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

This proportional brake controller is designed to keep towing simple. Includes an LED braking indicator, a slide-bar manual override, and a knob to adjust braking power. Mounts easily within a 90-degree vertical range.

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
  • Simple controls keep your settings within easy reach
    • Gain setting lets you adjust the amount of power sent to the trailer's brakes
    • Slide-bar manual override allows you to control trailer sway or stop in emergencies
    • Sensitivity knob lets you set initial braking power and aggressiveness for smooth, safe braking
  • Green LED on the top of the module monitors a secure connection with trailer
    • Glows red to indicate that trailer brakes are being activated
  • Quick and easy installation with included bracket and hardware
    • 90-Degree vertical mounting range - must be horizontally level and parallel to direction of travel
    • Plug-in, vehicle-specific brake-control adapter available for select vehicles to reduce installation time


Specs:

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


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.


Correct Voyager mounting90-Degree Voyager mounting

To connect the Voyager, hardwire the included harness to your vehicle. For a plug-and-play installation, a vehicle-specific wiring adapter 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.


Installation Accessories

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.


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.

I am very satisfied with the Voyager brake Controller I purchased. It is the easiest unit to adjust that I have ever owned. The controls are easy to adjust and it has worked well with my trailers.



by: Corey M.08/01/2020

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.

by: Gary12/26/2020

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!



by: Robert G07/15/2016

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: Wayne12/20/2019

The drawtite hitch and trailer wiring harness fit great. Instructions were clear and concise. Installation was a breeze. I am ready to tow my little trailer now. As soon as I get the brake controller installed, I will be ready for my big trailer.



by: Mark01/04/2020

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.



by: Chris C10/09/2016

If your truck comes with the tow haul package.... this item is literally plug and play. I had it wired up and all mounted inside of thirty minutes. It's literally 4 wires and the stock system wires are labeled along with the brake contoller. I haven't tested it yet but so far I am thoroughly impressed!



by: Easy install01/21/2021

Perfectly wired directly to existing wiring that I had for the previous brake controller I replaced with the, Draw Tite I Command. This will make it a lot easier should I choose to upgrade the unit in the future.
Fantastic customer service from Joshua as well.



by: Alfie07/30/2020

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.

Ram 2500

I installed the Curt gooseneck on my 1993 GMC 2 Wheel Dr. 2500 truck. All the components have tight tolerances. It took me eight hours. With a socket and the wrench. Laying on my back. I did have to cut the wheel well lip about 3/8 of an inch off because I could not get that front angle bar to slide in without hitting it, no way around it unless you lift the bed up and I wasn’t going to do that!!. You have to cut it.instructions do not state that. I’m very happy with the Hitch, it is definitely stout! I did have to make a notch on the outside brackets to go over my airbag bolt. I also had to remove the support bracket on the inside of the frame for the airbag and the crossmember for the spare tire to get the front angled bar in.



by: Jake 08/20/2021

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.



by: Alex 05/01/2024

Plug it in and voila!



by: Douglas08/03/2023

As always, etrailer delivers. Part was on time and a perfect match for the brake controller. What you don't get from Amazon is the technical support on how to install or use the equipment purchased from etrailer. That's why I keep coming back!

My truck was stolen and wrecked. I was able to retrieve the Tekonsha Brake controller from under the Dash board before it was hauled to the salvage yard, but not the wire harness. I was ale to order a replacement harness from eTrailer and reinstall the controller in my new truck. I had no problems at all. Thank you eTrailer for the great support.

Still works perfectly after one year. Actually, I been using this Controller for well over a year. I just reinstalled it in my new truck a year ago.



by: Walter Calloway05/24/2015

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: Chad07/13/2021

Works as intended, but the plug on the back of the controller is a loose connection. Sometimes I would go to brake and find that I had no trailer brakes because the controller lost power. After a wiggle it would start to work again. I was able to shave the Molex plug a bit and now I don't have any problems with it.

  • How Do I Install A Hopkins Brake Controller In My 2010 Chevrolet Silverado 1500
  • Depending on if your 2010 Chevrolet has the factory tow package or not there is a few things you will need. If you do not have a factory tow package both Tekonsha controller # 39510 and Tekonsha wiring adaptor # 20127 will work for you. If your vehicle has a round plug with a cap instead of a bundle of wires above the spare tire you would need the 7 way plug # 30955 instead. If you do have the factory tow package all you will need is the controller # 39510 and adaptor # 20127. Below

  • How To Adjust Braking Power With Tekonsha Voyager Trailer Brake Controller 39510
  • The right wheel on the Tekonsha Voyager # 39510 you have in your 2006 F-150 is what controls the power sent to the brakes on your trailer, so you will need to hook up to your trailer and go to a parking lot and at around 25 MPH apply the brakes in your truck to see how much braking power is being sent. If the brakes on the trailer are locking the wheels up you need to reduce the gain by rotating the right wheel, and if the trailer does not feel like it is getting enough power to the brakes

  • Troubleshooting Trailer Brake Controller Indicator Light When Connected To Trailer Without Brakes
  • On your Tekonsha Voyager Trailer Brake Controller # 39510, there should only be a light if the controller sees connection to the trailer. This connection to a trailer is found through the pin at the 5 o'clock position on your 7-way, so the controller sees a power draw on the blue brake output wire. This is an issue because the brake controller will sent output power through that blue wire when it reads a trailer is connected. For a trailer without brakes, the light should not come

  • Recommended Wiring For Brake Controller In 2007 Lexus GS430
  • There is not an adapter harness for your 2007 Lexus GS430. To hardwire this controller to your system you can use the Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite Brake Controller 12" Long # 20127 to allow you to use the controller between two vehicles with the quick disconnect. I don't see the wiring needed for your vehicle to use a brake controller, so you will need to do some custom wiring. If you don't have a 4-way flat connection, I recommend the ZCI

  • Which Brake Switch Wire to Use to Install a Brake Controller in a 2017 Dodge Grand Caravan
  • The brake switch wire you will need on your 2017 Dodge Grand Caravan to install the PowerTrac # 39523 is the white wire with a green stripe. It should only have power when the brake pedal is pressed and not at any other time. The vehicle tail light circuit cannot be used because the brake signal is not the only circuit on that wire. I have linked a video that will help.

  • Brake Controller Recommendation for 2013 Ford Edge
  • There is one other part you will need so you can install a brake controller to your 2013 Ford Edge, the Universal Installation Kit for Trailer Brake Controller # ETBC7.

Once you have all of this installed the brake controller I recommend for your 2013 Ford Edge is the

  • Trailer Brakes Only Working With Manual Override on 2011 GMC Sierra
  • If your trailer brakes are only working when you apply the manual override the issue is commonly the red wire - the stop light switch. Make sure it is connected to the circuit that that only sees voltage when the brakes are applied. The issue with not displaying numbers does make me think that the brake controller may have hit the fritz and need to be replaced though, and this would be true if the numbers never display, even when using the manual override. For your 2011 GMC Sierra a

  • Recommended Wiring Harness for 2018 Buick Enclave and Tekonsha Brake Controller
  • For your Tekonsha Brake Controller, the custom wiring harness # 3026-P is not a confirmed fit for your 2018 model as it was for your 2011 model. At this time we don't have a confirmed fit from any of our manufacturers. It appears that Buick has changed their connector and the only fit at this time is hardwiring the brake controller. For that, you can use the Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite Brake Controller 12" Long # 20127. I've attached a wiring

  • Finding Stoplight Circuit on 2018 Mazda CX-9 for Brake Controller Install
  • Hey Zach, so we haven't had the chance to install a brake controller in a 2018 Mazda CX-9 so we don't have the wire color for the stoplight circuit switch but we can still help. The easiest is to use a circuit tester like the part # PTW2993 to test all of the wires that lead to the brake pedal switch till you find the circuit that only has voltage when the brakes are applied. But when you connect to this you are simply attaching to the circuit and not cutting it and preventing it from going

  • Troubleshooting No Power to Brake Controller 12 Volt Power Wire On a 2013 Chevrolet Avalanche
  • There is one additional step that is required on your 2013 Chevrolet Avalanche that was not covered in the video with the 2012 Chevrolet Silverado. There is a red wire located just outside the engine compartment fuse box that needs to be attached to one of the front lugs inside the fuse box. You will need the M8 Nut # 185917 to complete this step. I have linked a video below for an installation we did on a similar Avalanche so you can see the additional step towards the end of the video.

  • Voyager Brake Controller Does Not Show Voltage with Manual Override Applied
  • The way a brake controller works is sort of like you described. In many proportion controllers, you actually have to be moving to get voltage when applying the brake but will see voltage when applying the manual override. The controller actually senses how much the vehicle is decelerating using an internal sensor. It does not monitor how hard you press the pedal but it does sense when you are pressing the brake. Of course usually how hard you press the brake does effect the rate of deceleration. If

  • Replacement Hardwire Brake Controller Adapter For Prodigy P3
  • You'll need to hardwire the Prodigy P3, which means the correct adapter is the Replacement Brake Control Harness # 20127. If you do not have a factory brake controller on your Ram you will not need to have it flashed; if you are replacing the factory brake controller there is a good chance you will (this is not a one size fits all answer which is why I can't give you a definitive yes).

  • What Pigtail Fits the Reese TowPower 8508211 on My 2007 Dodge Ram Pickup?
  • Yes! The pigtail that you need for your Reese TowPower 8508211 is the Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite Brake Controller 12" Long # 20127. This harness must be spliced into your wiring. We do not have a plug-and-play solution that works.

If you don't have these, the parts you need are the T-One 4-way # 119178KIT
