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!

Exactly what I was looking for and needed ! It was delivered very quick . Actually I just ordered a complete wiring harness from you tonight . Your service and follow up is great

After 1 yr and many trips this product has more than exceeded my expectations. Would definitely recommend it to anyone



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: 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: 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.

The product has worked well. I have had no problems with it.



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.

Purchased this as part of all parts required to convert 1996 Jayco over to electric brakes. Very happy with results. Surprised to see after winter in storage that the battery supply still shows full charge.



by: Christopher07/09/2020

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.



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: Michael07/21/2022

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



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!

Plug it in and voila!



by: Don 03/07/2021

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.

These guys are great they had the installation kit it came with everything you need and even had a video for my specific vehicle to install the brake controller and wire in a 7 pin trailer plug
If you don’t have factory brake controller the etbc7 is an amazing kit they have comes with everything I mean everything

Everything has been excellent e trail has the right products and they fit just like they say



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: Buddy08/13/2023

We just installed this in our truck and install was fast and easy with adapter cable we ordered. and set up of controller was very simple.



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.

Thank you for your review. I have not heard of that problem. I would have used some electrical tape.

The correct items that fit properly were delivered in a timely manner.



by: Chad05/04/2023

I tried to purchase through my local business and was told that my vehicle was not wired for the brake control. They also refused to install since it was not factory wired for it. So I looked up etrailer and my vehicle info and sure enough my vehicle is factory wired and the picture you provided I was able verify the plug so I could order with confidence in a mater of 10 minutes. The unit showed up with correct wiring harness so my total install time was only 30 minutes. I can’t ask for anything more! Thank you!!!!

  • Are Trailer Brake Controllers Vehicle-Specific
  • Trailer brake controllers such as the Tekonsha Voyager # 39510 are not vehicle-specific but the parts required to install one can be specific to a year/make/model vehicle. For instance, many pickups have a port under the dash to allow quick plug-in installation of the Voyager. To find the correct harness you can enter your vehicle info into our Fit Guide. You can also always hardwire a controller using our all-inclusive kit # ETBC7. This has all the parts you need other than the controller

  • Trailer Brakes Work when Brake Controller Switch is Used but Not when Brake Pedal is Applied
  • With the proportional controller you will not get full power to the brakes on the trailer when sitting still.

  • What is the Orange Wire on a 2011 Chevy 1500 Used For When Installing a Trailer Brake?
  • No. According to the GM tech bulletin the orange wire you're seeing is for the Center High Mount Stop Lamp (CHMSL) on the rear cab of your truck. This wire is not used when installing a trailer brake controller like the Tekonsha Voyager Trailer Brake Controller # 39510. I've linked the instruction video for the Voyager on a similar Chevy Silverado for you to have a look at and help you with the installation process.

  • Green Light on Tekonsha Voyager # 39510 is Constantly On
  • If the Green light is constantly on when you trailer is disconnected then you have a short on the Blue wire somewhere or it has been wired incorrectly. The Blue wire on the Tekonsha Voyager # 39510 is the wire that carries the signal from your brake controller to the 7-Way on your 2012 Dodge Ram 1500 to activate your trailer brakes. If you are using the Adapter # 3021-P to connect it to your Ram then the wiring is most likely shorted somewhere. Check the pin in the 5 O'clock position

  • Tekonsha Voyager Trailer Brake Controller Not Working on 2017 Toyota Tacoma
  • If you are not seeing a green light on the Tekonsha Voyager Trailer Brake Controller # 39510 after you have connected the trailer to your 2017 Toyota Tacoma, I recommend first checking the trailer and vehicle connector for any corrosion or debris that may be preventing a secure connection with your vehicle.

  • Installing Tekonsha Brake Controller on 1992 Ford F-150
  • To install a Tekonsha brake controller, such as the PowerTrac Time Delayed Brake Controller # 39523, you would want a wiring harness. The Tekonsha and Draw-Tite Brake Controller harness # 20127 is designed to work with Tekonsha brake controllers. If you do not have a 4-way flat or a 7-way connector at the rear of your 1992 Ford F-150, you will want to install a wiring harness with a 4-way flat. I recommend the Tow Ready T-One Wiring Harness # 118316. This wiring harness will plug into

  • Does the Tow Package Wiring on a 2008 Chevy Colorado Match a Brake Controller Color for Color
  • On the 2008 Chevy Colorado with a factory tow package, the wiring for a brake controller is located under the dash, to the left of the brake pedal. The wire bundle should have a white tag on it that also lists the functions of each wire. You will need to match the wires to the brake controller by function, not by color. On the brake controller, white is ground, black is 12 volt power, blue goes out to the trailer connector, and red is in from the stop light circuit on the brake switch. It

  • 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

  • I'm not entirely sure what brake controller or wiring you have on your 2013 Toyota Tacoma, but I can tell you that to add a brake controller to your Tacoma you will need to first add Wiring Harness with 4-Pole Flat Trailer Connector # 118496 and then the Universal Installation Kit for Trailer Brake Controller # ETBC7.

  • 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

  • Installing Brake Controller on 2013 Dodge Grand Caravan with FactoryTow Package
  • It sounds like your Grand Caravan is wired like the Jeep Grand Cherokee. I have confirmed this by speaking with my contact at Tekonsha.

To complete the installation, you will connect the white wire of the controller pigtail # 20127 to the negative battery terminal, the black controller wire to the positive

  • How to Find the Brake Switch Wire to Install a Brake Controller in a 2013 Ford Edge
  • Traditionally (at least from 2004 to 2007) Ford has used a green wire on the brake switch to attach to the red wire on a brake controller. However, the only way to know for sure is to test the wires using a circuit tester like # PTW2993. Manufacturers can use any wire they want and if they run out of the normal color they use, they grab whatever is available to keep the assembly line moving. To test the wire, use the circuit tester to probe the wires. You need the one that only shows
