Electronic controller activates electric trailer brakes with a preset intensity when you apply the brakes in your vehicle. Digital display, manual override, and a simple, plug-in port included. Power output and braking aggressiveness are adjustable.
The Activator III applies your trailer's brakes when the brake pedal in your tow vehicle is engaged. Every time you apply the brakes in your vehicle, a signal is sent - via the brake switch - to the Activator. 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 (sync) can be adjusted to suit your preference, the road conditions, type of trailer and size of the load. To determine which levels are 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 maximum power output. Unlike a proportional brake controller, which activates your trailer's brakes based on the deceleration of your tow vehicle, the Activator sends power out in the same way, with the same gradual delay, no matter the braking situation. Although this delay always exists, it can be adjusted by changing the sync setting.
To adjust the aggressiveness of your trailer's braking action, use the slide control on the side of the Activator III to change the sync setting. If you want to reach maximum power output faster, move the switch forward. To get smoother braking action, move the switch backward, thus supplying power to the trailer brakes more gradually. You can alter the sync setting to suit your driving preferences or to improve handling based on changing road conditions or varied trailer loads.
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. As a result, mounting options are limitless, so long as you can still easily access the controller. After mounting the unit, hardwire one end of the included pigtail harness directly into your vehicle. The other end plugs into the brake controller.
For even easier installation, a vehicle-specific wiring adapter is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.
Note: If a custom brake-control wiring adapter is not available for your vehicle, one of the following will be required:
20-Amp circuit breaker (9506P - sold separately) for 2- to 4-brake applications
30-Amp circuit breaker (38630 - sold separately) for 6- to 8-brake applications

Install your electric brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in harness beneath your vehicle's dash.
This adapter plugs into the connector beneath your vehicle's dashboard. To reach the connector, first locate the notch in the access panel in the center of the dash, near the passenger side. Using a trim panel puller, carefully pry the panel out and undo the locking tabs to remove the panel. You will find the mating connector behind this portion of you dashboard.
To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.
This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.
