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 (sold separately) 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

The Tekonsha Voyager trailer brake controller works well in my 99 Silverado 1500, which was easy to setup for my trailer. The option to allow for different settings of aggression for the trailer braking has allowed the stopping with different loads to be graceful with the turn of a knob. Decided to install the controller in CD storage with velcro for a nice look. Easy access when in place during use for easy observation and twicking during operation. The wife can assist with the twicking while I am driving. Excellent product!

The Voyager unit has been working flawlessly this past year. Excellent product that keeps on working!

etrailer makes the purchase easy. I have always used Tekonsha Voyagers, and on my new truck (2015 Silverado) I also wanted the convenience of having the plug and play wiring harness. etrailer had exactly what I needed and was very easy to find on the website. Installation was flawless and clean thanks to the good hardware supplied. Very excited to put some trailers behind the truck with the stopping power confidence that comes with the Voyager.


Comments
Working great! The mandatory leveling process was successful and the unit functions as intended.

This was an easy install on my 2019 GMC truck using the appropriate wiring adapter. Instructions for setting up the control were clear. After a few adjustments my trailer brakes worked as they should. Minor adjustments of the controller are needed from time to time, but overall the controller is reliable. Good value.


Comments
The brake controller continues to function without issue.

Not even 2 years after install all rusty. Electric brake pin broke due to rust.
Impossible To remove 4 bolt holding connector due To rust. I do not recommend




by:

Good break controller. I used it in my new 2022 Chevy Colorado that did not come with a break controller. On my truck it does require purchasing a separate plug / harness and wiring it into the truck. Then you plug this into the other harness.




by:

Last year I traded my Silverado for a Yukon to tow my 21’ camper. The hitch tube was integrated into the Yukon bumper and those 20” wheels raised the tube height 7”. I purchased your 13” drop shank to level my hitch/camper connection but experienced trailer “sway” because of that long shank. I fabricated a set of “sway bars” to tame that movement. Now I can tow my camper safely. Thank you for making this long drop shank available for taller tow vehicles!




by:

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.




by:

Difficult to adjust. It would grab too hard, so I would adjust the power and/or level down, then the trailer was pushing me. Adjust up, then it grabbed too hard again. After a few months of very light use, it started grabbing very hard even with the power and level turned way down, although that may have had something to do with the fact that water got into my 7-way plug and made the controller come on when nothing was connected. I strongly recommend upgrading to the primus or other model with digital voltage display and boost function. I have a primus now, and it performs much better.




by:

Very easy to install. Mounted on lower dash and ran the harness under dash tucked away with some zip ties. Everything was plug n play into factory harness on a Nissan Titan So far works as should , have about 20 hrs trailing use. I would buy again

This is my second Tekonsha; I had to replace my 10-year old one after I accidentally broke it.

This one is a bit of an upgrade, and is easily able to lock up the disc brakes on my 15,000 lb trailer. Adjusting it properly, I'm able to brake as though there were no trailer at all. Set it, and forget it. It doesn't get any easier than that.

Installed in my 2018 Silverado Custom. I ordered the additional wiring harness and the install took less than thirty minutes. Plug and Play at its simplest. Thank You etrailer.

The product was easy to install with the help of the F-250 adapter. I followed the direction and the product worked just as it was advertised from etrailer.com. If I had to give the Tekonsha Voyager Trailer Break Controller a star rating from 1-5, I would give it a 4.5.




by:

I've put a half dozen of the Voyager controllers in different trucks over the past twenty years, the only controller I will use. They're great.




by:

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.




by:

Wasn't a replacement as much as a new install but worked perfectly on my 203 Avalanche after finding the right video which explained the additionally connection near the fuse box.




by:

I was looking for a basic controller to activate the trailer brakes on my Rockwood 276HW pop up, after spending an excruciatingly stressful weekend adjusting brakes/bearings. I found it w the Voyager which, with the previously reviewed harness/connector, attached to the built in connection on my 2020 Tacoma flawlessly. A no-surprise product with the installation made easy w thorough instructions. Brakes work great. Very happy!




by:

your company provide me excellent products all time .
this is the great company.
congratulation .




by:

Excellent product, install went great following the video on etrailer.com. Shipping took longer than estimate at checkout, but still made it. And just having it in stock made etrailer better than my local store, which did not.




by:

I have a 12 ton backhoe pro trailer it has 4 short axles 2 on each side. It does not have dual wheels. It has 8 wheels with 8 sets of brakes so I needed a controller for 4 axles. This controller has worked well the settings are a little touchy but it works great. My truck is a 4 speed and i usually have the controller set so if I let off of the gas like coming to a stop the controller slows the whole rig without touching the brake. I like the indicator light to see what it is doing and that it is connected right




by:

Hard to adjust. Had tech at rv place adjust still grabby. Should have got more modern controller




by:

Always great service for my trailer nee ds




by:

Provides braking as advertised. The mount is a bit obtrusive and permanent. If you're looking for a smaller form-factor or the ability to move between vehicles, look at more expensive models.




by:

Definitely was surprised with a base model controller. I ordered the product and it arrived much sooner than I expected with the correct wire. Very satisfied. Will be trying it out very soon.


Comments
It works well. No issues 1 year in.

This controller is outstanding in how easy it is to setup. I upgraded to this model after I had wiring problems with a less expensive unit. etrailer staff was outstanding in their support helping me with that problem and allowing me to upgrade to this controller.

  • Green Light on Tekonsha Voyager Stays On with Trailer Connected and Truck Turned Off
    The Voyager brake controller # 39510 should go to sleep after about 15 minutes of it not sensing any movement. If you park and turn off the truck and come back after 15 minutes, look in the window and the light should be off. But even if it does not turn off the controller in this state is only drawing 5 milliamps current from tow vehicle. It would take over 10,000 hours to drain the tow vehicle battery at that rate.
