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

Proportional brake controller can be mounted within a 90-degree vertical range. LED monitor indicates braking action of trailer. Fine-tune power adjustment lets you set braking intensity to suit your towing needs.

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
    • Activates immediately - no pausing like with time-delayed brake controllers
  • Multiple mounting options
    • Position within 90 degrees in the vertical plane
  • Fine-tune adjustment for braking power and aggressiveness
  • Green LED monitors a secure connection with trailer
  • LED monitor changes color to alert you to braking action of trailer
  • Built-in, slide-bar manual override
  • Plug-in, vehicle-specific brake-control adapter can be used for certain applications to reduce installation time


Specs:

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


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 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

Installation of Tekonsha Brake Controller Adapter

Junction BoxBrake-Control Adapter Port

This adapter plugs into the port that is built into the electric junction box beneath your vehicle's dash. The black box is located to the left of the steering column, just above the carpet. To plug in the adapter, first remove the cover on the box. The adapter plugs into the second slot from the left, on the top row.


To install your electric brake controller you need to connect the wiring of the controller to your vehicle. Certain manufacturers offer pre-wired options, typically known as tow packages, wherein these wires are run for you from the dash to the trailer connector on the back of your vehicle. Often, a brake controller wiring harness is included with your tow package. This harness plugs into a port beneath your dash and connects to the four wires of the brake controller. If, however, you have a brake controller with a plug in place of the four loose wires, you can use the Tekonsha adapter.


This adapter requires no hardwiring. It is designed to plug directly into your electric brake controller for the simplest installation possible. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time and securely stow it away.

This was a fairly easy install and has a wide range of adjustment if your mounting level is not perfect. It has worked perfectly for a year and I am able to swivel it up and out of the way when I don't use it so it has no interference. Very happy with the adjustability of the unit and gives you piece of mind when we are towing a nearly 4000 lb trailer with a 4000lb SUV. 837232

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. 853184

I have had several of these over the years. I currently have 3 controllers on different trucks. I pull 5 different trailers with completely different weights. The controller works really well. I definately recommend this controller. You level it on the left side, which allows for placement in alot of areas of the truck. When I am towing I can adjust the brakes with the dial on the right side. Obviously the brakes need to be lighter when the trailer is empty. Simply turn the dial back until the brakes don't lock up. When I get it loaded I turn the dial forward until I can feel the brakes take hold. The lever on the front lets me manually apply the trailer brakes. I use this in cases where I am going downhill and it is better to let the trailer slow me down. If I ever need another controller, this will be it. Great price also. 92292

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. 272082

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. 8161

The break controller was what I ordered but the wire harness that was sent with it did not have a wiring diagram so I could wire it to my truck correctly. I had to go to a YouTube video to get the correct information so I could wire the harness to my truck without hurting the controller or the vehicle. Question: Does your company not send a diagram with all of your harness? Customer should not have to go to a YouTube video to install the product. 406364


Comments
Hi Walter and Donna, since brake controller wiring harnesses are not universal, manufacturers do not provide wiring diagrams in their packages because they do not know how or if your specific vehicle is prepped for a brake controller. However, we do have a help article on brake controller wiring, and general trailer wiring. I have included links for your reference. If you have any other issues do not hesitate to contact our tech experts.

Bought a new Primus IQ brake controller but it only came with a pigtail wiring that had to be spliced into my '01 Suburban. Ordered the direct fit wiring pigtail from etrailer.com and couldn't be more pleased! It literally took me less than 10 minutes to plug in the wiring and mount the brake controller. Excellent customer service and very fast shipping! The kind of shopping experience that causes repeat business. Thank you etrailer.com and customer rep Lexus for making everything so simple! 203301

1999 Chevrolet Suburban

etrailer's instructions and videos are awesome. installation was a breeze UNTIL I needed to locate the brake signal wire (cold side of brake switch) on my 1999 suburban. What a pain. the switch is not very accessible let alone there are a ton of white wires under the dash --along with an alarm. Long story short, I found this in a GMC forum and it saved me big time: "Under the dash, next to the emergency brake is a black convenience box. At the bottom of the box is the letters GRN, next to that is the letters NAT with a small recessed box with two male spade connectors. The spade on the right goes to the brake switch. The wire from the brake controller is terminated there." Using the supplied probe tester I was able to verify this and finished up my installation. The Tekonsha Prodigy P3 controller works great. 112192

  • The best place to mount a brake controller like the Tekonsha Voyager # 39510 is under the driver's side dash in a place so that it is within easy reach in the even that you need to activate the manual override. Technically it could be mounted to the floor but since that will be a little out of reach I recommend to the right of your dash under the steering wheel as you can see from the attached photo. This helps to keep it out of the way especially when getting in and out of your vehicle.

There should only be a minimal amount of volts at the trailer connector when the brakes are not activated If the problem still persists, you could cut the blue wire a few inches from the back of the controller. Then, using a circuit tester, check to see how many volts are coming from the back of the controller.

  • Where Is Brake Controller Install Harness for 2001 Chevy Silverado 3500
  • While it looks like you are pretty close to finding the correct port for installing a brake controller in your 2001 Chevy Silverado I attached a picture of where the install harness does plug in using a harness like the part # 3025-P. For a brake controller I would recommend the Prodigy P3 Brake Controller part # 90195. This is our best selling brake controller because of how well it works and how easy it is to setup.

  • Installing an Electric Trailer Brake Controller on a 2001 Chevy Silverado
  • On the 2001 Chevy Silverado, there should be a port, located in the electrical junction box on the driver side to the left of the brake pedal. Inside, you will need the port second from the left on the top row. You would use brake controller wiring harness # 3025-P. One end plugs into the Tekonsha Prodigy P2, # 90885, and the other end plugs into that port. There may also be some connections that will need to be made to make the brake controller and 7-Way trailer connector fully functional.

  • Brake Controller Installation on a 1999 Chevy C3500 Pickup Truck
  • On a 1999 Chevy C3500 there will NOT be a brake controller port to plug in a brake controller. The brake controller has to be hardwired into the truck. Chevy did not start putting in a port until they switched the trucks from C or K to Silverado. Prior to that Silverado was just a trim option. I have included a link to a video that will help. It shows installation on a 1996 C/K series truck. Installation will be basically identical on your 1999 model. If your truck already has a 7-Way

  • How to Determine if a 2002 Chevy Silverado 2500 HD has Factory Installed 7-Way Wiring
  • On your 2002 Chevy Silverado 2500 HD, you will need to look above the spare tire for a round plug with a cap on it. I have included a picture below that shows what the plug looks like. If your truck has this plug, then it has the wiring for a 7-Way. To add a 7-Way trailer connector at the rear of the truck, you can use Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End, # PK11893. The factory harness from under the spare tire will plug into the back of this connector.

  • Troubleshooting Open Ground Error Code for Brake Controller Install
  • The "open ground" error code of a brake controller indicates that the controller is losing the ground connection to the vehicle battery which is the white wire. I'd double check you have the # 3025-P seated totally in the junction box as well as make sure there's not damage to the connector or the pins of it. Also check for corrosion and fix as needed. As far as tracking down the ground circuit on the truck wiring that might be challenging. An easier solution would be to run a jumper wire

  • Installing a Brake Controller on a 2001 GMC Sierra 1500 with Factory 7-Way Trailer Connector
  • Since your 2001 GMC Sierra came with a factory installed 7-way trailer connector, GM should have already completed the connections under the hood at the fuse box. However, we have found that GM did not complete the wiring on all trucks, even if they came with the factory trailer wiring. If you plug in your brake controller using a plug-in style wiring harness, like part # 3025-P for Tekonsha brake controllers, and the brake controller does not power on, then the wiring under the hood

  • Brake Controller and Wiring Adapter for a 2002 Chevy Suburban
  • Although your friends Suburban might be equipped with the factory tow package, the package did not include a brake controller like it sometimes does in later models.

If he does not already have a controller, I would recommend the Tekonsha Prodigy P2, part # 90885. The wiring adapter, part # 3025-P will also be needed.

  • Troubleshooting Trailer Brake Wiring Issues on a 2002 Chevy Silverado
  • Thank you for being very detailed with your question! The first step I would take is to make sure everything on the truck and trailer is wired properly. Your Prodigy brake controller should have the wiring adapter # 3025-P which is custom for your 2002 Chevy Silverado. I recommend verifying you have the correct adapter because # 3015-P will also fit but it was pinned differently for the 2003-2006 Chevy Silverado's. The next thing I would check is the wiring for the 7-way connector

  • No Power on Red Brake Controller Wire when Brake Pedal Pressed on a 2013 Toyota Tundra
  • The wiring harness you should be using on your 2013 Toyota Tundra is # 3040-P. While it is unlikely it is wired incorrectly it is possible. You can use your test light to test the connector on the vehicle (where 3040-P plugs into) and see if it has power when you step on the brake pedal. If it does then check to see if the red wire is connected in the corresponding location in the harness. If not you can move it. If there is no power then there is something amiss on the vehicle side

  • No Trailer Brakes After Brake Controller Install on a 2000 GMC Sierra
