  • 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.

Do you have a question about this Trailer Brake Controller?


  • Should Blue Wire From Brake Controller Have Constant Power
  • The blue wire coming from the back of your Tekonsha Voyager Brake Controller # 39510 is for brake output to the 7-Way connector. This wire should only have power with the brake pedal depressed or the manual override activated on the brake controller. If you are getting constant power on this blue wire this may be an indication that the controller is bad but there is an easy way to test this. You will want to first sever the blue wire several inches from the back of the controller. Then

  • Troubleshooting No Green Light on Tekonsha Voyager Brake Controller
  • The green light on top of your Tekonsha Voyager Trailer Brake Controller # 39510 indicates that a trailer is connected to your vehicle. If this light is not turning on when connected to a trailer there are a couple things, you can check. I first recommend inspecting both the vehicle side and trailer side connectors for any debris or corrosion built-up around the pins that needs to be cleaned out. If the connectors look good, you will next want to test the brake output pin on the vehicle

  • Is Reese Voyager and Tekonsha Voyager the Same Brake Controller
  • They are the same controller as Reese and Tekonsha are made by the same company. The Tekonsha part # 39510 does not come with the vehicle specific install harness part # 3035-P which is custom fit for your 2003 Ford F-250/350.

  • What Are the Brake Controller Wire Colors for on a 1998 Dodge Ram 2500
  • The factory electric trailer brake controller wires on a 1998 Dodge Ram 2500 are as follows: Power - Red/Orange Ground - Black/Orange Stop Light - White/Tan Brake Output - Light Blue For a brake controller, I recommend using the Tekonsha Voyager Trailer Brake Controller part # 39510. It sounds like the previous owner of your truck may have cut off the old brake controller port so you are also going to want to use the Replacement Brake Control Plug-In Harness for Tekonsha and Draw-Tite

  • Troubleshooting Voyager Trailer Brake Controller Not Working when Brake Pedal is Pressed
  • It is possible that either the connection to the brake switch is no longer good enough to provide an adequate signal to the brake controller and a new connection will need to be made, or there is a short or possibly a bad ground causing the problem. You may want to also check the stoplight fuse. A blown fuse will not allow the signal to get through and the brake controller will not know you are stepping on the brakes. You can find the fuse by checking your owners manual which should

  • Where is the Brake Controller Plug In Located on a 2011 Ford F-250 Super Duty
  • On the 2011 Ford F-250 Super Duty, the brake controller port is located behind the center dashboard access panel on the passenger's side. One end of the # 3034-P adapter will plug into the back of the brake controller and the other end plugs into the brake controller port on your vehicle. If your vehicle has the factory 7-Way connector on the rear of your vehicle, then all of the wires for the brake controller have already been run. If you have a factory 4-Way connector on your vehicle

  • Troubleshooting Vehicle that Won't Start After Brake Controller Install
  • Without knowing what truck you have it's hard for me to know if you have the correct harness. I will say that the problems you are describing are unlike any problems we have ever seen from installing a brake controller. If removing the brake controller makes the problems go away then I would strongly recommend you do so until you figure out why this problem is occurring. Make sure you have your truck shifted into park or neutral before you attempt to start it. You may have moved the shifter

  • How to Find the Brake Wire on a 2001 Toyota Tacoma for Brake Controller Install
  • When we installed a brake controller in a very similar Toyota Tacoma as your (see attached install video), we found that the correct wire to use for the stoplight switch was dark green wire with a white stripe. You should still test this wire for voltage with the circuit tester to verify it is the correct one. But this would be an excellent starting point.

  • Moving a Tekonsha Voyager Electric Brake Controller From a 2004 Chevy Silverado to a 2009 GMC Sierra
  • Your 2004 Chevy included a connector under the dashboard to plug in an electric brake controller. Unfortunately, GM went away with this feature in all of their trucks for the 2007 to 2014 generation. So there isn't an easy plug and play harness available and you need to hardwire in the Tekonsha Voyager, part # 39510. Luckily, the wires to connect the controller to are all run to the cab of the truck. If you need wiring you can use part # 20127 for a harness to hardwire in. The wires

  • What To Do if an RV Dealership Installs a Brake Controller Incorrectly and Damages Cruise Control
  • It sounds like the RV dealership that installed your Tekonsha Voyager Brake Controller part # 39510 did not install the controller correctly initially, and even though he attempted to rewire the controller the damage was done to your vehicle and now you have lost cruise control. I would recommend having the mechanic look at the circuits like you are doing, and then once they confirm that the initial install of the controller screwed up your cruise control circuit I would go back to the

  • Casita Travel Trailer With Repeated Issues On Left Side Of Axle Only
  • Hello Paul. It sounds like you have an axle, or axle mounts that are out of alignment. That is really the only explanation since the issue has been reoccurring even after several replacements. I wonder if the 1st axle sustained damage of some sort which bent the mounts. This would explain the bearings overheating also. At this point I suggest you take your camper to a shop and have them check the alignment of the axles and the mounts.

  • How to Adjust the Tekonsha Voyager for 35 foot 5th Wheel Trailer
  • When you are setting up the braking power for the Tekonsha Voyager # 39510 you want to start off by setting the power (power knob is on the side of the controller) to the 12 o'clock position. With your trailer and truck fully loaded go ahead and drive on dry level pavement at 25 mph and then apply the manual override slide knob (found on the front). You can then adjust the power settings for this controller accordingly. I am attaching a review video for the Tekonsha Voyager as well

  • Troubleshooting A Tekonsha Voyager Brake Controller That Isn't Sensing The Trailer
  • Hi Howard, Typically if the Tekonsha Voyager Trailer Brake Controller # 39510 isn't detecting the trailer it's just an issue with the trailer connectors not making a solid connection. Check the pins on your trailer connector to see if they're corroded, damaged, bent, or dirty. A lot of the time the pins get bent back from connecting to the 7-way socket on the vehicle over and over and just need to be bent back into place with a thin flathead screwdriver so that they contact the pins in

  • No Power to Brake Controller on a 2005 Chevy Silverado
  • It sounds like you will need to make some connections under the hood to make everything fully functional and get power to the brake controller. Wiring harness # 3015-P is correct for your 2005 Chevy Silverado and it sounds like you have all the wires in the right place in it so it must be the connections under the hood. I have included a link to our help article that explains the connections under the hood, among other things, to get everything on the truck working. Specifically you

  • Tekonsha Voyager Brake Controller Not Activating Trailer Brakes When Brake Pedal Is Pressed
  • Yes, we can help you test your brake controller and determine if the controller is bad or if there is a wiring issue that is causing the problem on your 2003 Ford F-250 pickup. Lets start with the easiest things first. Be sure that when you are testing the trailer brakes with the brake pedal that the vehicle is moving. The trailer brakes will not apply with the brake pedal if the vehicle is not moving because of the proportional sensor. The first thing I would check is the red wire that

  • Brake Controller Turning On Brake Lights When Car is off and Draining Car Battery
  • It sounds like the unit was wired incorrectly. The white wire is a ground wire and should be connected to a suitable ground connection on the vehicle. The blue wire is the output wire that sends power to the trailer brakes when they need to be activated. The red wire should be connected to a stop light circuit. Typically, this is connected to one of the brake light switch wires at the top of your vehicle brake pedal. The black wire should be connected directly to the vehicle battery for

  • Troubleshooting LED Indicator Light on Tekonsha Voyager Brake Controller 39510
  • The green light on the Voyager brake controller # 39510 should come on as soon as you plug the trailer into the vehicle. If it does not come on at all, this indicates that you either have some corrosion inside the trailer or vehicle plugs that is causing a short, or you have a loose power or ground connection. Check the plugs on both sides of the setup for any white or green corrosion. If you see any, clean the plug thoroughly or just replace it. If you don't see any buildup in

  • Factory Port Location for a Brake Controller Wiring Harness on a 1999 Dodge Ram
  • I show that the Tekonsha Plug-In Brake Control Wiring Adapter, Dodge, item # 3020-P, and it works on all Dodge Ram Pickups from 1995 - 2009. You should be able to use the adapter that is connected to your Tekonsha Voyager brake controller, item # 39510, on your 1999 Dodge Ram. I believe you are looking at the wrong connector under the dash. You will need to look under the dash, near the emergency brake pedal for a white or blue connector that is above a white junction box.
