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 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...

  • Troubleshooting Tekonsha Primus IQ TK90160 Showing Voltage Reading When No Trailer Is Connected
    I reached out to my contact at Tekonsha and based on the issue you are describing it sounds like the RV dealer either used the incorrect plug-and-play wiring adapter, or the functions of your factory trailer brake controller port are mixed up. The trailer brake controller should not have any voltage shown with no trailer connected as it only sends voltage when it detects resistance on the blue brake output wire. I recommend using a circuit tester # PTW2993 to test the wires going into...

  • Wiring Harness to Install a Tekonsha Brake Controller on a 2014 Ram 1500
    For a 2014 Ram 1500 you will need Tekonsha harness # 3023-P. Harness # 3021-P that you referenced fits 2010 to 2012 Rams. In 2013, Dodge created a multiplex electrical system they call the PowerNet. That continued into the 2014 model year. Because of the change, a new harness was needed, # 3023-P. It will still fit the same Tekonsha brake controllers too.

  • Recommended Brake Controller for 2014 Dodge Ram 1500
    We can absolutely help you out with a brake controller for your 2014 Dodge Ram 1500. The brake controller I strongly recommend is the Prodigy P3 # 90195; it is the most popular model we carry due to its effectiveness and ease of use. It will activate your trailer's brakes immediately in proportion to your Ram's brakes and offers three different boost levels so you can adjust your braking power. All you would need to install this is Custom Wiring Adapter # 3023-P. The P3 levels automatically,...

  • Troubleshooting P.L. Error Code from Prodigy P2 90885 in 2014 Ram
    The P.L. error code appearing on your Tekonsha Prodigy P2 # 90885 indicates that the power connection is being interrupted while your foot is on the brake pedal. This means that you will want to focus on both the controller BLACK power wire and WHITE ground wire connections. The issue could be as simple as a bent contact on the installation harness # 3023-P which is the part used to install the P2 in your truck. It is also possible that corrosion on either of those +12V and ground contacts...

  • Advantage of AirLift Air Springs That Include Internal Jounce Bumpers
    The advantage of the AirLift air spring systems that have an internal jounce bumper is that in the event of an air leak your Ram 1500 would not lose all of the extra suspension support. You would still have the internal jounce bumper as a fail-safe to absorb some bumps and shocks, although the adjustable leveling ability of air bags would be gone until you could repair the fault. Kit # AL88365 which fits both 2WD and 4WD versions of your Ram 1500 includes these jounce bumpers. The two...

  • Replacing Factory Brake Controller On Dodge Ram Truck
    I called my contact at Tekonsha and asked about replacing the Dodge Integrated Brake Controller if the truck is a 2010 through 2015. If you have a different year Ram just let me know and I can make some recommendations that will work for you. They told me the best way to go about replacing the controller is to take the vehicle to a Dodge dealership and have them disconnect the ITBM. Doing this will turn on a warning lamp on the instrument cluster. The dealership will then need to reconfigure...

  • Troubleshooting A 2011 RAM 2500 Giving a Service Trailer Brake System Error
    I did some research and it turns out that this error is fairly common amongst RAM owners. What this error is saying is that there is a problem with the ITBC (Integrated Trailer Brake Controller) system. My guess is since you're using an aftermarket brake controller and not the OEM brake controller the system might be a bit "confused" for lack of a better term, especially since the brake controller is working just fine. I'd recommend taking it to a local RAM dealer and see if they can...

  • Troubleshooting OEM Trailer Brake Controller in 2013 Ram 1500 Pickup
    If your Ram's OEM trailer brake controller actually sends out a brake signal when you press the pedal (meaning you can feel the trailer's brakes engage when you're driving) but it does NOT send out any signal when you press the manual override lever, then the unit is damaged internally and should be replaced with a high-quality aftermarket unit. You can test the controller's output right at the truck's 7-way socket if you have a circuit tester like # PTW2993, or a multi-meter like # PT89ZR....

  • Troubleshooting Factory Brake Controller of 2013 Dodge Ram Not Wanting to Work with EOH Brakes
    What is really frustrating about factory integrated brake controllers is that even the ones that say they are compatible with electric over hydraulic brakes don't always work properly. The factory controller of your 2013 Ram 3500 is supposed to be compatible with EOH brakes but we've found that in a lot of cases the only solution is to bypass the factory controller with an aftermarket one that consistently works with EOH actuators like the Prodigy P3 part # 90195. To install this in your...

  • Installing Aftermarket Brake Controller on 2013 Ram 3500 with Factory Brake Controller
    The adapter # HBA-CAM will not work with the HBA-12 unless the serial number is 705700 or greater. So you would need to install an aftermarket controller that is compatible with electric over hydraulic trailer brakes. I recommend using the P2 # 90885 with harness # 3023-P for a brake controller that is compatible with electric over hydraulic actuators. When you disconnect the factory controller to install the aftermarket one it will throw an error code on the dash. To get rid of that...

  • How to Install a Brake Controller on a 2014 Ram 1500
    Your 2014 Ram 1500 will have a connector under the driver's side dash that your brake controller will plug right into with an adapter. If you have the Tekonsha Prodigy P3 # 90195, for example, you will simply need to use the Custom Wiring Adapter # 3023-P for the connection. I have attached a video of the P3 and the adapter being installed on a 2016 Ram 1500 that you can use as a reference. If you do not have a Tekonsha brake controller and you are not sure what adapter you need, just...

  • Where are Connectors on 2014 Dodge Ram 1500 that Are Used to Install Brake Controller
    There are two harnesses under the dash of your 2014 Dodge Ram 1500 that are used for installing a brake controller. One carries ground, 12 volt power, and a circuit back to the 7-way of the truck and the smaller one carries just the stoplight circuit. Sounds like you are looking for the one that carries just the brake signal. For that you'll be looking for a small harness above the brake pedal. I attached a picture of where you'd find it but I the easiest way to see it will be to check...

  • Brake Controller Installed on 2015 Ram 2500 Only Showing 1 Volt of Output When Tested
    What's going on when you're testing the controller? Which controller do you have? If you have a proportional brake controller, you're only going to get a tiny bit of voltage on the output circuit with the brake pedal (which tells the controller whether a trailer is connected or not), because a proportional controller will only output voltage with the pedal when the vehicle is in motion. If you're testing using the manual brake switch on the controller, you should be getting voltage commensurate...

  • Tekonsha POD Power Trac Brake Controller Not Operating Trailer Brakes - Installed on 2014 Ram 1500
    Your brake controller isn't working with the brake pedal because your brake controller isn't sensitive enough to read the stop lamp switch voltage that's fed to it when the brake pedal is pressed. Beginning with the 2013 model year, Ram started using a multiplex wiring system for the stop lamp circuit. A multiplex circuit will use one wire for several circuits, with each separate signal being send as a different pulse. Because the stop lamp signal is only 9 volts at the most, and the #...

  • Trailer Brakes Only Work with Manual Override Using Reese Pod Electric Brake Controller in 2014 Ram
    It sounds like you have the red wired connected to the wrong circuit. You need to find the circuit from the cold side of your stop light switch that only has power when the brake pedal is pressed. Use a circuit tester, like # PTW2993, to check for power. If you'd rather just use the plug in adapter it's part # 3023-P.

  • Trailer Brake Controller on 2013 Ram 1500 Says Trailer is Not Connected when Trailer Is Connected
    The 2013 Ram 1500 was the first year for the new Powernet system used by Ram trucks. This new electrical system requires the use of a special brake controller harness, # 3023-P. Otherwise the brake controller will not receive the proper signal when you step on the brake pedal. However it should still work with the manual override. It may or may not recognize that the trailer is connected. It could be as simple as a loose connection or dirty/corroded connector or even a problem with the...
