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.

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.
