Proportional Braking

What is proportional Braking

The Dexter Predator DX2 brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.


The Predator DX2 uses an internal 3-axis accelerometer to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.


Large Digital LED Display

The Dexter Predator DX2 features a large LED display that's easy to see so you can check on your current braking output setting with a glance. This display is designed to keep it simple and not overload you with information. The display will also show you the voltage to confirm that the trailer brakes are receiving power.


Braking Output

Dexter Predator DX2 Power Gain Wheel

During the initial setup process, use the thumbwheel on the front of the brake controller to adjust the braking output. The output control lets you set the maximum amount of power that will be applied to your trailer's brakes. Typically, the output is only readjusted when you experience changing road conditions or if the weight of your trailer changes. The power output control on this brake controller lets you set the maximum amount of power that will be applied to your trailer's brakes. Typically, the power output is only readjusted if you switch from a heavy, loaded trailer to a much lighter, empty trailer - or vice versa.


During the initial setup process, you can use the thumbwheel to adjust the power output. To get more power to your brakes, increase the power level. To decrease the power output, lower the power level.


Sensitivity Adjustment with Deceleration Sensor Lever

Dexter Predator DX2 Deceleration Sensor Level

Once you have the overall power set, you can fine-tune the power output by adjusting the sensitivity of the internal sensor. This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does. Boost gets the braking power to your trailer brakes faster and with more intensity so that it doesn't push your tow vehicle forward. To increase the sensitivity for towing heavier loads, move the lever away from you. For a lighter load, move the lever toward you.


Slide-Bar Manual Override

Dexter Predator DX2 Manual Override

The Dexter Predator DX2 comes with a built-in manual override slide-bar in easy reach, great for stopping sway or controlling your trailer's momentum in emergencies. To engage the manual override, just push the slide-bar to the left. This will activate the trailer's brakes and brake lights without you having to apply the brakes on your tow vehicle, perfect for limiting trailer movement while you're cruising.


You can also engage the manual override to help you move a sliding 5th-wheel hitch closer to your truck's tailgate for tight maneuvering during slow speed turns. Just apply the manual override to hold the trailer in place while slowly moving the tow vehicle forward.


Quick, Simple Installation

Because the controller operates with an internal inertia sensor, it must be mounted between -35 degrees and 90 degrees vertically. The Predator DX2 also needs to be horizontally level and parallel with the direction of travel to function properly. During initial installation, the deceleration sensor lever must be positioned straight up and down. After mounting the Predator DX2 using the included bracket, hardwire the controller directly into your vehicle.

Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Pigtail - GM
part number: 3015-S

Streamline the installation of your trailer brake controller with this custom adapter. Simply connect the wires of the harness to your brake controller and then plug the other end into the junction box beneath your vehicle's dash.

Features:

  • Pigtail wiring adapter eases installation of your electric trailer brake controller
  • Connector end plugs into the built-in port beneath the dash of your vehicle
  • Wire end connects to the wires on your brake controller with the included butt connectors
    • Compatible with time-delayed and proportional brake controllers from TrailerMate, Draw-Tite, and Tekonsha
  • Limited 1-year warranty


Installation of Tekonsha Brake Controller Adapter

To install your electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.


Installation 1Installation 2

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


To hook this adapter up to your trailer brake controller, just connect the 4 wires of the harness - ground, power, brake switch, and brake power - to the corresponding wires on the brake controller. If your brake controller came with a plug built into its wiring harness, you will have to cut off the plug and connect to the wires themselves.

This unit works very well. Was able to position it on the dash for convenience with out looking like an add on.

Finally a brake controller that does what I set it to, not what it’s little computer brain, designed by someone who has never pulled a trailer thinks it needs to do.

etrailer and especially Alex's customer support have been stellar. I needed precise information and help with setting up a new tow vehicle. Alex provided details about brake controllers that started from the ground up and got me into a no nonsense controller that is plug and play. I have not had time to install it yet but it's on my to do list this week as well as installing the new mirrors I also purchased a few weeks back. etrailer gets 5 stars plus!



by: Michael 09/22/2022

I installed this controller in my 1982 Chevy K20 pickup.
It works perfectly! Etrailer exceeded my expectations with their level of customer service from the time the order was placed to the products arrival at my home. Truly 5-star service!
The video tutorials are straight forward and very helpful.
The universal installation kit literally had everything needed to complete the job.
Side note:
I would have liked to see the (2) 10ga wires in the insulation to be black and blue, not black and white, no biggie, black on black and white on blue.
Thanks again!



by: Bob J.09/07/2016

I am very satisfied with the Dexter Axle Predator Electric Brake controller. I purchased the Dexter brake controller to be compatible with Dexter car trailer axles on a 16 foot car hauler. The braking unit is very useful when towing in very steep and winding mountain terrain. I feel that the braking is a necessary safety item when towing in a hilly or mountainous environment and the Dexter Predator brake controller provides the great control and driver peace of mind knowing that a heavy load can be managed. The unit installs very easily with the proper adapter.

by: Fred09/09/2017

My brake controller was a great match for my needs. I have a 4 brake trailer which gets the proper control from my Dexter unit. From empty weight to heavy load the adjustment is just a slight roll of the knob. I like the digital read out so I can glance down to check system operations. It does great f or me and fit right in to the factory wire set up in my truck

The parts I ordered were shipped and now are installed on a enclosed trailer that carries a variety of motorcycles. The roads are mountainous and treacherous here so I have to be able to 100% depend on my trailer brakes. The brakes have been flawless, giving me total confidence. Perfect parts, great price. Customer service was a 10. Thanks for all your help !

Item was shipped promptly and was easy to install works great on my 20,000 pound felling goosneck trailer with 4 electric over hydraulic disc brakes.



by: Judy01/06/2022

This was very easy to install and wire up. What was not easy was figuring out why I can manually apply my trailer brakes but they do not work when I use the brake pedal. Apparently this is common with early 2000’s GM trucks. The technical people at etrailer were unable to help and I was stuck doing it on my own. Disappointed.



by: Gary M.06/01/2015

Just finish installing the brake controller so I have not seen it in operation. Everything that was needed for installation was contained in the package. Due to limited access due to the chosen mounting location getting two of the side screws started took some effort.

Chevrolet Tahoe

This was a great replacement for the factory wiring. The OEM wiring that came with the Tahoe was about three times longer than it needed to be. This replacement was the perfect length. The connector fit perfectly. The wire gauge was heavier duty than the OEM. The only things I didn't use in the kit were the crimp connectors. I chose to solder.

  • Brake Controller Does Not Have Full Power When Used
  • First, I would go to the 7-way connector and test to make sure you have power. You will want to use a circuit tester, part # PTW2993 to test the wires. Start by testing the Black wire for power, then test the blue wire for brake controller output. To test the blue wire you will need to have a friend help you. With the vehicle in power accessory mode, in park, and parking brake engaged, have them activate the brakes. Next I would check to make sure the Red Stoplight wire is connected

  • Troubleshooting Electric Brakes with Dexter DX2 Controller
  • The manual override lever does not move when you hit your brake pedal but the digital display will light up and give you a reading. The slide is only for the manual emergency braking or to apply additional braking pressure to your trailer as desired and should not move when you hit your brake pedal at all. The description you gave is that your manual override is sticking and not releasing the braking pressure some of the time which would definitely lead to burning up your brake shoes

  • Trailer Brake Controller for a 2008 Saab 9-7X with Factory 7-Way Trailer Connector
  • The 24 pin receptacle you are seeing sounds like the OBD2 port and would not be used for a brake controller. You will need to utilize the owners manual or a Saab technician to locate the wires and to determine the functions of those wires.

  • Brake Controller Recommendation and Installation on a 2003 GMC Sierra with or without Factory 7-Way

So if each wheel on your two axle trailer has a brake assembly, or just two of them, this brake controller will work. Brake controllers are not vehicle or trailer specific, so you will be able to use the best one for your application. I recommend going with a proportional controller because they offer the best and safest braking, and will reduce wear on both the trailer and tow vehicle brakes. I

  • Troubleshooting Predator DX2 Brake Controller that Only Works with Override Lever
  • The controller shouldn't have been showing voltage without a trailer connected. Typically this is caused by corrosion on the 7-way which is putting a slight draw on the circuit and causing the controller to think a trailer is connected. If the controller isn't applying the brakes with the brake pedal typically that's due to an issue with the red wire of the controller though. This wire needs to see 12 volts to know you are applying the brakes so that it can then start activating the

  • Parts Needed To Install Tekonsha Voyager Brake Controller On a 2005 Chevrolet Suburban 2500

  • Brake Controller Does Not Work After Installation on a 2005 Chevy Silverado
  • On certain year Chevy trucks there are additional connections that need to be made under the hood to make everything fully functional. I have included a link to an FAQ article to help you. Make sure that you are plugging in the harness into the spot on the top row, second from the left. The Curt harness you should be using is # C51352.

This is not typically used anymore since brake controllers have digital displays now so it's not needed.

  • Amperage Capacity for Power Wire on a Factory 7 Way on a 2009 Chevy Suburban
  • Typically, the power wire on a factory 7 way is on a 40amp circuit with a fuse or breaker somewhere near the fuse block. Sometimes it can be a 30amp circuit. If you are going to be running more than 30amps, I would call the service department at the dealer you got it from and find out for sure. You could also give the fuse block a quick check to see if it is clearly identified.
