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:
Designed for applications that do not come equipped with a brake control wiring harness port from the factory, this adapter plugs into your Hayes electric trailer brake controller at one end and the other end splices into your vehicle's wiring.
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. However, if no port is present, you will have to splice into your wiring.
With this universal adapter, you can install your Hayes brake controller without having to wire the controller directly to your vehicle. If your vehicle has a factory tow package, just splice the pigtail end of the adapter into your vehicle's factory brake control harness wiring, and then plug the other end of the adapter into the controller. If your vehicle doesn't have a factory tow package, you'll have to hardwire the pigtail end of the adapter into your vehicle's wiring. Because only the adapter is hardwired to your vehicle, you can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.
If your vehicle is not equipped with a factory tow package, you will need to purchase additional equipment to ensure that the signals from your brake controller are sent to your trailer's brakes. We recommend etrailer.com's exclusive 7- and 4-way brake control installation kit (ETBC7 - sold separately).

Installation was 30 min. Works perfectly. E-trailer has always been my go-to for all my truck and camper needs!
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.
25 minutes after placing my online order with etrailer I got a phone call from a representative, ensuring that all of my order was correct was in stock and was being packaged for shipment. I had all of the parts that I ordered three days later, and a verification email that it was delivered. etrailer Runs their business. The way every business should be run. They take care of their customers from beginning to end and today, one year after the purchase. I got an email from them to find out how things were going. Six stars.
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
High quality wire harness. I had to order parts from VW to make a pigtail to connect to the factory harness. All this and the part numbers were supplied with the instructions through etrailer.
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.
Wiring is NOT conventional..
None of the harness wires matched up to the flat 4 wiring.
Red was yellow green was brown etc.
And wiring or color ceding was included with the 7 pin harness
Exactly what I ordered, helped keep the wiring under the dash organized, delivery of product prompt, all good!!
The plug and play wire harness that I ordered for my pickup should have been 5-6 inches longer. Otherwise everything was fine.
It's a plug and 4 wires. I haven't installed it yet but most likely it will work. It would have been nice if they had the vehicle-specific cable for their brake controller but then maybe my vehicle doesn't have a receptacle (2006 Jeep Commander). Not sure yet, haven't got that far, don't know when I will. I wanted to do it yesterday but it's been cold and rainy here and I don't have room in my garage to work so I've been working on the Jeep in the driveway. I got the trailer hitch mounted the other day and now I'm working on the wiring for the trailer plug. I put the Jeep up on 4 ramps to give me room to get under it and run wiring. At 275 pounds I need the extra space. When the rain stops and the wind dies down I will make an attempt to install this device, but I got this email first asking me for a review and an opinion. I don't really have an opinion yet and I can only write a review of what I know so far, which is very little. The instructions that came with it are quite simple. They tell you to plug it in and then read the instructions that came with the controller that you plugged it into. I was hoping for something more specific, like where should I look for the signal from the brake pedal to the stop lamps. I guess I'll start at the pedal and look for a place to tie in. Maybe YouTube has a video demonstrating the installation procedure for the controller using this Wiring Adapter. That would be nice too. The price for the item was fair, as was the shipping cost and delivery time. No complaints with any of that. I'd share a picture of the product but actually there's one on the page where it is advertised, the page from which I ordered it. I'm not sure why they want me to "share a picture of my product". As for the problem that it solved for me... I didn't have one. It solved that problem. Now I have one.
Appreciate the installation videos
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...
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.
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
Works but doesn’t totally perform as 2012 stock dodge one.

Thank you for your review. There is not a port to plug a brake controller adapter into on the 2006 Jeep Commander. If the 2006 Jeep Commander has a factory towing package the wires for a 7-way will be ran to the front of the Jeep. You will then use the hardwire adapter part # HA81789-HBC to splice into those wires. You will also need part # 5506 to complete the wiring to the battery. If the 2006 Jeep Commander does not have a factory towing package it requires the 7-way plug to be hardwired. In this case an wiring kit part # ETBC7 is needed. The ETBC7 comes with the all of the necessary wiring to wire in the plug and the brake controller. If the vehicle does not have a factory towing package you may also need a 4-way flat connector if you do not already have one. The 4-way connector is part # 118408 for the 2006 Jeep Commander without towing package. I have attached a video of installing a brake controller on a 2010 Jeep Commander with factory wires ran and a help article for the ETBC7 installation.
