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: 3016-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.


This adapter plugs into the 4-pin connector in your vehicle's junction box. The box is located underneath the dash, to the left of the steering column, just above the carpeting.


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.

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.



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: roula m07/25/2017

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 !



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

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: 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.

Do you have a question about this Trailer Brake Controller?


  • Where Do the 4 Wires of a Brake Controller Go for Installation in Vehicle
  • The four wires and their functions are: White: Ground wire, connected to negative side of battery. Blue: Electric brake wire, ran to the brake output circuit of your 7-way with 10 gauge wire like # 10-1-1 sold by the foot. Black: 12v power wire, connected to the vehicle positive battery terminal with a 40amp circuit breaker, part # 9510. Red: Stoplight switch circuit. This will get run to the wire on your stoplight pedal assembly that sees voltage only when the brakes are applied.

  • How to Install a Brake Controller in a 1996 Dodge Ram
  • If your 1996 Dodge Ram has the factory 7-way connector at the rear of the vehicle, then all of the wires for the brake controller have been run. You will just need a brake controller wiring adapter. I recommend using part # 3020-P and cutting off the black plug. This adapter plugs into the brake controller plug under the dash, to the left of the steering column taped to another harness near the emergency brake pedal. The four pigtail wires on the other end will be butt-connected to the

  • Will the Dexter Preadator Brake Controller # 58-8 fit a 2006 Cadillac SRX
  • Yes, there is a way to install the Dexter Axle Predator Electric Brake Controller # 58-8 in your 2006 Cadillac SRX. The first thing you need is a 4-way trailer connection at the rear of your vehicle. You may already have this, but if not you will need part # C59496. This comes with everything you would need to install the 4-way, I attached install instructions and an install video for you to check out also.

  • 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

  • Installing Trailer Brake Controller on 2012 Chevy Silverado with Factory 7-Way
  • If your 2012 Chevy Silverado is equipped with the factory 7-Way connector at the rear there isn't an actual OEM port behind the dash for a brake controller plug-and-play install, however all the needed wiring is present. This means you can simply hardwire the Dexter Predator DX2 Brake Controller # 58-8 directly to the factory wire bundle behind the dash of your truck. Based on my research these blunt cut wires are behind the steering column. You will make the following connections using

  • Can the Dexter # 58-8 Predator DX2 Brake Controller Be Installed Vertically
  • According to Dexter, the # 58-8 Predator DX2 needs to be mounted in the direction of travel, level on a side to side plane. If mounted on vertical plane as you mention, the brake controller would not function. If the vehicle design somehow limits the installation options, and you have no other option than to mount a brake controller vertically, you can use a time delayed brake controller like the # 5504 Draw-Tite Activator IV. Because the controller is solid state, if can be mounted

  • Troubleshooting Low Power Output for Predator DX2 Brake Controller
  • It sounds like you've done a good amount of troubleshooting already which gives us a good foundation to work off of. Since your Dexter Predator DX2 Trailer Brake Controller # 58-8 isn't supplying more than 3.2 for power this tells me that 1 of 2 things is going on; either there isn't enough power getting to the controller and is limiting it, or something is internally wrong with the controller. Start off by checking the wires connected to the controller first. The white should have

  • Is the Dexter Predator DX2 Trailer Brake Controller Compatible with a Triple Axle Trailer
  • The Dexter Predator DX2 Trailer Brake Controller # 58-8 is only rated for up to 2 axles. If your trailer has 3 axles then I recommend the Tekonsha Primus IQ # TK90160 which is a proven proportional brake controller at a cost-effective price. This also uses the same wiring configuration as the DX2 so if you are splicing it in to your tow vehicle you will use the following: Blue - 7-Way Output to Trailer Black - 12V Power White - Ground Red - COLD Side of Stop Light Switch (only gets

  • Trailer Brakes Lock Up When Brake Pedal is Pressed Even With Controller Turned All the Way Down
  • Have you tried towing the trailer with another truck? Or towing another trailer with the Dodge? This would help you narrow down whether the problem is with the wiring on the vehicle or the trailer. From what you're describing, it sounds like either something's incorrectly wired on the vehicle or trailer, or the trailer connector on the vehicle is damaged or corroded. This is kind of a strange occurrence, so try what I've mentioned above and get back with me. I've also linked you

  • Should Brake Controller Draw Power All The Time
  • You won't have any problem with power going to the brake controller all the time. This lets the brake controller keep all of its settings and not lose them every time the vehicle is turned off. Brake controllers are designed to enter a sleep mode after a period of time when there is no activity. An idle controller draws very little current and will not drain the vehicle battery.

  • 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

  • Surge Brakes or Electric Brake Controller for a Trailer Towed by a Motorcycle
  • Electric brakes and brake controllers do require adjustment when the trailer changes weight due to adding or removing a load. As long as you remember to do that there is no problem with the brakes being too aggressive. Surge brakes require a certain amount of momentum, inertia to activate the trailer brakes. The reason you do not see them on trailers towed by motorcycles is because those trailers are light and it does take a lot of pressure to activate the brakes that just isn't present
