Dexter Predator DX2 Trailer Brake Controller - 1 to 2 Axles - Proportional
part number: 58-8

Brake controller activates trailer brakes in proportion to deceleration. Large digital LED screen clearly displays settings. Gain wheel provides preset levels of braking. Automatically levels when mounted within a 125-degree range.

Features:

  • Brake controller activates your trailer brakes in proportion to your vehicle's braking action
    • Automatically adjusts trailer's braking based on deceleration of tow vehicle
    • Activates immediately - no pausing like with time-delayed brake controllers
  • Adjustable gain setting lets you determine the power output sent to the trailer's brakes
    • Set to higher output when towing in hilly terrain or with a fully loaded trailer
    • Back off power when towing a lightweight or empty trailer
  • Deceleration sensor lever lets you adjust braking aggressiveness
  • Large digital LED display indicates controller settings and monitors voltage output
  • Slide-bar lever allows for manual application of brakes
  • Built-in safeguards protect your vehicle and trailer
    • Manual override illuminates brake lights on tow vehicle and trailer
    • Current limiter protects vehicle from shorts in the trailer wiring
    • Hazard flasher immunity prevents pulsing of the brakes when flashers are activated
  • Quick and easy mounting with included bracket and hardware
    • Controller must be level or within mounting range
    • Pigtail harness hardwires into your vehicle
  • Made in the USA


Specs:

  • Application: single- and tandem-axle trailers
    • Designed for use with electric brakes only
  • Mounting angle: -35 degrees to 90 degrees in the vertical plane
  • Dimensions: 3" wide x 6-1/2" long x 1-5/8" tall
  • 7-Year limited warranty


Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking, or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently


So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in that same manner


As long as the Dexter Predator DX2 controller is properly mounted, it will sense - via an internal sensor - how your tow vehicle brakes. The sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time


Power Output Control

Dexter Predator DX2 Power Gain Wheel

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. Use the lever to achieve your desired degree of intensity. Move the lever toward you to delay the power output, creating braking sensitivity that is ideal for lightweight setups. If you are towing a heavy load, you may want to have the trailer brake more aggressively to prevent it from pushing your tow vehicle. To get a stronger stopping action, move the lever so that it points away from you.


Large Digital LED Display

The unit also features a large digital LED display, which shows the controller's power settings. It also shows the voltage, allowing you to easily identify that the trailer brakes are receiving power.


Slide-Bar Manual Override

Dexter Predator DX2 Manual Override

This unit comes with a manual override lever on the front that lets you activate the trailer brakes without needing to activate your vehicle's brakes. When you use the manual override, the amount of power sent back to the trailer brakes will be the maximum amount of power, regardless of the preset power level you selected during setup. This ensures that you will always get the most effective braking in an emergency situation. In addition to being a necessary safety feature, this option also helps to control trailer sway by slowing the trailer to put it back solidly behind the tow vehicle.


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 in the vertical plane. During initial installation, the deceleration sensor lever must be positioned straight up and down. The device must also be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.


This brake controller is designed to be hardwired into your vehicle.


Installation Accessories

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.

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.

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. 292121

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 430590

  • 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

  • Dexter Predator Brake Controller 58-8 Installation in 2005 Ford F150
  • If your 2005 Ford F-150 has only 4 wires at the bumper (or only a 4-pole connector) and you need to install a 7-way vehicle-side connector, you could use the Hopkins # 37185. If you already have the 7-way connector on your truck, you will need to make the additional wire connections for the brake controller. (The 4 wires you have carry the brake light, running light and turn light signals for your trailer, plus a ground: white = ground, brown = running/brake lights, green = right turn signal

  • Recommended Brake Controller for a 2017 Dodge Durango with Factory Installed Tow Package
  • For you 2017 Dodge Durango, i recommend the Tekonsha Prodigy P2 Brake Controller, # 90885. The P2 Brake Controller is a proportional brake controller, so it applies brake power to your trailer in proportion to the brake pressure applied to your vehicle. You will get a faster braking response with proportional controllers over the traditional time delay.

  • 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.

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.

  • Brake Controller Recommendation and Installation on a 2003 GMC Sierra with or without Factory 7-Way
  • I did a little research and found that the Dexter Predator, # 58-8, is for 2 to 4 brakes. 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

  • 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

  • Troubleshooting Brake Controller that Won't Work with Brake Pedal
  • If a brake controller is detecting a trailer connected when there isn't one connected that indicates that there is a load somewhere on the brake output circuit that is confusing the controller. Typically this is corrosion on the 7-way and cleaning the pins with fine grit sandpaper will do the trick. If a controller will work with the override but not with the brake pedal that indicates a problem with the red (stoplight circuit) wire of the controller. What you will need to do is check
