Specs:
The Syncronizer applies your trailer's brakes when the brake pedal in your tow vehicle is engaged. Every time you apply the brakes in your Ford F-150, 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 you have set. The amount of braking power can be adjusted to suit your preference. To determine the amount of power that is best for your application, you must test out your towing setup and choose what feels best.
A time-delay controller is so named because there is a delay between the time that you initially apply the brakes in your tow vehicle and the time that the controller reaches the set maximum power output. Unlike a proportional brake controller, which activates your trailer's brakes based on the deceleration of your tow vehicle, the Syncronizer sends power out in the same way, with the same user-set delay, no matter the braking situation. The controller will continue to send out power to the trailer brakes as long as your foot is on the brake pedal, even when your truck and trailer have come to a stop.
The diagram above shows the controls and components of the Hayes Syncronizer electric trailer brake controller.
The power output control 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, use the thumbwheel on the left front of the Syncronizer to adjust the output. To get more power to your brakes, rotate the dial upward. To decrease the power output, move it downward.
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.
The manual slide lever overrides the preset power output and allows the operator to engage the trailer brakes without using the vehicle's brakes. In addition to being a necessary safety feature, this option helps to control trailer sway by slowing the trailer to put it back solidly behind the tow Ford F-150.
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 inertia plays no role in the functioning of this controller, you do not have to mount the unit at any particular angle or position it in any particular direction. As a result, mounting options are limitless, so long as you can still easily access the manual override.
Installation of the Syncronizer requires that you either purchase a custom wiring adapter designed to plug into the controller or that you hardwire the controller directly into your Ford F-150. To hardwire the unit, you must remove the plug at the end of the integrated wiring harness.
Installation Accessories
The Hayes vehicle-specific, dual-mated wiring adapter is available for most newer trucks and SUVs with tow packages. One end of the custom adapter plugs into your Ford F-150's brake controller port, and the other end plugs into the controller - no hardwiring required.
Hayes also offers a universal wiring harness (HA81789-HBC - sold separately) that plugs into any Hayes brake controller. The 4 leads on the universal harness can then be hardwired into your Ford F-150. By splicing the universal adapter into your wiring instead of directly connecting the brake controller to your wiring, you gain the ability to unplug and remove the controller from your vehicle should the need arise.

This brake controller is going to activate your trailer brakes with preset intensity. Then a signal is sent to the trailer brakes when the tow vehicle's brakes are activated.

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. 243611
