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.

The drawtite hitch and trailer wiring harness fit great. Instructions were clear and concise. Installation was a breeze. I am ready to tow my little trailer now. As soon as I get the brake controller installed, I will be ready for my big trailer.



by: Chris C10/09/2016

If your truck comes with the tow haul package.... this item is literally plug and play. I had it wired up and all mounted inside of thirty minutes. It's literally 4 wires and the stock system wires are labeled along with the brake contoller. I haven't tested it yet but so far I am thoroughly impressed!



by: Easy install01/21/2021

Perfectly wired directly to existing wiring that I had for the previous brake controller I replaced with the, Draw Tite I Command. This will make it a lot easier should I choose to upgrade the unit in the future.
Fantastic customer service from Joshua as well.

I installed the Curt gooseneck on my 1993 GMC 2 Wheel Dr. 2500 truck. All the components have tight tolerances. It took me eight hours. With a socket and the wrench. Laying on my back. I did have to cut the wheel well lip about 3/8 of an inch off because I could not get that front angle bar to slide in without hitting it, no way around it unless you lift the bed up and I wasn’t going to do that!!. You have to cut it.instructions do not state that. I’m very happy with the Hitch, it is definitely stout! I did have to make a notch on the outside brackets to go over my airbag bolt. I also had to remove the support bracket on the inside of the frame for the airbag and the crossmember for the spare tire to get the front angled bar in.



by: Douglas08/03/2023

As always, etrailer delivers. Part was on time and a perfect match for the brake controller. What you don't get from Amazon is the technical support on how to install or use the equipment purchased from etrailer. That's why I keep coming back!



by: Don 03/07/2021

My truck was stolen and wrecked. I was able to retrieve the Tekonsha Brake controller from under the Dash board before it was hauled to the salvage yard, but not the wire harness. I was ale to order a replacement harness from eTrailer and reinstall the controller in my new truck. I had no problems at all. Thank you eTrailer for the great support.

These guys are great they had the installation kit it came with everything you need and even had a video for my specific vehicle to install the brake controller and wire in a 7 pin trailer plug
If you don’t have factory brake controller the etbc7 is an amazing kit they have comes with everything I mean everything

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: Chad07/13/2021

Works as intended, but the plug on the back of the controller is a loose connection. Sometimes I would go to brake and find that I had no trailer brakes because the controller lost power. After a wiggle it would start to work again. I was able to shave the Molex plug a bit and now I don't have any problems with it.

Wiring harness I used to connect into the trailer brake control circuit. Requires pulling some inside trim in the drivers footwell area to access my 2022 Chevy Colorado's wires. Follow the intructions or better yet go onto YouTube for video on what goes where.



by: Shad11/01/2022

Works great. FYI YOU HAVE TO RUN A BRAKE WIRE FROM THE CONTROLLER TO YOUR LIGHT PLUG . For it to work properly.



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!

2008 Honda Pilot

Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat, Item # ETBC7
I installed this 7-pin plug kit on my 2008 Jeep JKU to add power and trailer brake control.
I also purchased :
Draw-Tite I-Command Trailer Brake Controller Item # 5535
and
Curt No-Drill Bracket Item # C57202
along with a little extra wire, just in case.

The kit quality was great. It shipped with everything I needed, sans the controller and bracket above. I used a cordless drill, a quarter inch drive socket set, screwdrivers, wire cutter/crimper, pliers, black electrical tape, half inch loom (plastic flexible conduit) and quite a few extra zip-ties I had laying around. I needed the Curt bracket to mount the 7-pin plug farther away from the muffler that runs parallel to the bumper in Wranglers.

I first ran the grey jacketed wire from the rear bumper all the way to the engine compartment. This was the hard part for me since I'm old and a little more round than I'd like. I didn't need to raise the jeep since it already has a 2 1/2 inch lift. I zip-tied the jacketed wire to the frame and brake lines until I found a spot in the frame I could run it through. I ran it out of the frame at the rear of the left front wheel well and up into the engine compartment. There is a (very handy) rubber plug in the firewall just to the left (outboard) side of the brake vacuum booster. I made a small slit in the rubber plug. I removed the outer jacket from the wire at that spot and fed the white (future brake controller wire) into the cabin of the jeep. I ran the black wire, in a wire loom/conduit across the top of the firewall to the battery. I had enough extra wire to run the brake controller power and ground wire from the battery, across the top of the firewall in the same conduit, and into the cabin through the same rubber plug/grommet. I drilled small pilot holes to mount the two circuit breakers. I then connected the wires at the 7-pin plug at the rear bumper. I again made a pilot hole and then mounted the ground wire with the self-tapping screw provided in the kit.

Here I'd like to mention, I would have been happier with heat-shrink connectors. I could have gone to town and bought some, or I could have soldered the connections. Instead, I just used the provided connectors and a LOT of black tape. If I have any corrosion issues later I will replace the connectors provided in the kit.

I wired and mounted the brake controller. This would have been super easy if I could fit under the dash. I dislike using the little blue inline wire connectors (self stripping connectors) but it was a godsend when working one-handed under the dash. I mounted the controller bracket and covered most of the exposed wiring with black tape for aesthetics.

If I was 20 or 30 years younger, I would have had this whole kit installed in about 1 1/2 hours. I am very happy with the quality of the materials. Many others have already noted the bracket is not quite perfect where it is designed for the four wire plug to slip in. The four wire plug had moved slightly on my 20 minute drive to work and would likely have fallen out if I went much further. I may put a wrap of electrical tape around the plug to tighten up the fit. Otherwise I will see if a zip-tie or a drop of superglue will hold the four wire plug in place. I was a wee bit skeptical about the sturdiness of the no-drill bracket as it's held in place by what looks like a hose clamp. I am happy to report, the clamp is heavy duty and well made. The no-drill bracket with the 7-pin and 4-pin receptacles are very sturdy and secure. The instructional videos on etrailer's website made the job easy to understand.

If I had this job to do over again, I would definitely use the same products from etrailer.



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: Beck05/28/2022

One year later I'm extremely pleased with this purchase. I often chuckle when I see stock hitches and the whole thing is visible while mine is neatly tucked under with everything hidden except for the 2" receiver. 10/10 have recommended etrailer on many occasions to friends and family for their service and know-how. Since installing my hitch I towed a pop up camper 1500+kms and do frequent trips to the dump or my local dirt and gravel yard for supplies. Love it!



by: Ken D.02/22/2022

Both the 2017 & 2018 Winnebago Forza class A motorhomes DO have in place (under dash) connections for trailer brake controllers, unlike as depicted on your website as needing an additional part (wiring and 4 prong plug), although it is somewhat difficult to find. Attached to the connection socket is an unwired plug (with blue "lips" in somewhat blurry photo). One could either cut and splice the 12" plug-in harness (#20127) into the vehicle connections, or as I did, use solderless socket connections. To determine what wires go where, use an ohmmeter. You will find two b+ wires (use either one) a ground connection, a brake signal wire(use DC voltmeter and press on brake pedal (engine on in diesel pusher) to get reading, and a to trailer wire (bottom left corner when two b+ and ground wire are on right side of socket).

  • Installing Dexter Predator Brake Controller on 2006 Ford F-150 with Factory 4-Way
  • The reverse light wire on your 2006 Ford F-150 is likely purple or orange, though we have no way to know for sure (manufacturers have been known to change colors so a definitive answer is an impossibility). That said, you can find out pretty easily with Circuit Tester # PTW2979. When installing a brake controller you will need to use this to determine the functions of all wires on your 2006 Ford F-150 which has what I assume is the factory 4-way.

  • 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

  • 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

Once you have found the wire that only

  • 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

  • Tekonsha Prodigy Blowing the IG Meter Fuse on a 2007 Honda Ridgeline RT

  • Troubleshooting Hopkins Reliance Brake Controller on 2008 GMC Sierra 1500

  • 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 # PTW2993. 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
