Specs:
You can adjust the gain setting (also known as braking output) on the Hayes Energize III+ using the thumbwheel on the front of the module. This will set the maximum amount of power that will be applied to your trailer's brakes. You want to go as high as you can without the trailer brakes locking up. Typically, the gain is only readjusted when you experience changing road conditions or if you switch over from a heavy, loaded trailer to a much lighter, empty trailer, or vice versa. To get more power to your brakes, turn the wheel up. To get less power to your brakes, turn the wheel down.
The red LED indicator on the front of the module will light up when the brake controller is activated. This way you can keep your eye on your braking and be sure that it's working.
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.
The Hayes Energize III+ comes with a built-in, easy-to-reach slide-bar manual override, 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, toward the center of the controller. 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.
The Hayes Energize III+ is easy to mount wherever you want it. Simply use the bolts or the double-sided tape to secure the included mounting bracket to your dash, and then install the controller in the bracket.
If your vehicle already has a plug-in brake controller wiring harness, just connect the unit to it. Otherwise, you will need to purchase a vehicle-specific wiring harness (sold separately) to plug into. If a harness is unavailable for your vehicle, hardwiring will be necessary.
Because the Hayes Energize III+ operates with an internal inertia sensor, it must be mounted between -35 degrees and 90 degrees vertically. The brake controller also needs to be horizontally level and parallel with the direction of travel to function properly.

Note: One of the following will be required to ensure proper installation:
The Hayes Energize III+ 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 Energize III+ uses a pendulum system to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It detects 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.
Is this right for you? Product Expert Kathleen M says:
Install your Hayes electric trailer brake controller quickly and easily with this custom wiring adapter. One end plugs into the controller, and the other plugs into the built-in port beneath your vehicle's dash.
Features:
To install your Hayes 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, in which the wiring is run for you from the dash to the trailer connector on the back of your vehicle. Usually when this is done, a port is installed at your dash so that you can easily plug in a brake controller.
For most applications, the factory plug is located beneath the dash, near the center console.
No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

E-trailer has always been my go-to for all my truck and camper needs!
This is my second order with etrailer. Both experiences with your company have been very positive. The knowledge and friendliness -along with following up on orders and satisfaction have been much appreciated. Brittany, the customer representative, is a huge asset to etrailer.
Controller installed easily. Unit applies brakes ok. My big concern is the
lack of the voltage setting being displayed. This is first controller I have
worked with. Video says good back unit. Ok that it is. But if I had known what I know now, would have purchased unit with digital voltage setting. Setting wheel to same spot each use is causing me to go through setting process each time. There is a difference with brakes with unloaded and loaded trailer.
The controller is not at all smooth in applying brakes. very abrupt in braking, have tried adjustments and mounting with no improvement. Would not recommend.
Works like it should. Easy install. Other models will offer more features, but for a part time camper puller like myself, it does the job
It continues to do its job flawlessly. Have not had a single concern with it while towing. It allows for manual application of braking "pressure", but except for testing it at low speeds to verify operation, I have not had to touch it at all while highway towing, as it achieves smooth, even stopping power. Still very pleased with the purchase!
Easy to install and great customer service. One problem: writing on instructions was so small I had to use magnifying glass to read it and my vision is 20/20. This needs to be corrected by manufacturer. Instead of tiny writing in several non English languages, print it so the vast majority of customers can actually read it. This would probably eliminat e many customers calling etrailer for help in installation.
Works perfectly. 1 year and counting.
The plug and play wire harness that I ordered for my pickup should have been 5-6 inches longer. Otherwise everything was fine.
Remember the adage, "you get what you pay for"? Certainly applies here...I will never know if this unit was faulty when I received, or if it simply is poor quality. But the "gain" function on it does nothing, and therefore I can't dial in the sensitivity that is needed. Again, I don't know when/how it became inoperable, but I just ordered it's replacement. Am hopeful for a better experience...
Appreciate the installation videos
Easy to install. Clear instructions.,Works great.
Great service good people to deal with
Nicole was outstanding in knowledge and patience with me. She helped me get through my mistaken order and get me the right brake controller and adaptor harness for my truck. I installed it in less than and hour and it is working great. She also made the return of the controller and harness a breeze.
work's great, thanks
Perfect, exactly what I needed great price, fast delivery, easy installation. It only took about 30 minutes total. The hardest part was for an old man to get down that low in the floor well. Thanks again etrailer.
This brake controller has worked great no problems at all I would recommend it to anyone using this style of brake controller.
Got tip off Utube for the wiring harness adapter for a 2019 Ram. Installation was plug and play. We have a 26 ft camper we will be towing. Very easy install.
I have a 2017 Ford Explorer Sport with the 5000lb tow package and there was contradictory information about the factory installed grey brake controller connector being there. I ordered the Hayes Brake Controller and the wiring harness and took a chance. I had taken a look before ordering but couldn’t see it. Once the parts came I went ahead took off the plastic panel under the steering wheel and the metal plate underneath it. Tucked high underneath steering wheel the grey plug is there. Plugged in the wiring harness replaced the metal plate, attached the Brake Controller bracket to one of the screws that holds the plastic panel. Done. It took less than 30 minutes. I haven’t hooked up a trailer yet, so I have no comment on the actual usage of the Brake Controller. But if anyone has a question about the grey plug for the factory installed brake control wire on a 2017 Ford Explorer Sport, it’s there.
Once my son-in-law tracked down a burned out fuse and we eliminated the previous owner's wiring mess at the back bumper, the new brake controller and adaptive wiring turned out to be "plug and play" on my '96 F250. Worked just as easily as the wiring harness from etrailer that got me trailer brake lights from my '94 Jeep XJ several months ago. If I need something else for trailers, I'll check etrailer again.
Simple install with wire harness from etrailer, plugin, adjust, done. Works and does what I anticipated.
Best of the four brake controllers I've had so far in my truck. Easy to adjust on the fly if brakes are too strong or weak. Manual override felt solid unlike some controllers out there. The instructions could've been written a little clearer though. 4 prong square plug also fits Curt controllers if swapping. Overall nice controller for the money, should've bought this one first and saved the cash
I needed a brake controller for my vehicle that I am going to use for towing a new travel trailer I purchased. I found the etrailer site on the internet and was able to quickly locate an appropriate controller and vehicle specific connection cable. My order arrived in a timely manner. All of the necessary installation information was included and I was able to install it in my vehicle in just 20 minutes. Very pleased with the whole process.
Very pleased with the Hayes controller and the installation videos and information available at etrailer. My installation was hardwired due to an earlier install which removed a connector, so etrailer support was very beneficial plus their price was very competitive...a winning combination.
