Built-In Controls for Adjustable Power

Hayes Engage Controls and Components

Braking Output

During the initial setup process, use the adjustment buttons on the left front of the Engage 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. To view the output setting, press either button and release. The output setting will appear as a percentage on the digital display - from 10 to 99. Use the plus and minus buttons to raise or lower the setting in increments of 5.


Power Ramp Time Setting

To adjust how aggressively the trailer brakes activate, press and hold the minus button until the display flashes, then release. The power ramp time (1-5 seconds) will flash. Use the minus button to cycle through the options. If you want to reach maximum power output faster, select a lower number. To get smoother braking action, select a higher number. When the desired ramp time is reached, press the plus button to select it. You can alter the ramp time setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads.


Manual Override

The Hayes Engage keeps the manual override within easy reach on the front of the module, great for stopping sway or controlling your trailer's momentum in emergencies. Push the slide-bar to 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.


Hayes Engage review

Quick, Simple Installation

Because inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle. Your mounting options are limitless, so long as you can still easily access the controller and manual override.


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.


See also 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.


Note: If a custom brake control wiring adapter is not available for your vehicle, either a 20-amp or 30-amp circuit breaker (sold separately) may be required for installation.


Time-Delayed Braking

What is time-delayed braking

The Hayes Engage comes equipped with time-delayed braking. Every time you apply the brakes in your vehicle, a signal is sent - via the brake switch - to the Engage. The controller then sends power out to your trailer brakes to activate them with an intensity set by you, at a rate determined by you. Both the amount of braking power (output) and rate of application (power ramp) can be adjusted to suit your preference, the road conditions, the type of trailer, and the weight of your load. To determine which levels are best for your application, test your towing setup and choose what feels right.

After one year of use the unit works as advertised but does require some getting used to.When first installed it goes to 25% activation in a total of 5 seconds so I turned it down to 15% and like it better loaded or empty..I prefer a proportional controller over timed but due to shortages at the time of purchase this one has filled the job well..Good price and easy install so will see how long it lasts...



by:

Easy install and works great. I get all my trailering items from etrailer and have never had an issue.



by:

Shipment was prompt and I received exactly what I ordered. Super easy to install in my 2005 Dodge Ram 2500 and im a girl. :)



by:

Very good company to deal with will tell others about your great company



by:

Packaged well, came 1 day earlier than expected. Exactly what I ordered.



by:

Nissan Titan pulling a fully loaded 14x7 Cargo Mate Blazer enclosed trailer. The unit was pretty easy to install. etrailer included the proper wiring harness for my Titan. It is not difficult to find the proper brake setting for the load size and not hard to tweak on the fly. This unit worked like a charm while hauling this large load about 1000 miles. So far it has been worth every penny and I got it at a great price!

I have not pulled my trailer since I helped some friends move back in February, but the harness was still working well at the time.



by:

Great. Easy



by:

Easy to install as I also ordered the wire adapter kit for my truck. Installation was quick and the unit works as I expected. Good investment for safety. Between the phone help with the ordering of the wire adapter kit and You Tube, it took me longer to watch the videos than it actually took to install it.



by:

Hayes trailer brake controller, custom wiring adapter, power cord adapter, andersen camp leveler, trailer leveler. All of these items were delivered in a timely manner and as advertized. Will probably order other items in the future.



by:

Good product, easy fitment into factory Ford storage cubby. Small hole in back of cubby made to allow wire harness to pass through.



by:

I have not had a chance to use the brake controller yet. I did get it installed today. The installation was easy.
The only thing that I might say is that the set up information was not very clear. It seems like there should be a notation somewhere in the set up about how long the lights are going to flash when there is an OC readout on the unit or how to stop the flashing. Maybe I missed something in the instructions.



by:

The website was easy to work with. When I needed help I was able to reach someone immediately and they couldn’t be more helpful. The items arrived earlier than expected. Installation was straight forward and works like it should. I would recommend using etrailer for all your towing and trailer needs.



by:

this is the best for the money you can buy,I deleted one star because the info on color codes as relates to my 2022 gmc makes it difficult to match color codes with the truck. neither kelsey or gm are great at this identification, particuly in terms of battery/ grounds/ signal /trailer brakes/ etc



by:

This was a replacement purchase. The original failed at 8 years old. The original started flashing the brake lights every 5 seconds while turned off and parked. Every thing fit back in the original spot. I have not tried the function with a trailer on.



by:

I purchased this item, didn’t read enough to know I needed an adaptor to fit my Chevy Silverado. Cut the wires and spliced them into my Chevy pigtail provided. Thought the item was not working. Called in and was told someone would call me back the next day with instructions. As told, a representative call me and advised me that Chevy has a different color code. After a quick change everything was functioning as hoped thank you e trailer



by:

Works perfectly! Great service.



by:

It’s easy to adjust to get the brake controls. I have a 26 foot filth wheel camper and it makes it easy to stop in the event of emergency.



by:

This controller was so easy, mounting it under the dash, put in the 40 amp fuse. And the controller was ready to go. Install time was less than a hour. That included going to the parts place and getting a fuse. I am very happy



by:

works very well with my 28 ft trailer....easy to install...fit nice in the cuby hole ...with a little mod.... on the lower left side of my dash......looks factory



by:

I love it, I have one in both of my trucks. It works on single & double axle brakes., you can adjust the delay & see what you set it on and don't have to guess what it is on. Very easy to adjust brakes for your loads, there again you can also see what you have it set on also. My neighbor used one of my trucks to haul a load hay & loved it . Asked me to order him one for his truck.



by:

we had used this controller in the past, and the new one plugged right in for us



by:

Directions were perfect. Never wired a truck for trailer control. Got it right the first time.



by:

Easy install and works great. No complaints here.

See what our Experts say about this Hayes Trailer Brake Controller

  • Hayes Engage Trailer Brake Controller Shows bF Error Code
    The error codes shown on the Hayes Engage Trailer Brake Controller part # HA81760 can be easily deciphered by looking at the owner's manual. Per the manual, "bF" indicates the blue wire is connected to wrong place, short in wiring / connector, faulty or disconnected breakaway switch. The blue wire is the brake output wire that runs from the brake controller to the 7-way and then from the 7-way to the braking assemblies. Therefore, I recommend tracing this wire to ensure there are no shorts...

  • Troubleshooting Hayes Engage Brake Controller Showing BF Error Code
    According to the operating instructions (I'll email you a copy) the bF error code indicates that there's a short somewhere in the brake output circuit, which is the blue wire that exits the rear of the controller and delivers the voltage to the trailer brakes through the trailer connector. Several things might be causing this. The first thing you will want to do is sever the blue wire from a few inches behind the brake controller. Leave enough wire so you can reconnect it later. Then use...

    I spoke with my contact at Hayes about you installing the Hayes Engage # HA81760 and Custom Wiring Adapter # HA81797-HBC on your 2014 Ram 1500 Sport. Although there isn't really a specific or recommended route, my contact did say that a lot of people he talked to like to run it along the door frame. To do this you will simply want to push the red wire in to the molding along the bottom of your door frame. This should be a great way to route the wiring around any electronics and give it...

    Hi, and yes, the Hayes Engage Brake Controller # HA81760 with Wiring Adapter # HA81789-HBC is compatible with your 2003 Toyota Tacoma.

  • Troubleshooting OC Error Code on Hayes Engage Trailer Brake Controller HA81760
    With the Hayes Engage Trailer Brake Controller # HA81760 the code OC indicates that the controller does not sense an electrical connection to the trailer brakes, or that the trailer has electric-over-hydraulic brakes which do not work with this unit. Since you also have an issue with your tail lights staying on the problem is almost surely corrosion inside the trailer connectors. Corrosion can build up inside a vehicle's socket and inside a trailer's plug and sometimes it is hard to see...

  • Inexpensive Brake Controller that Works with Electric Over Hydraulic Trailer Brakes
    Only certain brake controllers are compatible with electric over hydraulic trailer brakes. The lowest cost option that is compatible is # HA81760. But if it were by I would use # 90885 because it is easy to set up and it is reliable. If your existing brake controller works fine with regular electric trailer brakes then installing a new controller will be easy since brake controllers have the same 4 wire functions: white is ground, black is 12 volt power in, red is input from the brake...

  • Installing A Brake Controller In A 2019 Ford Ranger
    Your answer depends on what connector you have. If the Ranger has a factory-installed 7-way it should have a standard brake controller connection port above and to the left of your left knee when seated; this will be near the kick panel. If the truck instead has a factory 4-pole harness, under the dash there will be three blunt-cut wires, blue, yellow with red tracer and white with purple tracer each for the controller output, the 12V power input and the brake light switch wire.

    The first thing you will want to do is use a circuit tester like the Circuit Tester part # PTW2993 in order to test the stop light switch wire on your vehicle's brake pedal while the brake pedal is depressed. You will need to be spliced into the wire that only has power while the brake pedal is depressed. If the wire is receiving power, then the brake controller is faulty and will need to be replaced. If the wire is not receiving power, then you will first want to check the stop light switch...

Some models will require a wiring kit to run wire to the battery, so if you're not getting power when the controller is plugged in, you'll need to use part # 5506 which includes 20, 30, and 40 amp breakers.
