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 Tekonsha Voyager Trailer Brake Controller Installation - 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..

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:

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:

Day after I ordered this part I was contacted by the company to say that the part wouldn't be shipped for several weeks and they worked to get me a replacement solution. This ultimately did not work out but their customer care was something that has become a rare thing these days. I think the sales agent whose name I do not recall at the moment and a few days later got a notice that the original part I ordered was out for delivery. It arrived today I installed it in my vehicle and everything works perfectly. I would definitely do business with etrailer again for my RV needs. Thank you guys.

My Tekonsha P2 & wiring kit 3031-P for my 2017 Tundra Crew Cab arrived timely and installation was SUPER EASY. Connected my 27 foot trailer the same day to test it. Works awesome. Disappointed in Toyota for having a poor Brake Control System, but thankful Tekonsha was able to pick up the slack.



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:

Get this cable for a simple, plug-in installation. You’ll spend more time hunting for the junction already wired into the truck harness than installing your brake controller. And after installed, no worries on loosening wire connections or electrical tape wrap unraveling.



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:

I used this to connect a brake controller, ITEM TK63VR, to the brake harness under the dashboard of my husband's 2022 Toyota Tacoma SR5. It worked excellently and was very easy to do because the ends just snap right into the harness and the little ground wire fits right under the grounding screw. eTrailer's instruction videos are great, thats why this ol' grammy was able to do it herself! Thank you etrailer! PS I just wish that it was a foot longer.



by:

Wiring harness 3031-P on a 2015 Toyota Tundra, doesn't get any easier. I have cut and spliced several brake controller over the years. This is a lot cleaner and very easy.



by:

The wiring harness is exactly what most folks need for an under dash or dash mount. I found that it was more convenient to access the brake controller emergency handle and see the brake controller if I took your metal mounting bracket and turned it upside down and mounted the controller on the left hand side of the steering wheel on top of the dash with a magnet taped to the dash. This allow me to remove the controller and move it between my Tacoma and Ford F150 easily. But in order to do this you need a longer wiring adapter, so you either cut the original wiring harness and splice in longer wires or buy two harnesses and cut off one end of each and splice that together. Very happy with both the harnesses and the Tekonsha P3 brake controller.



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:

Installed my old Tekonsha P2 controller easily in the new truck in about an hour. Wire was just long enough to reach the preferred spot. Fantastic service as usual.



by:

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



by:

The cable fits the desired application on my 2018 Tacoma. A couple of inches longer would have been nice - it was barely long enough for where I mounted the controller. The location shown in the pic was the only location that didn't get in the way of of knees, feet or air bags. By the way, the other item in the cubby is my ham radio faceplate.



by:

Plug it in and voila!



by:

We love our Tekonsha brake controller. Works great on our 2018 Tacoma while pulling our 1025r John Deere subcompact tractor.



by:

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



by:

Delivered ahead of time and product is as expected.



by:

Everything came in the package and the product came earlier than I expected. Installing it was fairly easy. However the only thing that proved difficult was Torquing the ball down on the hitch head which luckily [RV dealer] was good enough to do that for me. I am happy With the product and looking forward to using it.



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.

  • Installation Of Brake Controller On 2016 Toyota Tacoma
    If you have a factory 7-way on your Tacoma, you can easily connect the brake controller by using a plug-in adapter like part # 3031-P. You simply plug one end into the back of the controller and the other end plugs into the brake controller port under the dash. If you do not have a factory trailer connector on your Tacoma you will first need to install a 4-way harness like part # C56349. You just plug this harness into the connection points behind the tail lights, and then run a hot lead...

    There are a lot of brake controllers out there but no worries; I will recommend some that are going to work the best for your towing needs and 2018 Toyota Tacoma. Since you have not used a brake controller before I recommend something that is easy to use and understand. For that the best option is the P3 # 90195.

  • Easy to Install Brake Controller Recommendation for 2019 Toyota 4Runner
    For your 2019 Toyota 4Runner with a factory 7-way I have a really easy brake controller solution that does not require you to find the brake controller install port under your vehicle dash. The easiest to install brake controller that also works really well is the Curt Echo Mobile part # C51180. Basically this just plugs into an active 7-way and once you sync it to your phone it's ready to go. This brake controller is proportional which means it senses the amount of deceleration your...

  • Tekonsha Brake Controller Installation in 2016 Toyota Tacoma
    The Tekonsha brake controller wiring adapter specified for your 2016 Toyota Tacoma with a factory-installed 7-way socket at the rear bumper is part # 3031-P. This harness connects a Tekonsha controller such as the P2 # 90885 to the factory port. On vehicles with the factory 7-way usually this port is located behind the left kick panel, above the e-brake pedal. It may be taped to other wiring and/or tucked up out of easy reach. Now if your truck does not have the factory 7-way you may not...

  • Green Light On the Tekonsha Voyager Brake Controller Lit with No Trailer Connected
    The green light on the Tekonsha Voyager Brake Controller, item # 39510, is designed to notify the user that the circuit for the trailer brakes is complete when the trailer is attached to the vehicle. If the light is on without a trailer connected there is a problem on the vehicle side. Usually the problem is corrosion in the trailer connector. This corrosion causes a false reading because the brake output terminal and the ground terminal in the 7-Way connector are both at the lowest point....

  • 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...

    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.

    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.

  • 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.

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...

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...

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...

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.
