Power and Sensitivity Adjustment

Once the brake controller is installed, you can use the knob on the right side of the unit to adjust the gain (also known as output). Gain lets you set the maximum amount of power that will be applied to your trailer's brakes. You want to set it as high as you can without locking up the brakes. Typically, this setting is only readjusted when you experience changing road conditions or if you switch over from a heavy, loaded trailer to a much lighter, empty trailer, or vice versa.

Tekonsha Voyager

You can fine-tune the gain by adjusting the sensitivity of the internal sensor using the knob on the left side. This controls the aggressiveness of your trailer's braking, meaning how quickly the brakes reach the maximum braking level. You can adjust this when you're towing heavy loads and you need more umph to bring your trailer to a stop. Your tow vehicle doesn't need that much power to brake in time, but your heavy trailer does. A high sensitivity level will get the braking power to your trailer brakes faster and with more intensity so that it doesn't push your tow vehicle forward.

LED Indicator

Keeping with its simple design, the Voyager will not overwhelm you with information. An LED indicator on the top of the unit lights up green to show that your trailer is securely connected to your tow vehicle. The LED indicator will change to red when the brakes on your trailer are activated.

During installation and setup, this light is also used to ensure that the Voyager will be able to function correctly. Proper leveling of the internal sensor is crucial to the operation of this brake controller. When the sensor is level, the LED will change to a shade of orange.

Simple Installation

The Voyager is designed to be mounted in your cab at a vertical angle that is between -20 degrees and 70 degrees. The brake controller needs to be horizontally level and parallel to the direction of travel in order to function properly.

To connect the Voyager, hardwire the included harness to your vehicle. For a plug-and-play installation, a vehicle-specific wiring adapter (sold separately) is available for select vehicles. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

Once the controller is mounted and connected, you must level the internal sensor. First, set the overall power to the maximum using the knob on the side of the controller. Then, while pressing the tow vehicle's brake pedal, adjust the level knob on the other side of the brake controller (this is the same knob that is used to fine-tune the power output) until the LED monitor is a shade of orange.

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

Proportional Braking

What is proportional Braking

The Tekonsha Voyager brake controller comes equipped with proportional braking to give you the best towing experience. Proportional braking means that your trailer brakes mimic your tow vehicle's brakes. If you slam on the brakes in your vehicle, your trailer brakes will activate with the same intensity; if you brake lightly, your trailer brakes lightly too. The trailer's braking is in proportion to your vehicle's braking. This saves wear and tear on the tires and the brakes on both your vehicle and trailer.

The Voyager uses a pendulum system to sense how your vehicle is braking so it can send the right amount of braking power to your trailer. It measures the inertia of your tow vehicle and activates the trailer's brakes to slow at the same rate. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.
