Tekonsha Voyager Trailer Brake Controller - 1 to 4 Axles - Proportional
part number: 39510

Proportional brake controller can be mounted within a 90-degree vertical range. LED monitor indicates braking action of trailer. Fine-tune power adjustment lets you set braking intensity to suit your towing needs.

Features:

  • Brake controller activates trailer brakes in proportion to your vehicle's braking action
    • Automatically adjusts trailer's braking based on deceleration of tow vehicle
    • Activates immediately - no pausing like with time-delayed brake controllers
  • Multiple mounting options
    • Position within 90 degrees in the vertical plane
  • Fine-tune adjustment for braking power and aggressiveness
  • Green LED monitors a secure connection with trailer
  • LED monitor changes color to alert you to braking action of trailer
  • Built-in, slide-bar manual override
  • Plug-in, vehicle-specific brake-control adapter can be used for certain applications to reduce installation time


Specs:

  • Application: trailers with up to 4 axles (8 brake assemblies)
    • Designed for use with electric brakes only
  • Dimensions: 3" wide x 5" long x 1-1/2" tall
  • Mounting: between -20 degrees and 70 degrees in the vertical plane
  • 5-Year limited warranty


Proportional Braking

With a proportional brake controller, you can get heavy-duty emergency braking, general braking or slow-to-an-idle braking for your trailer automatically. The intensity with which your trailer brakes are activated and the rate at which they are applied are dependent on the deceleration of your tow vehicle. This means that, unlike time-delay controllers - which send the same amount of preset power to your trailer brakes every time - proportional controllers are able to adapt to every braking situation differently. So, if you slam on the brakes in your truck, your trailer brakes will activate with that same extreme intensity. And if you merely slow down as you approach a red light, your trailer will gradually brake in the same manner.


As long as the Voyager controller is mounted properly and is pointed in the direction of travel, it will sense - via an internal inertia sensor - how your tow vehicle brakes. This inertia-based sensor responds to the deceleration of your tow vehicle as you brake by signaling the controller to send out enough power to your trailer brakes so that they are activated with an intensity that matches. The result is uniform braking across your towing setup. No push-pull action - just smooth, proportional braking every time.


Power and Sensitivity Adjustment

Getting the braking power you need for your application is simple with the Voyager. First, set up the controller as indicated in the instructions, making sure that the internal sensor is properly leveled. Then set the overall power by adjusting the power knob while you test out your rig. The power should be just enough to achieve maximum braking without locking up your trailer brakes.


Once you have the overall power set, you can fine-tune the power output by adjusting the sensitivity of the internal sensor. Use the level knob on the side of the Voyager to achieve your desired degree of intensity. Move the knob toward you (clockwise) to delay the power output, creating braking sensitivity that is ideal for lightweight setups. If you are towing a heavy load, you may want the trailer to brake more aggressively to prevent it from pushing your tow vehicle. To get more intense stopping action, turn the level knob away from you (counterclockwise).


LED Indicator

On the front of the Voyager there is an LED indicator that is designed to keep you aware of the braking action of your trailer. Typically, this light burns green to indicate that your trailer and tow vehicle are securely connected. When the light is green, only 5 milliamps are being drawn, thus minimizing drain on your vehicle's battery.


As you apply the brakes in your tow vehicle, the LED will change to red. This indicates that power is being sent to the trailer brakes. The light will also burn red whenever you activate the manual override lever.


During installation and setup, this light is 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.


Correct Voyager mounting90-Degree Voyager mounting

Note: The Voyager must be mounted on a level horizontal (side-to-side) plane and must be lined up with the direction of travel for the internal sensor to function properly.


Once the controller is mounted, you must level the internal sensor. First, set the overall power to 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.


Installation requires that you either purchase a custom wiring adapter designed to plug into the Voyager or that you hardwire the controller directly into your vehicle. To hardwire the Voyager, you must remove the plug at the end of the integrated wiring harness.


Installation Accessories

For 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


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.

This was a fairly easy install and has a wide range of adjustment if your mounting level is not perfect. It has worked perfectly for a year and I am able to swivel it up and out of the way when I don't use it so it has no interference. Very happy with the adjustability of the unit and gives you piece of mind when we are towing a nearly 4000 lb trailer with a 4000lb SUV. 837232

Received this yesterday and was able to install it today. Instructions were very easy to follow and the only problem I had installing it was contorting myself to install the bracket. Once I got the bracket in place the rest was a piece of cake. Went for a test drive as the instructions suggested and did have to tweak it a little but it's doing exactly what I expect it to do. I'll be hauling a John Deere Tractor and wanted to make sure the brakes on the trailer worked. 853184

I have had several of these over the years. I currently have 3 controllers on different trucks. I pull 5 different trailers with completely different weights. The controller works really well. I definately recommend this controller. You level it on the left side, which allows for placement in alot of areas of the truck. When I am towing I can adjust the brakes with the dial on the right side. Obviously the brakes need to be lighter when the trailer is empty. Simply turn the dial back until the brakes don't lock up. When I get it loaded I turn the dial forward until I can feel the brakes take hold. The lever on the front lets me manually apply the trailer brakes. I use this in cases where I am going downhill and it is better to let the trailer slow me down. If I ever need another controller, this will be it. Great price also. 92292

Completely plug and play installation and works flawlessly, very happy with this unit. I also ordered the exact harness for my 2005 f150 with tow package. Here are a couple of hints that may be helpful. My installation also required a 30 amp cartridge fuse to be installed in the fuse panel in location #105(electric trailer brakes) under the dash on the passenger side. I also installed a relay in location r05 (trailer tow battery charge) but I don't think this is needed for the controller to function. I still had the original trailer brake kit and it had the additional fuse panel instructions and the relay. The owners manual showed where the 30 amp fuse and relay plugs in. You cannot test this unit until a trailer with brakes is connected, ie the led will not light up until it senses a brake circuit. 272082

This installation is in a 2010 Ford F-150 Lariat The installation was very easy. It helps to have a 90 degree screwdriver to install the screws on the right side. The screws will install easier if you install them first, remove them and re-install after the bracket is installed on the vehicle. 8161

The break controller was what I ordered but the wire harness that was sent with it did not have a wiring diagram so I could wire it to my truck correctly. I had to go to a YouTube video to get the correct information so I could wire the harness to my truck without hurting the controller or the vehicle. Question: Does your company not send a diagram with all of your harness? Customer should not have to go to a YouTube video to install the product. 406364


Comments
Hi Walter and Donna, since brake controller wiring harnesses are not universal, manufacturers do not provide wiring diagrams in their packages because they do not know how or if your specific vehicle is prepped for a brake controller. However, we do have a help article on brake controller wiring, and general trailer wiring. I have included links for your reference. If you have any other issues do not hesitate to contact our tech experts.

We do not have any instructions for this item either, but I do a help article that explains the details of how to install this item. This is a hard wire application for Draw-Tite or Tekonsha branded brake controllers, this is where the black plug end will install. The loose wires will then be connected to the corresponding functions on the vehicle: Blue: trailer brakes White: vehicle battery negative terminal Black: vehicle battery positive terminal Red: cold side of stoplight switch

The controller works fine but it has developed a rattle on rough roads. It was a replacement for one I broke. 559720


Comments
The Voyager brake controller is an older design that uses a pendulum-style accelerometer, versus one thats solid state. This is the rattle youre hearing.

I pull a small camper with a VW Touareg. The electronics in the T'reg don't play well with top of the line brake controllers. I spoke with the Tekonsha rep and he recommended the Voyager. The Voyager is a very simple controller, easy to install, and works well. I don't miss the fancy display. ICS 271698
