Built-In Controls on the Syncronizer
Power Output Control
Braking output is the maximum amount of power that will be applied to your trailer's brakes. How much braking output you need is determined by the weight of your trailer; a heavier trailer will need more power to bring it to a stop. You want to set the braking output as high as you can without locking up the brakes. Once you've set up the brake controller the first time, you shouldn't need to adjust the settings until the trailer load changes, you switch trailers, or road conditions change. Use the thumbwheel on the left of the module to change your settings.
Red Indicator Light
The red LED indicator light illuminates when the trailer brakes are applied. This light glows brighter as the power output to the trailer brakes increases.
Slide-Bar Manual Override
The Hayes Syncronizer 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 lever 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.
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.
Installation Accessories
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, a 20-amp circuit breaker (sold separately) may be required for installation.
Time-Delayed Braking
The Hayes Syncronizer 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 Syncronizer. 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. The amount of braking power (output) 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.

This time-delayed brake controller has a straightforward design that makes it easy to use. Includes an LED indicator and manual override. Activates brakes with a preset intensity.by: Benjamin08/22/2023
Super easy to install and the additional information they provided for my specific vehicle made it possible for me to have every piece necessary for a seamless installation.
by: Lawrence 09/07/2023
Splicing the wires was no problem. Instructions were good. The only recommendation that I will give is that you trash all screws with flat screw driver heads. I also opted for bolts, nuts & washers for attaching the bracket.
by: Ed09/13/2023
I think it will be a good brake controller, I have not had a time delayed on before.
by: Jonas08/04/2023
Installation was simple and straightforward. Took less than 30 minutes from start to finish.

Looks good!
by: Nick 04/24/2023
Fit perfectly. Followed instructions and it works as it should. Great product at a great price.
by: Bob P.04/10/2016
Original supplied item was defective, however Hayes customer service immediately sent another unit and it works great. With the addition of a small removable slip in bracket for the console of my 2012 GMC 1500 Crew Cab and the wiring adapter, I can simply plug and play when I need the controller as opposed to a permanent installation that I have in my other pickup.
by: Dylan 04/10/2021
Works well. I like the delayed brake activation, it seems to be a smoother transition. The custom harness makes installing this controller easy and FAST. Love buying Made in the USA products and etrailer.com has a lot of them.
by: Frank 11/16/2019
easy to install. Brakes tested good to trailer. I used self taping screws to mount brackets, rather than the bolts and nuts that it came with.It was to difficult to get my hands in position to use bolts and nuts (no big deal).

deliverd on time. and plugged right in thanks
by: Dave 2018 ram 1500 eco 04/07/2019
Installed in 10mins in 2018 ram 1500 ecodiesel, have not used with trailer yet. Seems good for price, mounting bracket could be made a little better. Good service from e trailer
by: Dylan 09/26/2021
This is the 2nd one of these I’ve bought. I like the time delay application to the brakes. Always will try to buy products made in the USA. The price went up since I bought this same controller 1 1/2 years ago.
by: Gary03/19/2015
Good controller at a good price. Works as expected. Fast shipping at standard rate. This controller was installed in an 08
Sprinter camper with the help of the on line video from etrailer.
Thanks,

Installed in 10 minutes. Works excellent and combined with the wiring adapter was a simple plug and play.

The trailer seems to be holding up just fine. It was a good investment for my small business and I'm thinking about buying another from you.

- Wiring Colors for Kelsey Hays Brake Controller 81739Your old Kelsey Hays brake controller uses the standard wiring colors for brake controller install. The red goes to the stoplight circuit, the black goes to the 12 volt power supply, and blue goes to the trailer connector as it's brake output.
view full answer... - Is it Normal for Brake Controller Light to Stay On When Not in UseBrake controllers don't have an off switch and are designed to go into a sleep mode after 15 minutes or so of inactivity. It sounds like your controller is wired up correctly in your 2009 Chevy Silverado and the controller just hasn't gone to sleep yet. You wouldn't want to just unplug it as that will cause it to lose it's user settings.
view full answer... - Why Does Hayes Syncronizer Brake Controller HA81725 Not Light Up When Pedal is PressedThe display on the Hayes Syncronizer Trailer Brake Controller # HA81725 should illuminate both when you press the brake pedal and when you use the manual override lever. If it does not light up when you press the brake pedal then either there is a problem wit the red wire's connection to the brake light circuit or you have the power set so low that the display does not light up. The controller will apply full power with the manual lever but with the brake pedal it will illuminate only...
view full answer... - Uninstalling Hayes Syncronizer Brake Controller From 2014 Ford ExplorerTo disconnect the Hayes brake controller you can simply unclip the wiring connection behind your trailer brake controller and tuck it out of the way. Then you can remove the brake controller from it's mount and either discard it or sell it. It will not in any way effect the braking on your vehicle. It only captures the brake light signal and then sends power to a trailer with brakes. Removing it will have no impact on your vehicle but only on your trailer towing ability.
view full answer... - Red Light of Hayes Syncronizer Comes on When Applying Brakes with No Trailer ConnectedYes, the red light on the Hayes Syncronizer Trailer Brake Controller # HA81725 will come on whenever you apply your tow vehicle's brakes, even when no trailer is connected. However, no power is used when there isn't a trailer detected.

- No Brake Lights on 2001 American Coach American Tradition MotorhomeI would love to help but I don't have any diagrams of your motorhome if that's what you're thinking. If the lights aren't working right, you need to check and trace wires, no two ways around it. In short, use a circuit tester and check for power at the trailer pin. If there's no power on said pin, find what wire controls it and start tracing it back until you find the break. I don't have any wire color guides as they can vary from vehicle to vehicle I have attached a general article below...

- Will Hayes Sincronizer Trailer Brake Controller Fit on a Honda Goldwing MotorcycleYes, the Hayes Syncronizer Trailer Brake Controller # HA81725 is a good choice with your Honda Goldwing. A time delayed controller is a better choice on a motorcycle because of the limited space for installation. A proportional controller has more limitations as to how they can be mounted which will be an issue on a bike. Also, the leaning of a motorcycle while turning will tilt the controller and a proportional controller cannot function this way. To connect the controller to the bike's...

view full answer... - Will Hayes Syncronizer Brake Controller Work on a 2016 Ram 1500In the newer Rams the stoplight switch of yhe truck uses a lower voltage signal than most vehicles so only some controllers can be used.
