Does the 2020 Toyota Tacoma Have a Trailer Brake Controller? A Comprehensive Guide

The 2020 Toyota Tacoma does not come standard with an integrated trailer brake controller. However, the truck is pre-wired for one, making aftermarket installation relatively straightforward. This article provides an in-depth look at the 2020 Tacoma’s towing capabilities and everything you need to know about adding a trailer brake controller.

Understanding Trailer Brake Controllers and the 2020 Tacoma

Towing with a truck like the 2020 Tacoma requires more than just a hitch. When pulling a significant load, particularly a trailer with its own brakes, a trailer brake controller (TBC) becomes essential. This device allows the driver to modulate the trailer’s brakes independently of the truck’s, ensuring safe and controlled stopping.

The 2020 Tacoma’s towing capacity varies depending on the engine, cab configuration, and bed length. Models equipped with the 3.5-liter V6 engine and the Towing Package can typically tow up to 6,800 pounds. Without the Towing Package, the towing capacity is considerably lower. It’s crucial to consult your owner’s manual and the sticker on the driver’s side doorjamb for your specific truck’s capabilities.

The Absence of a Factory-Installed TBC and Why it Matters

While some trucks include an integrated TBC from the factory, the 2020 Tacoma does not. This means that if you plan to tow a trailer with electric brakes, you’ll need to purchase and install an aftermarket trailer brake controller.

The lack of a factory-installed TBC isn’t necessarily a drawback. It allows owners to choose a controller that best suits their specific needs and towing preferences. Aftermarket options range from basic time-delayed controllers to more advanced proportional controllers.

Why Proportional Controllers are Often Preferred

Proportional trailer brake controllers are generally considered superior to time-delayed controllers. They apply the trailer brakes in proportion to the truck’s braking force, providing smoother and more controlled stops. This reduces the risk of trailer sway and improves overall towing stability.

Time-delayed controllers, on the other hand, apply the trailer brakes after a set delay and at a pre-determined level of force. While more affordable, they can feel less intuitive and may not be as effective in emergency braking situations.

Installation Considerations for an Aftermarket Trailer Brake Controller

Installing an aftermarket TBC in your 2020 Tacoma is a relatively straightforward process, especially since the truck is pre-wired. The wiring harness is usually located beneath the dashboard, typically near the driver’s left knee.

Finding the Correct Wiring Harness

The wiring harness should be clearly labeled and easily accessible. You’ll need a compatible wiring harness adapter to connect the TBC to the truck’s electrical system. These adapters are readily available from auto parts stores and online retailers.

Steps for Installation

  1. Locate the Wiring Harness: Identify the pre-wired harness under the dashboard.
  2. Connect the Wiring Harness Adapter: Plug the adapter into the truck’s wiring harness.
  3. Mount the Trailer Brake Controller: Choose a suitable location for the TBC, ensuring it’s within easy reach of the driver.
  4. Connect the Controller to the Adapter: Connect the TBC’s wiring to the adapter.
  5. Test the Controller: Use a test light or a trailer with electric brakes to verify that the controller is functioning correctly.

Note: If you’re not comfortable performing the installation yourself, it’s always best to consult a professional mechanic.

Frequently Asked Questions (FAQs) about Trailer Brake Controllers and the 2020 Tacoma

Here are 12 frequently asked questions to further clarify the topic of trailer brake controllers and the 2020 Toyota Tacoma:

1. What exactly is a trailer brake controller and why is it needed?

A trailer brake controller is a device that allows the driver to activate and modulate the electric brakes on a trailer independently of the truck’s brakes. It’s essential for safe towing of trailers equipped with electric brakes, as it provides increased stopping power and control.

2. Is the 2020 Tacoma pre-wired for a trailer brake controller?

Yes, the 2020 Tacoma is pre-wired for a trailer brake controller, simplifying the installation process of an aftermarket unit.

3. What type of trailer brake controller is best for the 2020 Tacoma?

Both proportional and time-delayed trailer brake controllers are compatible. Proportional controllers are generally preferred for their smoother and more responsive braking performance.

4. Where is the wiring harness for the trailer brake controller located in the 2020 Tacoma?

The wiring harness is typically located under the dashboard, near the driver’s left knee.

5. Do I need a special wiring harness adapter to install an aftermarket trailer brake controller?

Yes, you’ll need a compatible wiring harness adapter to connect the TBC to the truck’s pre-wired harness. These adapters are readily available online and at auto parts stores.

6. Can I install a trailer brake controller myself, or should I have it professionally installed?

While installation is relatively straightforward, it’s recommended to have it professionally installed if you’re not comfortable working with electrical systems.

7. What are the symptoms of a malfunctioning trailer brake controller?

Symptoms of a malfunctioning TBC include weak or non-existent trailer brakes, erratic braking, and error messages on the controller display.

8. How do I adjust the gain on my trailer brake controller?

The gain setting determines the amount of braking force applied to the trailer. Adjust the gain gradually, starting with a low setting and increasing it until the trailer brakes engage smoothly without locking up.

9. What is the difference between electric brakes and surge brakes?

Electric brakes are activated by an electrical signal from the trailer brake controller. Surge brakes are activated by the inertia of the trailer pushing against the tow vehicle. The 2020 Tacoma’s pre-wiring supports electric brakes.

10. Does the 2020 Tacoma come with a Towing Package, and what does it include?

Yes, the 2020 Tacoma can be equipped with a Towing Package, which includes features like a Class IV hitch receiver, trailer sway control, engine oil cooler, transmission fluid cooler (automatic transmission models), and a heavy-duty alternator.

11. Will installing a trailer brake controller void my 2020 Tacoma’s warranty?

Installing an aftermarket TBC should not void your warranty, as long as it’s installed correctly and doesn’t cause any damage to the truck’s electrical system. However, it’s always best to consult with your Toyota dealer to confirm.

12. What is the maximum towing capacity of the 2020 Toyota Tacoma?

The maximum towing capacity of the 2020 Tacoma is up to 6,800 pounds when properly equipped with the 3.5-liter V6 engine and the Towing Package. Always consult your owner’s manual for specific towing limits for your truck.

Conclusion

While the 2020 Toyota Tacoma doesn’t come with a factory-installed trailer brake controller, its pre-wiring and robust towing capabilities make it an excellent choice for those who need to haul a trailer. By understanding the importance of a TBC, choosing the right aftermarket option, and ensuring proper installation, you can confidently and safely tow with your 2020 Tacoma. Remember to consult your owner’s manual and adhere to all safety guidelines when towing.
