  • Mounting: between -20 degrees and 70 degrees in the vertical plane
  • Warranty:
    • Limited 5-year on brake controller
    • Limited 1-year on wiring harness


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.

  • Most Economical Trailer Hitch Receiver and Wiring Harness For a 2023 Honda Pilot Touring
    Our etrailer Trailer Hitch Receiver # e27KR you found is our most economical custom fit receiver for your 2023 Honda Pilot Touring edition. For the wiring you can select from either the 4-Way # C48ZV or the 7-Way # C35ZV depending on the types of trailers you will be towing. If you have a trailer with a 7-way you are also most likely going to need a Trailer Brake Controller # 39510 along with the Wiring # 20127 to connect it. This is one of our most economical and reliable proportional...

  • 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...

    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...

  • 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...

  • 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...

    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 have...

    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 either...

  • Recommended Brake Controller for a 2018 Thor Ace Motorhome
    For your 2018 Thor Ace Motorhome, I recommend using the Curt Spectrum Trailer Brake Controller part # C51170. The reason for this is because this unit is composed of two main parts, the control box and the output knob. The control box gets mounted out of site and then the output knob will get installed up on your dash for easy use and a very aesthetically pleasing look. The color output of the knob also helps with ease of use. Since your motorhome is on a Ford F-53 chassis, you can use...

    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.

  • 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.

  • 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...

  • Trailer Break Control Installation for Tekonsha Prodigy P3 on 2019 Mercedes-Benz Sprinter 3500
    According to my research, if your 2019 Mercedes-Benz Sprinter 3500 came with a factory 7-way trailer connector you will have the brake controller connector pre-wired. This pre-wired connector should be under the driver side seat which you can see in the attached photo. The connector is green with four pins inside. Once you locate this connector you can install the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 using the Tekonsha Custom Wiring Adapter for Trailer Brake Controllers...

  • How To Install a Brake Controller on 2017 Mercedes-Benz Sprinter 3500
    You can hard-wire in a brake controller, and it seems that there are not a lot of the Sprinter 3500 models that are pre-wired, at least from what I've seen in my research. I have not seen any reports that this isn't possible, and we even have an installation video to walk you through the process. The way to find out whether or not the plug is present by using a circuit tester like the # PTW2993 and testing for a hot wire when the brake is pressed- it's possible that one of the plugs that...

  • Where is Brake Controller Install Connector on 2020 Mercedes Benz Sprinter 3500
    Your 2020 Mercedes Benz Sprinter 3500 with the factory tow package does have a brake controller install port like what the part # 3063-P is designed to plug in to. On your Sprinter you will find the harness underneath the driver seat. It will be a green connector you are looking for like what you see in the attached picture. Then for a brake controller the Brake EVN # TK63VR would be a really great option that is very reliable and performs great.

  • Are There Instructions To Route Tekonsha Brake Controller Harness On Mercedes Sprinter 2500
    The Tekonsha Custom Wiring Adapter for Trailer Brake Controllers part # 3063-P which is a fit for a Tekonsha Trailer Brake Controller like the Prodigy P3 part # 90195 on a 2018 Tiffin Wayfarer Motorhome with Mercedes-Benz Sprinter 2500 Chassis does indeed plug-in under the seat. In order to route the harness up to the dash where you would ideally be mounting the brake controller you'd need to find a path free from moving components.

  • Where is the Trailer Brake Controller Plug on a 2020 Mercedes-Benz Metris
    The trailer brake controller plug on a 2020 Mercedes-Benz Metris is located on the driver side behind the center console, under the sound deadening mat in the top left of the passenger footwell. I have attached a photo of this as well.

If you don't want to do all the work finding the connector...

  • Parts Needed to Install Brake Controller on 2019 Mercedes-Benz Sprinter 2500 With 7-Way
    Since your 2019 Mercedes-Benz Sprinter 2500 has the factory 7-way, that means you'll have the factory tow package, so I assume by "wiring" you are referring to the wiring adapter needed to plug into the brake controller (it will plug into the green port under your driver's seat as in the accompanying photo). The correct part for your '19 Sprinter 2500 is the Tekonsha Custom Wiring Adapter # 3063-P. Then for a brake controller that works with that adapter, there are a couple options I...

  • Parts Needed to Install Brake Controller in 2023 Sprinter
    I checked with Tekonsha and a few other brake controller manufacturers and they state that your 2024 Mercedes Sprinter 3500 does not have an OEM brake controller install port under the dash like previous models so you would have to hardwire in the Prodigy P2 # 90885 with the universal install harness it comes with and the brake controller install kit part # 5506 which wires to the OEM 7-way you have.
