatever spacing you prefer.
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 grill. Repeat this step for all three LEDs - from Passenger side to Drive Side. Please do not overtighten the LED and washer to prevent causing damage to your grille.
4. Use zip ties to secure the harness wire to the grill in the small slots of the grille support beams. This will keep the harness from sagging behind the grille and out of sight.
5. Now with the LEDs and the brackets in place, place your grille back in line with the mounts. Run the harness towards the driver side of the vehicle - where you will find the ground terminal and fuse box. You can now use 1 or 2 bolts to keep your grill in place while you finish the installation.
6. 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.
7. Now to power your Lights, run the wiring harness along the driver side fender and battery leading the Add-a-Fuse of the harness to the fuse box.
Note: Do not attempt to stretch the harness to reach any mounting point as it may compromise the strength of the connections.
8. The photo below 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 use a round file to make 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.
There are a few different installation locations for the Add-A-Fuse depending on your vehicle and options. Please be sure to reference the lid of your Fuse Box for the correct fuse location.
9. Remove the Red 10 Amp INJ Fuse or and insert the Add-A-Fuse in its place.
