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

See etrailer.com's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your vehicle

Video Transcript for Draw-Tite Brake Controller 20127 Review

Today we're going to review part #20127. This is the draw-type replacement brake controller plug-in wiring harness for the Tekonsha and draw-type brake controllers. Now this is a replacement plug-in harness designed to fit the Tekonsha P3, the Voyager, the Prodigy, the Primus brake controllers. Also works with many of the draw-type brake controllers also. Total length on this wire, just to give you an idea here, just stretch it out, you can see it's right at about 12 inches approximate total length on it. Just to show you what this is used for, I happen to have here a Tekonsha Prodigy P3 brake controller that we do sell separately on our website. Basically what you would do is take the end with the plug into it, you'll see it'll match the back of the brake controller, just push it in, that locks into place.

Then you have your wires to be wired to your vehicle and each wire is marked with a tag that tells you how to connect it or where it connects to. Basically your blue wire would go to your brake output to the trailer. Your white wire would go to the negative side of your battery. The black wire would go to the positive side of your battery. The red wire would go to the cold side of your stoplight switch.

When you need to take your brake controller out, you just push up on that, it pops right out. That should do it for the review on part #20127. This is the draw-type replacement brake control plug-in harness for the Tekonsha and draw-type brake controllers.

Comments

We do not have any instructions for this item either, but I do a help article that explains the details of how to install this item. This is a hard wire application for Draw-Tite or Tekonsha branded brake controllers, this is where the black plug end will install. The loose wires will then be connected to the corresponding functions on the vehicle: Blue: trailer brakes White: vehicle battery negative terminal Black: vehicle battery positive terminal Red: cold side of stoplight switch

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

Brake controller (5100) seems to be operating as wanted, no complaints, glad I got it. Installation was pretty simple, first time always takes longer because some of us like to double check the connections, and there is always a little hesitation about placement. But any real problems are solved by a simple contact with someone at etrailer anxious to help and put your mind at ease. I have not had any problems with the several etrailer purchases I have made. My Vehicle is a 2014 KIA Sedona and I pull a Casita with it. I bought the receiver hitch, brake controller, air suspension enhancement, and maybe 1 or 2 other things. All good. Great people to deal with. 695060

2008 Chevrolet Tahoe

This electric brake controller was just what I needed for my 2008 Tahoe. The videos and info on the etrailer website were a great help in locating the wires I needed to hook up. In addition to the DrawTite 5100 I bought a 20127 cable so that I can easily removed the brake controller should I ever want to. I mounted my brake controller on the left side just above the parking brake pedal. There is a single screw on the underside of the dash there that I was able to use without having to drill any holes. Being able to reach down with my left hand to squeeze the braking button seemed more ergonomic to me than doing it with my right hand and a right hand location didn't have as good a visibility. 678208

  • Recommended Trailer Brake Controller for 2012 Chevy Silverado
  • For your 2012 Chevy Silverado, I highly recommend the Tekonsha Prodigy P2 Trailer Brake Controller # 90885. This is an excellent proportional controller that will activate the brakes on your boat trailer at the same time and with the same intensity that you apply to them in your truck. It features an easy-to-read digital display, 3 boost settings, and continuous diagnostics that will alert you to any potential issues. This unit is well known for its reliability and ease of use.

  • 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. The Prodigy P2 is more of an entry level brake controller; easy to use, easy to mount, and it works well. That is probably why it is

  • 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

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.

  • Can Trailer Brakes be Added to Motorcycle Trailer Axle
  • When adding brakes to a trailer the first thing you will need is a brake mounting flange on the axle. If you do not have a brake flange I recommend part # 4-35. This should be welded in place by a professional welder because it needs to be square and concentric. Beyond that step we have to first determine what hubs/spindles you have on your trailer so that we can first fit a hub/drum (if available) to it and then install assemblies as well.

For the Dexter brake controller, # 58-8 you referenced, you would need wiring harness # 3020-P. To wire in your 7-Way that you have you will need to hardwire

  • 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.

  • Brake Controller for Towing a Trailmaster Trailer with a Harley Electra Glide Classic Motorcycle
  • I have spoken with small tent trailer manufacturers about which brake controllers are best for their trailers with brakes and found that they recommend using a a time delayed brake controller for their trailers. They said that many of their customers have excellent performance from the Activator electric trailer brake controller by Draw-Tite, # 5100. The advantage of a time delayed brake controller on a motorcycle is that it can be positioned in any way, so you can easily find a mounting

  • Wiring a Brake Controller on 2010 Chevy Silverado
  • You are correct, the tow package wiring in your Silverado does not match up color for color with the controller. The red/black tow package wire will connect to the black wire on the controller. The dark blue tow package wire connects to the blue wire on the controller, the light blue tow package wire connects to the red controller wire, and the white tow package wire connects to the white wire on the controller. The orange tow package wire is for an illumination circuit and is NOT needed.

  • 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

  • Does the Tow Package Wiring on a 2008 Chevy Colorado Match a Brake Controller Color for Color
  • On the 2008 Chevy Colorado with a factory tow package, the wiring for a brake controller is located under the dash, to the left of the brake pedal. The wire bundle should have a white tag on it that also lists the functions of each wire. You will need to match the wires to the brake controller by function, not by color. On the brake controller, white is ground, black is 12 volt power, blue goes out to the trailer connector, and red is in from the stop light circuit on the brake switch. It

  • Installing a Trailer Brake Controller on a 2012 Dodge Caravan with Tow Package
  • I spoke with a colleague who worked at Chrysler and he stated that they do not put the trailer hitch and 7-Way wiring on the Grand Caravan at the factory. That is something that the dealer installs. In any event here is what you will need to do. The brake controller will need to be hardwired into the vehicle. The white wire on the brake controller will need to get connected directly to the negative terminal on the vehicle battery. The black wire will need to connect to a 30 amp circuit

Since you have a 2008 this newer body style has been known to need to be hardwired when installing the brake controller to function properly. I have linked a step by step Help Article for you to look at. I would also recommend to clean out any corrosion

  • Electric Trailer Brake Controller Recommendation for a 2009 Volkswagen Touareg TDI
  • I recommend the Tekonsha P2, # 90885. It is one of our highest rated and most popular brake controller models. If your Touareg has a factory tow package, then you will just need to connect the wires from the brake controller to the tow package wires under the dash. The tow package wiring may be located behind the lower appearance panel beneath the dash and to the right of the emergency brake pedal. It may be on the left, wrapped in grey foam.

  • Installing a Brake Controller on a 1988 GMC K 1500 Pickup Truck
  • GM did not install a brake controller adapter port in the C/K series pick up trucks, so there are no plug-in adapters that will allow you to install a brake controller without having to run wires. If you already have 7-way connector at the rear of your truck, then you could use wiring kit # 5506. This kit includes a duplex wire to run a brake output circuit from the brake controller to your 7-way and to run a wire from the brake controller to the battery (via the circuit breaker) and

  • Recommended Wiring Harness for 2018 Buick Enclave and Tekonsha Brake Controller
  • For your Tekonsha Brake Controller, the custom wiring harness # 3026-P is not a confirmed fit for your 2018 model as it was for your 2011 model.

  • How to Find the Brake Switch Wire to Install a Brake Controller in a 2013 Ford Edge
  • Traditionally (at least from 2004 to 2007) Ford has used a green wire on the brake switch to attach to the red wire on a brake controller. However, the only way to know for sure is to test the wires using a circuit tester like # 40376. Manufacturers can use any wire they want and if they run out of the normal color they use, they grab whatever is available to keep the assembly line moving. To test the wire use the circuit tester to probe the wires. You need the one that only shows power
