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 splice the included pigtail harness into your vehicle and then plug the controller into it.


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 How to Install: Tekonsha Voyager Trailer Brake Controller on your 2022 Chevrolet Colorado

Hi there, Colorado owners. Then your 2022 Chevrolet Colorado we're gonna be taking a look at and showing you how to install Tekonsha's Voyager proportional Brake Controller. This is a proportional brake controller so the inertia sensor inside will detect vehicle movement. So if you ever slam on the brake show your body like kind of slams forward the inertia sensor detects that, and it knows that it's your vehicle is slowing down based on that. And it uses that along with your adjustment controls to give you the best breaking performance at the back. This is a very simple brake controller beyond the adjustment for a level and the output control.

On the other side, you just have your manual slide which can be used for if your trailer starts to sway or anything you kind of hit the manual slide to apply the brakes on your trailer and to help straighten you back out and get rid of that sway. And that's kind of it. This brake controller is just very simple gives you that fully proportional break output. And it does work with trailers up to four axles. We'll begin our installation here on the driver's side.

We're right down here at the kick panel. There's the parking brake pedal. I'm gonna go ahead and push it down just to help make things a little bit easier to see. And this panel here we're gonna be removing to remove the panel. You're just simply gonna pull up on it.

So your fingers should be able to grip underneath of it here. And kind of at this middle point here we're gonna pull up and we're gonna be working our way towards the back of the panel, pulling up on it. There we go. Once you get the back released and get towards the front here, you're gonna kind of pivot it like this and pull away from the wall here. You got a clip right there and that'll pop out of there.

And then we can just set this panel aside behind our panel. You're gonna find your factory break controller wiring and it's just taped right here cut the tape and that'll expose our wires there. We've got four wires here and this will hook into our brake controller. We're gonna use a harness. It has four wires on it as well. So everything will just match right up to what we've got right here. So we can make our connections. Now for demonstration purposes today we're not gonna be fully mounting it. We're gonna use some hook fasteners to secure it and we're not gonna be opening up the little hardware pack that it comes with. So that way we can repackage that. So we're gonna strip back each one of these wires and hook them up. I like to do it one at a time just because the red wire here, is your hot wire. So once you strip it back, that wire's live there. So I kinda like to get that hooked up right away to prevent it being stripped and potentially shorting up. So we're gonna go ahead and just take our start with our red wire here. It has a green Stripe on it. That's our main power wire. So we're just gonna strip it back. You may wanna trim a little bit off cause it's got those little ends on it there. So we'll probably trim a little bit of this off and then strip it, just to make it easier to strip with that material that it had on there. So give it a little twist makes it slide into the butt connectors more easily. We'll slide our butt connector on there and then we'll attach our wire to it. We can now hook this up to the appropriate wire here on our new harness. That's gonna be the black wire on our harness to power up our module, our brake controller. So we'll slide that in the other end of our butt connector and make our connection. So now that we've got that connected there we're just going to repeat that process to connect the rest of our wires. We'll be hooking the blue wire in our harness to the blue wire here on the vehicle. That's the output from the brake controller. So that'll send it down this wire to the back. The uh, white wire here on our harness is ground. And that'll actually hook to the black wire here on our vehicle. That'll be our ground. And then the red wire here, on our harness is for the brake signal input to the brake controller. So that's coming from your brake pedal here. So it lets the brake controller know when you're pressing the brake pedal and that'll connect to the white wire with the small blue Stripe on it there. So I'm gonna strip each one of these back and then make those connections and then you'll see those here. All right. So now that we've got all of our connections made here I'm gonna reinstall this panel and kind of tuck my wiring out the top of it when I reinstall it and we're gonna be mounting our brake controller roughly in this location here, that way it's kind of out of the way our wiring will reach it easily position it just off to the left so we can still access our hood release switch. And that is now fully reinstalled. We still have access to our wiring there to be able to Mount our controller. Now, typically when you mount your controller you're gonna screw the bracket straight into the dash. But again, for demonstration purposes we're gonna be using some hook and loop fasteners just to stick it there. So that way we don't mess up the dash here. That is not really how you wanna leave your brake controller installed 'cause this is an inertia based controller. So it means to detect vehicle movement. So it is important you screw it in place. Now, after we've got it mounted up we'll simply just plug our controller in that'll plug right into that harness. Now this harness doesn't, did not come included with the Voyager controller here but you can buy it kitted that way here at e trailer, to ensure that you get it with your brake controller. But if you just need the brake controller maybe you've already got one of these harnesses, you can buy just the brake controller by itself without the harness kited with it. After you plug in your brake controller you can kind of hide the wiring behind the dash there. And at that point you can see it's powered up. I plugged in the tester here to simulate a trailer. And if we hit our manual slide you should see the gauges activating on our tester there. And we can see we've got output. It's actually pulling ampage and it was operating both or it was operating our brake lights as well. You can see you get a real time display on top of the amount of output that you're putting towards your trailer's brakes based on the L E D light on top. Green being basically like no output going to yellow for a minimal amount, transitioning up to red for maximum. And as you slide the manual slide, you can kind of control how much of that output you're putting up. So once you verify it's working we do need to level this system. It's this very quick calibration. So that way the inertia sensor knows the angle that you've tilted it at to adjust that with your trailer connected and everything hooked up you wanna make sure the knob here on the right side is set to the maximum. So turn it fully clockwise to maximum put it to maximum output. And then the adjustment knob you see here on the left this is your level adjustment. We're gonna turn that one fully counterclockwise. So that's gonna be kind of turning it this direction. We're then gonna press the brake pedal. Our output is red. Red is gonna be the most aggressive setting. We wanna turn our level knob clockwise. Now bringing it back towards us. Once it turns orange, that's kind of your typical setting. That's usually where you're gonna wanna set that level adjustment at to get the typical output. But if for whatever reason you need a little bit more aggressive breaking you can tilt it. You can turn it a little more counterclockwise to get to that darker orange or red to be more aggressive. But you kind of wanna hover around that area of orange between that orange and like lighter red like right when you're getting into the red that'll get you at a nice setting for the inertia sensor to operate properly. And then we can use our maximum control knob here. This is the output from our brake controller. Just properly set that for your trailer. The heavier your trailer is, the higher you're likely gonna need this set. The smaller your trailer is and you can might be able to back it off and turn it down. You'll again, when you adjust that knob when you hit the brakes that will affect the L E D. So I've got, it turned fairly low and you can see it's a very light shade of orange but as I increase that, it becomes more aggressive. So just find the setting that works best for your truck and trailer combination there. And then you're good to go..

  • 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...

  • 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 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 have...

    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.

  • 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.

    For your 2006 Toyota Tundra, I recommend the Curt Trailer Hitch Receiver - Custom Fit - Class III - 2" # C13180. This is a square tube design with a black powder coat finish over a protective base coat for superior rust resistance. This is a no drill installation. For your wiring, I recommend the 4 Pole Harness and Hardwire Kit - Includes Tester # C59496. This will give you a 4 way flat connection. Then you will need to get the Universal Installation Kit for Trailer Brakes # ETBC7....

  • 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...

  • Installing a Trailer Brake Controller on a 2012 Dodge Caravan with Tow Package
    I spoke with a colleague who worked at Chrysler and he stated that they do not put the trailer hitch and 7-Way wiring on the Grand Caravan at the factory. That is something that the dealer installs. In any event here is what you will need to do. The brake controller will need to be hardwired into the vehicle. The white wire on the brake controller will need to get connected directly to the negative terminal on the vehicle battery. The black wire will need to connect to a 30 amp circuit...

  • Towing Setup for a 2017 Subaru Outback Wagon
    According to my research, your 2017 Subaru Outback Wagon has a max towing capacity of 1,000 lbs if the trailer does not have brakes or 2,700 lbs if the trailer does have brakes. You can improve the towing performance/efficiency of your vehicle with a transmission cooler like part # D13503 but you cannot increase it's capacity. The tongue weight rating of 200 lbs is correct but I cannot recommend you go over this. In order to set your Outback up for towing a trailer with brakes you will...

  • Troubleshooting Red Flashing Light on the Curt Venturer Trailer Brake Controller # C74VV
    If you check out the picture that I attached you can see that your Curt Venturer Trailer Brake Controller # C74VV that you installed is detecting an overload or short on the brake circuit of your 2008 GMC Sierra. The wiring adapter # C51515 that you also installed is the correct adapter so now we need to determine if the problem is on your Sierra or your trailer. If you have another trailer with brakes handy then you can simply hook up to that trailer and see if the same thing happens. Whether...

  • Recommended Fastway e2 Weight Distribution System for Coleman Trailer and Brake Controller
    The Fastway e2 # FA94-00-0800 has a weight capacity of 800 lbs as you mentioned, but weight distribution systems are rated for total tongue weight and have a range. The total tongue weight is the loaded trailer tongue weight plus any cargo weight behind the rear axle of your tow vehicle. If your loaded Coleman trailer is 540 lbs, then this system will work really well as your total tongue weight will be in the middle of its 400-800 lbs capacity. If you want slightly better ground clearance...

  • Curt Adapter # C57674 and Tekonsha Prodigy P2 and P3 Operation
    If you have the Adapter 4 Pole to 7 Pole and 4 Pole w/Test Lamps # C57674 correctly installed then the 12V light will remain on as that is 12V of constant current going to the adapter. The way that the Tekonsha Prodigy P2 # 90885 and P3 # 90195 brake controllers work is that they have to have a trailer connected and there has to be movement for the inertia sensor to actually send output to the brake controller pin on your 7-Way when the brake pedal is pressed. The way to test one of these...

  • Parts Needed to Install Prodigy P3 Brake Controller in 2018 Jeep Wrangler Unlimited
    Since the 2018 Jeep Wrangler does not come with factory brake controller wiring you'll have to hardwire in your P3 part # 90195. You will need to start with a 4-way (if you do not have one). For that you would want the # C55124. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this product...

  • Stop Light Switch Wire for Installing a Brake Controller on a 2013 Audi Q5
    According to my research the wire that carries the cold side of the stop light switch on your 2013 Audi Q5 should either be Red, Red/Gray, or Red/Black. You will need to test this with a circuit tester like part # PTW2992 and then connect the red wire from the pigtail # 20127 for the Voyager # 39510.

    I can understand not wanting to undo the wiring and then re-do it, and the pigtail harness is available separately for the Tekonsha Prodigy P3 # 90195. The correct part is the following: - Replacement Brake Control Plug-In Harness # 20127 One end of this will plug into the P3 and the other end will hardwire to your new vehicle.

  • Recommended Trailer Brake Controller and Wiring Needed for 2000 Toyota 4Runner
    For your 2000 Toyota 4Runner, I recommend the Tekonsha Voyager Trailer Brake Controller - 1 to 4 Axles - Proportional # 39510 with the Brake Control Plug-In Harness # 20127. This is the best controller under the price point you are seeking. Then for your wiring, if you already have a 7-way connector you can use the kit # 5506. If you have a 4-way then you will use the # ETBC7 kit which comes with the 7-way adapter and wiring. If you don't have a 4-way, then you will need that first and...

  • Where to Splice Brake Light Wire From Brake Controller To Stoplight Wire
    Since your vehicle does not have a brake controller port, you will want to use a universal wiring pigtail. For example, if you have a Tekonsha brake controller, you could use a Plug-In Harness for Tekonsha and Draw-Tite Brake Controllers # 20127. You will want to use a circuit tester, like # PTW2993, to test the wires at the stoplight switch at the back of your brake pedal to find the wire that only has signal when the brake pedal is depressed. Once you have found the wire that only produces...

  • What Hitch do You Recommend for My 2022 Subaru Forester?
    Definitely! The main factors that determine the hitch are hitch receiver opening size (either 1-1/4" or 2"), weight capacity offered, and how the hitch installs on your vehicle. For example, if you are looking for a hitch that is compatible with most accessories and provides you with the most weight capacity, I recommend going with a 2" hitch like the Curt Hitch - 2" # C13409. Not only does this hitch provide you with the most weight capacity we offer for your vehicle (525 maximum tongue...

  • What 4-Way and 7-Way Plug do You Recommend for My 2017 Subaru Outback?
    For the 4-pin harness for your 2017 Subaru Outback, I recommend using the Curt T Connector # C56040. The converter box in the Curt models is better quality than the Hopkins wiring options. There is no splicing required to install the T Connector onto your vehicle. Once the 4-pin is installed, you are ready to install the 7-pin harness. For that part, you need the Universal Installation Kit # ETBC7. This kit does require splicing into your current wiring. If you plan to use a brake controller...

  • Does Tekonsha Voyager Come With Wiring Harness for 2007 Silverado
    Hi Jeremy; the Tekonsha Voyager Trailer Brake Controller # TK29ER does include a wiring harness. However, it is the universal wiring harness so you will have to splice it in for installation. There are no custom wiring harnesses for the 2007 Silverado like yours. Our tech note says "No plug is present under the dash, but the needed wires are already run. You will connect the brake controller wiring with the vehicle wiring already present under the dash." I went ahead and attached an installation...

  • Brake Controller Options For A 2024 Jeep Grand Cherokee
    Hello Gordon. In the case of the 2024 Jeep Grand Cherokee, there is actually no difference between the brake controllers listed for vehicles with and without the factory tow packages. For example, the Tekonsha Prodigy P3 # 90195 is recommended for vehicles with or without the tow package. It comes with the 4-wire pigtail which is necessary for installation. Vehicles without the tow package will need to install the trailer wiring kits # C27BR and # ETBC7 in order to use a brake controller.

    Hello Jeffrey, thanks for reaching out. It is definitely possible to use the Tekonsha Voyager Brake Controller # TK29ER with your 2019 Volkswagen Tiguan, provided it is equipped with a 7-way trailer plug. Is your Tiguan already wired with a 7-way? If not, use the Tekonsha T-One # 118811, along with the # ETBC7 install kit. These two kits will contain everything you need to add a 7-way, including all the necessary wires for the brake controller. You could use really any brake controller...

Otherwise, a universal wiring option is necessary. Let's dig into yours.
