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, just plug the included harness into your vehicle. 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 you don't already have a 7-way plug at the back of your vehicle, take a look at our exclusive 7- and 4-way brake controller installation kit (ETBC7 - sold separately).


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.

Video Transcript for Trailer Brake Controller Installation - 2016 Ram 1500 39510

Today on our 2016 Ram 1500, we will be taking a look at and installing the Tekonsha Voyager trailer brake controller for 1 to 4 axles. This will be a proportional braking system for your vehicle, part number: 39510. We will also be using the Tekonsha plug-in wire adapter, part number: 3024-P. This is going to be a very simple, easy to use brake controller for your vehicle, giving you exactly what you need when you need it the most. Where your other brake controllers will have all your buttons that your going to press, different settings that you can do, this is going to be very easy with its turn-dial operation and your manual sweep here in the front, in case of emergency. It's going to be very simple and easy to use, with the gain knob being on the right to adjust the voltage going to our trailer brakes. If we turn it all the way to the right, it's going to be at full power; all the way to the left, minimal power. It will also have a little tab on the side that will point you towards that direction.

We'll go ahead and turn the power all the way up. On the other side, we're going to have our boost level, and we'll adjust our boost level based on the trailer that we're going to be pulling. Down here in the front we'll have our manual sweep to apply proportional braking to our trailer in the need of emergency. You'll see how it's green. When we apply the brakes it's going to turn red. Now let's go ahead and disconnect our trailer to watch that indicator light go off.

Plug in your trailer, and watch the light come on. This will let you know that the system is functioning properly. Now let's go ahead and see how it's installed. Now we'll go ahead and find our factory plug that we're going to plug in our adapter to. It'll be located just in front of the accelerator pedal up underneath the dash. We'll go ahead and pull it down so it's a little easier access and a little bit better to see.

We'll take our adapter and plug it in (plug clicks in), until it clicks in place. Then we'll go ahead and put this up underneath the back of our dash, zip-tied up however we're going to need it to hang, so it's a little bit better concealed. Once we have our Tekonsha adapter installed to our factory wiring harness, all we're simply going to do: line up the tabs, and plug in the back (plug clicks in). With it plugged in, it's now going to be operational. All we'll need to do is mount it up and we'll be ready to rock! Line up the holes on the side and mount the bracket. Now, this can be mounted just about anywhere where you want it.

Use the provided screws to thread it in and secure it. Once you have the screws started, we'll go ahead and secure that down. Go ahead and take your wire bundle, tuck it up back behind, and secure that using a zip tie. Make sure that it does not interfere with any of the vehicle operation, whether that's moving components such as your feet or the pedals, or the steering column. And that will do it for our review and installation of the Tekonsha Voyager brake controller, part number: 39510, on our 2016 Ram 1500.

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:

In case my first review posts, after an unsuccessful online chat with someone at etrailer, I called them and spoke with a very nice and knowledgeable man (unfortunately I didn’t catch his name). He walked me through the subtle differences between the 2nd generation Sprinter van 7-way factory plug and the 3rd (current) generation van which I have and via telephone I was able to get the Tekonsha adapter harness connected. Thanks etrailer!



by:

Works great, following instructions and installed the trailer controller. Not all defaclut to install and the hardest thing was getting a 66 Year old kid in position to install it under the dash! I don’t bend as easy as I use too.



by:

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:

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:

This harness fits more years than noted, so long as you have the green factory connector under the driver seat. I thought shipping this item would take several weeks but E-Trailer had it out in just a couple days. A quality product that worked perfectly and was easily installed.



by:

This made connecting my me REDARC Brake Controller easier than hard wiring.



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:

This brake controller was so simple to install with help from etrailer.
It unit operats the electric brakes on my trailer great and I love that I can adjust the braking power from inside my motorhome.



by:

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:

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:

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:

Hello Alex. I appreciate the follow-up on my brake controller and wiring for my Sprinter van. The wiring was plug and play. It was s little difficult running the wires, but I got it. Again the wiring was plug and play along with the brake controller. I plugged it in and it immediately worked. I haven't towed the trailer with it yet, but will soon. Thanks again for the information on what to buy. You made the project so much easier.



by:

It's always a great day when you can plug and play! No cutting or splicing wire with this kit. Works great!



by:

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:

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



by:

Plug it in and voila!



by:

Nice controller, compact and good instructions. I cut the plug and hard wired on my application (98 Sierra) Had no issues.



by:

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:

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:

Easy installation and seems to be a great product. I also used the harness for my 07 new body Silverado for a easy install. Videos are a great help as well . I will purchase all of my trailer and RV needs from ETrailer from now on.



by:

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



by:

Perfect set-up to add brake controller to my sprinter van



by:

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.



by:

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!!!!

    The green light on the Tekonsha Voyager Trailer Brake Controller # 39510 will only come on when a trailer with properly functioning brakes is connected. The light will turn red when either the brake pedal is pushed or the manual operation lever is used. I have included a link to the instructions below that includes troubleshooting in case you have an issue when you do connect to the trailer.

  • Parts Needed To Convert From Hydraulic to Electric Brakes on a Boat Trailer
    I recommend switching from hydraulic brakes to electric brakes as this will be far more cost effective and easier to install than an electric over hydraulic setup. In order to covert all you will need is a new set of electric braking assemblies, a 7-way trailer wiring harness, and a breakaway system. The electric braking assemblies will need to be choose accordingly based on your brake flange, axle capacity, and hub dimensions. The axle capacity is usually the easiest to find and will...

  • Will Voyager Brake Controller That Is Not Perfectly Horizontal Work On 2015 Ram 1500
    I called my contact at Tekonsha and asked about the installation of your Voyager brake controller, part # 39510 on your 2015 Ram 1500. They told me that the 6-degrees of pitch you have when the brake controller is installed may not be any issue but the only way to truly know is by testing it. Make sure you are in a safe area and test the braking action. If it is erratic and the brakes do not work well, you may want to step up to a brake controller like the P2, part # 90885. It has an...

  • Voyager Brake Controller LED Light Goes from Green to Red to Off with Brake Pedal Applied
    What you are describing sounds like an overload situation which can be caused by several factors or a combination of things. First, the easiest to check would be the trailer side and vehicle side connectors for any dirt and corrosion and clean them out. Corrosion can also build up behind the connectors where you cannot see it as easily. You will also want to make sure that the blue wire from the controller to the connector is intact with no nicks in the wire. If it had some exposed wire...

  • How To Locate Correct Hot Brake Wire On 1996 GMC 2500 For Installation Of Tekonsha Brake Controller
    On your 1996 GMC 2500 the brake stoplight switch is very hard to access in this model year, but the circuit can be accessed at a different point. Try looking at the electrical center down by your left foot. Look for a a position labeled NAT, which will include 2 male spade connectors. Try a circuit tester like part # PTW2993, on the spade on the right, and see if it goes hot when the brake pedal is pressed. Although this can vary by model, if the spade is hot with the pedal pressed, you...

  • Parts Needed to Install a Voyager Trailer Brake Controller on a 2011 GMC Sierra
    On a 2011 GMC Sierra, there is no port under the dash to plug in a wiring harness but there are tow package wires. You will find the wires under the dash and below the steering column held together with a white tag. The tag will list the functions of the wires. You will need to attach these wires to the 4 wires on the brake controller but they will not match color for color. The brake controller white wire is the ground, black is 12 volt power, blue is out to the trailer brakes, and red...

  • Mounting Location for a Tekonsha Voyager Brake Controller in a 2014 Jeep Grand Cherokee
    Looking at pictures of the interior of the 2014 Jeep Grand Cherokee it looks like the best place to install the # 39510 would be on the left side of the steering column either above or below the leg air bags. Most likely below would be the best option.

  • When Should Blue Wire on Tekonsha Voyager Show Power?
    When you test the Tekonsha Voyager # 39510 and get a constant 12 volts, that means your red wire is likely connected to the hot side of the brake switch and not the cold side of the brake switch. You need to use a circuit tester such as # PTW2993 to find the cold side of the brake switch, which is the one that will carry a signal only when the brake pedal is depressed. I've added a help article on brake controller installation which should be useful as well.

  • Can P3 Brake Controller be Installed in Place of a Voyager Controller on a 2002 Dodge Grand Caravan
    You will need to hardwire in the P3 brake controller # 90195 because there isn't a plug-in wiring harness for the 2002 Dodge Grand Caravan. But the wire functions and colors are the same on the P3 as they are on the Voyager so if your Voyager is an older model that doesn't have the plug on the back, like # 39510, you could easily splice white to white, black to black, blue to blue, and red to red.

  • Availability Of Plug In Pigtail For Tekonsha Voyager In A 2018 Ram 1500
    The Tekonsha Voyager # 39510 will indeed fit your 2018 Ram 1500 Laramie. There is a plug-and-play adapter made by Tekonsha for the 2018 Ram 1500, but it is currently unavailable with no ETA as of November 2023. The plug in adapter is part 3024-P. Since it is not available, we suggest instead the pigtail # 7894, which will require hardwiring.

  • No Light On Tekonsha Voyager Trailer Brake Controller Installed on a 2003 GMC Sierra
    If there is no trailer connected then there should be no lights lit up on the Tekonsha Voyager brake controller # 39510. Once a trailer is connected you should see a green light. On a 2003 GMC truck or SUV you should just have to plug in the controller using harness # 3015-P. There is a junction box on the left side of the floorboard on the drivers side. Remove the cover and plug in the controller on the top row, second sport from the left. I have linked a video that shows the location...

  • Install Harness Recommendation for Tekonsha Brake Controller in a 2008 Nissan Pathfinder
    If you use the install harness part # 3050-P when you install the Tekonsha brake controller # 39510 you wouldn't need to try and tap into the stoplight circuit at any point. It does this for you. Also, all versions of your 2008 Pathfinder are compatible with this connector so it will work. This adapter plugs into the 6-pin connector on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, taped to another harness...

  • Trailer Brakes Do Not Activate With Brake Pedal When Trailer is Sitting Still
    Actually that is a possibility. Proportional brake controllers will not engage the brakes with the pedal unless the tow vehicle is in motion. Another possibility is the red wire from the brake controller isn't connected correctly. It needs to be connected to the cold side of the stop light switch or the wire that is hot only when the brake pedal is pressed. I would also check any fuses related to towing and replace if necessary. If none of these ideas solves your problem let me know...

  • Troubleshooting Inactive Brakes/Brake Lights on a 2009 Chevy Silverado 3500
    From your question, it sounds like you are referring to the activation of your brakes themselves on your 2005 Chevy Silverado 3500. If you are referring to the brakes themselves, you simply need a 7-way wiring harness and a brake controller. Since it looks like your vehicle comes prepped with a 7-way already, that wiring preps your vehicle for the controller. I recommend the Tekonsha Voyager # 39510 or the Curt Echo # C51180. Both of these controllers are proportional controllers which...

  • When Should the TorkLift SuperHitch Original Trailer Hitch Receiver Be Used on a 1987 Ford F-250
    If you plan to be installing a truck bed camper and you want to tow a trailer then yes, the TorkLift SuperHitch Original Trailer Hitch Receiver part # TLF1000 will absolutely be your best option. The reason for this is because it allows you to use a TorkLift SuperTruss Hitch Extension like part # TLE1542 which will most likely be needed for clearance because of the truck bed camper. In order to add a 7-way to your F-250 you will want to use the 7-Way Pre-Wired Pigtail part # 20024. This...

  • Manual Control Does Not Work On Brake Controller Installed On 1999 Ford F-350
    I called my contact at Tekonsha about your Voyager Brake Controller, part # 39510. They told me they rarely see this problem but there is not a fix for it and the brake controller will need to be replaced. They said there is a malfunction inside the controller causing the problem. If you need to replace the controller I recommend the P2, part # 90885. This is our most popular because it is easy to install and operate. For a new plug-in adapter I recommend part # 3035-P.

  • Trailer Locks Up when Brakes are Applied
    Your controller has an adjustment to set the amount of power that is initially supplied to the brakes on the trailer. If you have tried adjusting the setting and still have the trailer brakes locking up, then you need to bench test the brake controller. Below I have posted a link to a video on how to test your controller. Using this guide will help to diagnose if the problem is the brake controller or eliminate it if the problem lies elsewhere.

The red wire must tap into the cold side of your vehicle brakes. You will need to use a circuit tester like # PTW2993 to find this wire. It will be the wire that carries a signal only when the brake pedal is pressed. The blue wire is for electric brake controller out put and will run to the trailer connector...

    The item that you selected, Tekonsha P3 Trailer Brake Controller, part # 90195, will work for electric over hydraulic unit, like the Hydrastar. I would recommend using the Tekonsha P3 Brake Controller as it has digital display and can troubleshoot problems. The Tekonsha Voyager Brake Controller, # 39510 and older model Tekonsha Voyager Brake Controllers are not designed to be used with electric over hydraulic brake systems. For installation of an aftermarket brake controller, you will...

    For the 2007 Ford F-150, you should have a port on the vehicle for a brake controller wiring adapter, # 3035-P, so hardwiring the controller should not be necessary. The harness will be located under the dash near the center console, and to the right of the steering wheel. I have included a link to the installation details below. If you attempted to hardwire the controller, the wiring probably is not going to have the same color/function as the 2002 model. That is par for the course with...
