Fits: 2024+ Toyota Tacoma (4th Gen) or 2022+ Toyota Tundra (3rd Gen). Choose your truck when you order.
What it does: A 35 ft cable that plugs inline at the factory third brake light connector and gives you brake light (red), ground (black) and illumination (yellow) wires to run to your topper. No cutting, splicing or crimping into the factory harness.
Streamline your topper installation with our Brake Light Wiring Tap Cable. No more crimping headaches. This 35 ft cable plugs inline on the 3rd brake light connector, saving you time and effort.
Easy Topper Integration: Designed to simplify your topper setup, the tap cable routes the signals your topper needs, with dedicated connections for your brake light (RED), ground (BLACK) and illumination light (YELLOW).
Reliable and Durable: Built from 24 AWG automotive-grade wire with a +85°C TPU jacket, made to handle off-road use and bad weather on your Tacoma or Tundra.
Installation
The Brake Tap connects in-line with the CHMSL (3rd brake light) At the connector in the headliner above the rear seats. Follow Steps 1 and 2 from the camera relocation videos to drop the headliner. Then skip ahead to the wire routing and route your brake wire through the same grommet under the seat to the tailgate.

FAQs
1. Does this work on my specific truck?
This cable is compatible with 2022+ Toyota Tundras and 2024+ Toyota Tacomas.
CRITICAL REQUIREMENT: Your truck must be equipped with a factory CHMSL that includes the white illumination/cargo lights. If your cab light does not have the white clear lenses next to the red brake light, this harness will not be compatible. This includes select 2025/2026 Tundra trims and Tacoma SR trims without the LED cargo light package.
2. Which version should I buy: Tundra or Tacoma?
While the technology is similar, the harness lengths and connectors are vehicle-specific. Please ensure you select your correct truck model from the dropdown menu before adding to your cart to avoid shipping delays or return issues.
3. Is it "Plug-and-Play"? How hard is the install?
Yes! Our harness is 100% plug-and-play with no wire cutting or splicing required. You can find our step-by-step video guide at ggoffroad.com/install to see the process before you buy. Most customers complete the install in under 20 minutes.
4. What are the technical voltage outputs?
The harness provides two distinct 12VDC triggers:
- Red Wire: Outputs 12V when the brake pedal is pressed.
- Yellow Wire: Outputs 12V whenever the white CHMSL/Cargo lights are activated (e.g., when doors are open or the cargo light switch is on).
- Black Wire: Ground.
5. Will my factory 3rd brake light still work?
Yes. Our harness acts as a "bridge." It taps the signal for your topper or accessories while allowing the factory cab brake light to continue functioning exactly as it did from the dealership.
6. Why tap the headliner instead of the tail lights?
Many DIY taps at the tail light cause "hyper-flashing" or turn signal interference because the truck’s computer detects a change in resistance. By tapping the CHMSL in the headliner, our cable avoids the blinker circuit entirely, ensuring zero interference and a clean signal.
7. Can I use this to power LED bed lights?
Absolutely. While designed for topper brake lights, this is a perfect power source for low-draw LED bed lighting. You can use the yellow wire to have your bed lights turn on automatically when you unlock the truck or open the doors.
8. Why does the brake tap wire have two different connectors?
The brake tap connects between the truck and the existing brake light, leaving it fully functional while tapping into signals and providing 26ft of cable to use elsewhere.

Works great! Little different back seat configuration if you have the Tacoma hybrid. Grommet is still located in the same general area but have to wire it around the battery under the seat. Other than that it was a simple install.
Thanks Judd! Really glad it worked out and appreciate you documenting the hybrid-specific routing.
Our Tundra install video is on a hybrid so it can help to review that routing.

Excellent Product

Worked great! Love that I didn’t need to cut any wires.

The pigtail made installing one of the most difficult wiring runs a whole lot easier. Getting the headliner down was the hard part. Instead of pulling it all the way out to run wire taps and splice cables, all you have to do is disconnect the harness and click in the pigtail connectors. And it's more than long enough to run through the cab and out to the bed.
Since this one's about the product and the install, Austin signs it:
Thanks for the write-up.
You're right that the headliner is the worst part of the job. We can't do anything about that. What we could fix was the splicing. Toyota's third brake light harness already has connectors in the headliner, so the cable plugs in between them and nothing gets cut. That also means you can put it back to stock later.
Good to hear the length worked for your cab-to-bed run too.

Saved me a bunch of time and was a lot easier than making my own wiring solution. Well worth the cost for the time saved, parts saved, and convenience. Great customer service too.
Thank you for the kind words, Matthew! Glad the product helped you out
