The Brite Box – Install and Review on 5th Gen 4runner

The Brite Box (Anytime High Beam + Low Beam + Fog Lights) – Turn On all Forward Facing Headlights At The Same Time

“The Brite Box” is a very fitting name for this awesome product that lights up the road in front of you. Installing this on your vehicle will allow for all the lights (low beam, high beam, and fogs) to turn on when you flip on the high beams. This is something that I always wished vehicles came with, but assume there are some DOT regulations against it. The high beams on our 4Runner are used to get the brightest light output possible for better visibility down the road. With The Brite Box, you combine this light output with the Low Beams and Fog lights!

For this install, I chose to add the “Anytime” feature. This allows you to turn your fog lights on without the need to have your lights on. You can choose this option or the “Fogster” option if this isn’t something you want or need. The install is much easier if you choose this Fogster option. Nate, another writer here for Trail4Runner.com covered a Brite Box Review on TrailTacoma.com as well.

Step 1. Remove Bumper Cover Bolts

Using a 10 mm socket and wrench or drill remove the 3 bolts. This kit only requires installation on the driver’s side. You will not need to repeat this step on the passenger side.

Step 2. Release Bumper Cover

On the driver side, gently pry the top clip over the bolt hole and pull the bumper from the lower 2 clips. Using the flat trim tool here helps. Once you have these out, pull the bumper towards you. The cover is snapped in place and takes a little force. You will hear a few popping noises; this is not plastic breaking.

Step 3. Unclip Fog Light Connector

For this step, you will need to reach your hand in between the bumper cover and the wheel well liner. There is a black clip on the fog light connector that you will need to press and then pull down.

Connect Brite Box to the fog light connection

Next, you will connect the module to the fog light connection. If you haven’t already, pop the hood and run the fog light wiring from the Brite Box down behind the driver-side headlight. You will want to keep the Brite Box module (black box) up top for mounting, along with the positive and negative wires (black and red). Once you have the wires down near the fog light, connect the current connection to the Brite Box connector and then the wire labeled “Fog Light” to the actual fog light.

Step 4. Mount Brite Box Module

Using the provided zip tie, mount the box to the wire loom (this seemed to be the best place I could find). The instructions detail how you should ensure the wires are running down, in the event of any water getting inside of the box.

Step 5. Run the Ground Wire

Using a 10 mm socket and wrench or drill, remove the ground bolt and attach the ground wire

NOTE: If you chose the “Fogster” option, at this point you have completed the install and can test functionality.

Step 6. Modify the Positive Wire

The step of running an add-a-circuit is optional but highly recommended. The provided instructions with the “anytime” fog light feature will have a switch that you can toggle the fog lights on and off. The problem with using the provided instructions and not following this step is that you run the risk of leaving your fog lights on and coming back to a dead battery since this is directly wired to the battery.

Using the wire crimping tool, snip the wire to remove the black add-a-fuse that came with the Brite Box.

Place the black heat shrink over the add a circuit wiring

Strip the positive wire and connect it to the add-a-circuit and using the wire stripping tool, crimp the butt splice.

Using a heat gun or lighter, heat the heat shrink which will shrink to ensure a watertight seal.

Step 7. Connect the Add-A-Circuit

Open the engine fuse box. On the back of the box locate the fuse labeled “INJ”. Using the white fuse puller in the fuse box remove the 10 amp fuse. Add this fuse to the add-a-circuit along with the extra 10 amp fuse that came with your add-a-circuit, install it back into the “INJ” open slot. Run wire out the back of the fuse box and add the cover back.

NOTE: At this point, if the vehicle is turned on the wires are live. Avoid starting the vehicle until all wires are connected and ready for testing. You can leave the add-a-circuit disconnected, or fuses removed, and reattach when ready to test.

Step 8. Remove the Wires From the Switch Connection

Insert a small flathead screwdriver into the open end of the switch connector. Press down on the metal connection and pull the wire out from the back. Repeat this step on the other 2 wires.

Step 9. Prepare Wires to Run Through the Firewall

To run the wires through the firewall you will need something to help poke it through. There are probably some better options, but a coat hanger seemed to work well for me. Take the wire coat hanger and cut the bottom end so you only have a straight piece. Tape the wires to it using duct tape.

Step 10. Run Wires Through the Firewall

First, remove the rubber grommet that provides access to the interior cabin. You will need to cut a small hole in this grommet and run the wires through it. After this is completed, run the wires and coat hanger through the hole in the engine bay. Using a little force, you will need to pierce through the firewall with the coat hanger. Push it through enough so you can grab it from the interior.

Step 11. Pull Wires Through the Firewall

From the interior, you will need to locate the coat hanger and wires. These will be near the brake pedal mounting bar. Pull these wires through and remove the tape and coat hanger. Be sure to reattach the rubber grommet in the engine bay.

Step 12. Reassemble Wires to the Connector

Next, connect the wires back to the connector you dissembled to get the wires through the firewall. With the connector clip on the right side, the colors should be Top = Green, Middle = Brown, Bottom = Black. Once all the wires are back in place, attach the connector to the switch 4 wire connector.

Step 13. Open Switch Panel

To wire the switch, you will need to open up the switch panel. Grab the right side of the plastic panel and pull it out and down. This will open the backside and allow for easy removal of the switch blank and allow you to run the wires through.

Remove blank switch

There are 2 push tabs on the top and bottom of the blank switch. Push those down and then out towards you, which will pop the blank switch out.

Step 14. Run the Switch Wiring

Run the wires up from the bottom and through the switch panel opening.

Step 15. Connect the Switch and Test Functionality

Attach the wiring connector to the switch. Turn on the 4runner and depress the switch to test. The switch should light up along with the fog lights.

NOTE: If you disconnected the add-a-circuit or fuses on Step 9, you will need to reconnect them here.

Clean up all the wiring in the cabin and engine bay. Make sure to check that all your wiring in the cabin does not interfere with your emergency brake or brake pedal.
