9 best trailer controllers

Trailer controllers are essential components in the automotive industry, particularly for vehicles that tow trailers or other heavy loads. These controllers are responsible for managing the electrical connections between the towing vehicle and the trailer, ensuring the safe and efficient operation of both.

Here are some key points about trailer controllers:

  1. Purpose: Trailer controllers are designed to control various electrical functions between the towing vehicle and the trailer. This includes managing the trailer's lights, brakes, and sometimes other accessories like power winches.

  2. Types: There are several types of trailer controllers, with varying features and capabilities. The two most common types are brake controllers and trailer light controllers.

    • Brake Controllers: These controllers manage the trailer's brakes, ensuring that they work in tandem with the towing vehicle's brakes. This synchronization is crucial for safe and efficient braking, especially when towing heavy loads. Brake controllers come in two main types: time-delay and proportional.

      • Time-Delay Brake Controllers: These controllers apply the trailer's brakes with a preset time delay after the towing vehicle's brakes are applied. The delay is adjustable to suit different trailer loads.

      • Proportional Brake Controllers: Proportional controllers adjust the trailer's braking force in proportion to the deceleration of the towing vehicle. This provides smoother and more precise braking control.

    • Trailer Light Controllers: These controllers manage the trailer's lights, including brake lights, turn signals, and running lights. They ensure that other drivers can see the trailer's movements and intentions.

  3. Installation: Trailer controllers are typically installed in the towing vehicle's cabin, often near the driver's seat. This location allows the driver to easily access and adjust the controller settings as needed.

  4. Wiring: Proper wiring is crucial for trailer controllers to function correctly. The controller is connected to the towing vehicle's electrical system, and wiring is extended to the trailer. It's essential to ensure secure connections and proper grounding to prevent electrical issues.

  5. Safety: Trailer controllers play a significant role in towing safety. Properly functioning controllers help prevent accidents by ensuring that the trailer's brakes and lights operate as intended.

  6. Maintenance: Regular maintenance of trailer controllers is essential to ensure their reliability.This includes checking for loose connections, inspecting wiring for damage, and testing the controller's functions before each towing trip.

In summary, trailer controllers are integral components in towing setups, helping to control the electrical systems of trailers, including brakes and lights. They come in various types, with brake controllers ensuring safe braking performance and trailer light controllers managing lighting functions. Proper installation, wiring, and maintenance are crucial for their effective operation and towing safety.

User questions & answers

Question: My 2001 tundra did not come with a tow package and there is no underdash plug for a brake controller. do the instructions give me wiring information
Answer: Stan,Yes they give you instructions. The controler comes with a wire harness, a connector is on the end of it that you might want to remove and use the wire ends. You probably could order and adapter plug for the Tundra but running the wires yourself will save money. The Hopkins 47185 Multi-Tow Adapter $20.27 has all the wire connections for the rear already prewired. You will need to run 2 12 guage wires from the connector in the rear, one to the controler (Blue) for the Brakes and one to the battery for 12 Volt power to connector if you think you need it back there (RED). Also a 12 guage wire from the battery to the controler (RED). The controler has 4 wires coming from it. 12V Power (RED), Ground (WHITE), Brake wire (BLUE) and a wire (BLACK) that connects under the dash to the stoplite switch at the brake pedal. The ground wire may be long enough, but the rest need to be extended. Use the proper guage wires. The multi tow adapter has all the wires you need to hook up the Tail and Right and Left turn signals, but they to are in a 4 pin plug that is of no use. Cut it off and extend the wires you need to the tail lights. You will need Hopkins 48615 Mounting Bracket $4.98 also. You might need to get a repair manual from Auto Zone to find the correct wires under the dash by the brake and for the Tail and Turn Signals. Hope this helps.Mike
Question: Will this plug directly into my 2013 Tacoma
Answer: If you purchased your Tacoma with a Tow Package there will be a pigtail with a connector on it on the Driver side behind the cover next to the emergency brake. You may need the dealer to find it. You should have gotten a wired pigtail that would have been in the glove box that has an adapter on it to plug into the wired pigtail, if not you will need to purchase that also. That a pigtail will wire directly to the pigtail on the controller and that one will plug into the one on the truck. Make sure you know where to mount the controller so you can make the wires long enough. If you purchase a Tacoma without the Tow package you should get the dealer or an auto shop to wire it in.
Question: will the reese wiring adapter 78124 work with this model on a 2011 ford f
Answer: If you have the factory Ford pigtail for the brake controller, you don't need anything else , it wires right up.
Question: Do i need wiring harness for my 2011 nissan titan or does it come with everything i need
Answer: If your Titan came with a tow package there should be a connector somewhere under the dash. Have the dealer locate it for you. When you order the controler order the harness for that 2011 truck so it will plug into the one provided on the truck. You will have to splice the harnes to the wires coming from the controler. If the Titan didn't come with a tow package you will have additional wiring to do.

CURT 51140 TriFlex Electric Trailer Brake Controller, Proportional

CURT

Based on 427 reviews Check latest price

Product description

The TriFlex proportion-based brake controller features a compact size, a digital display and the ability to manage up to eight brakes at a time. The feature that sets the TriFlex apart from many others is its triple-axis motion-sensing accelerometer. This integrated circuit component allows the TriFlex to detect every motion of your vehicle and trailer with exact precision and to then apply the perfect amount of braking power for every situation. The TriFlex also automatically adjusts brake output when going up or down a hill and is compatible with anti-lock brakes and cruise control. It comes with a mounting bracket and hardware and can be mounted at various angles on your vehicle's dash. Best of all, like other CURT brake controllers, the TriFlex is protected by a limited lifetime warranty. This CURT trailer brake controller is designed to work with quick plugs so it can readily plug into your vehicle's original equipment socket. It also includes a mounting bracket and hardware for easy installation. A brake controller should be mounted somewhere on the dash of your vehicle, and we recommend putting it below the steering wheel, either on the right or left side of the steering column. This way the control will not block your view when driving, but it will remain accessible and visible when adjustment is needed.

  • INTELLIGENT BRAKING. This trailer brake controller operates with an integrated circuit called a triple-axis accelerometer. This circuit detects motion on three planes and provides braking power accordingly, up or down a hill
  • EASY ADJUSTMENT. The TriFlex brake controller is highly adjustable to accommodate different vehicles, trailers and loads. It provides 9 levels of sensitivity adjustment and features driver-selectable power output and manual activation
  • COMPACT DESIGN. This electric brake controller has a sleek, subtle design to avoid dominating the dash of your vehicle. It measures only 3-1/4 inches x 4 inches x 7/8 inches. The TriFlex perfectly balances a compact design with powerful operation
  • VERSATILE. You can use this electric trailer brake controller on virtually any trailer with 1 to 4 axles (2 to 8 brakes). It is also fully compatible with cruise control, anti-lock brakes, low-voltage systems and PWM systems
  • SIMPLE SETUP. Installing and setting up the TriFlex trailer brake controller is fast and easy. It can be plugged into your vehicle in minutes using a vehicle-specific quick plug harness (sold separately). It also has automatic leveling and calibration

User questions & answers

Question: What adapter cable is required for a 2002 Suburban 3.5l 4x
Answer: it's not so much an issue of fitting as much as making sure you get the right wiring harness for your truck which is normally sold separate from this unit. So just do a search for your trucks harness. You can even go to the manufacturers website and look up the right harness model number then search for it on Amazon. Great unit you'll love it.
Question: I have a 2013 silverado 1500 lt. has factory towing package. do i need an additional harness? how do i found out which one if so
Answer: Manufacture states power draw is so low (3.6 milliamps when not in use) that it would take 3-4 months to drain battery if allowed to sit without starting. Then would be the time they would recommend disconnecting unit from vehicle wiring.
Question: Does it have a digital read out to tell you what degree it's currently adjusted to
Answer: Most electric brakes will not "engage" when driving in reverse. The magnets will still grab, yes, but the camming action that forces the shoes to the drums is reversed and thus should not cause any issues.
Question: is this unit "proportional" or "timed
Answer: It comes with a pigtail that plugs into back of unit and stranded wires on the other end to hook up to the car. If you have a newer vehicle that is prewired for electric brakes, you can purchase a pigtail to plug into the prewired side plug. My vehicle came with that pigtail in the glove box when I bought it.

CURT Electrical Trailer Brake Controllers

CURT offers several different trailer brake controller models to provide you with a solution that fits your unique towing setup and budget. We carry time-based and inertia-based or proportional brake controllers.

All CURT trailer brake controllers are designed for easy installation. Most use our quick plug harnesses, and each comes with its own set of features and benefits.

For a helpful guide in selecting a brake controller, see below.

Two types of brake controllers:

CURT electric brake controllers fall into one of two categories: inertia-based or time-based. These refer to the method of activation used by the brake controller. Both types are safe and effective for stopping a trailer. However, depending on your needs, one may be preferred over the other.

Inertia-based

Inertia-based or proportional trailer brake controllers use an electronic mechanism, called an accelerometer, to detect the momentum of the vehicle-trailer combination while braking. The controller accentuates the trailer brakes in proportion to the momentum, allowing for a smooth, highly efficient stop.

Time-based

Time-based activation is less complex than inertia-based. When stopping, a time-based brake controller accentuates the trailer brakes based on whatever gain setting is input by the driver. Although simple in operation, time-based trailer brake controllers are effective and provide a more budget-friendly option.

Heavy-duty towing

If you are towing a heavy trailer or cargo, an inertia-based brake controller will provide superior control to make smoother stops and to put less strain on your vehicle.

Light-duty towing

If you’re towing a simple boat trailer or popup camper, a time-based trailer brake controller may be sufficient. CURT time-based controllers are easily adjustable for varying loads.

Frequent towing

If you’re planning to tow often, an inertia-based brake controller is recommended. The sophisticated operation will help prolong the life of your vehicle and trailer.

Occasional towing

If you only plan to tow a few times a year, such as for family camping trips during the summer, a time-based brake controller is an effective and budget-conscious option.

User questions & answers

Question: Will this fit 2021 GMC 2500hd
Answer: In this hardwired design, only the one initiating the alarm speaks the programmed room name. The other interconnected units do not announce the room name; they only sound the alarm. It seems a little misleading to me from the First Alert description. I replaced 11 old units that were interconnected in my house with this design, and when one goes off, I have to run around the house listening for the unit speaking its room name to find the one that initiated the alarm.
Question: do i need wires or more things to buy in order to install this break control
Answer: I own 8 of these and that answer is false about only one doing voice annunciation. What a crazy idea that would be if the voice annunciation that is meant to warn you of the area to avoid during an evacuation, and it only announced it in the very room you are to avoid. That person is wrong and you would die if you ran around. He misconfigured his detectors.
