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 Chevrolet Suburban'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 Chevrolet Suburban. 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 (sold separately) is available for most newer trucks and SUVs. One end of the custom adapter plugs into your Chevrolet Suburban, and the other end plugs into the controller - no hardwiring required.

Note: If a custom brake-control wiring adapter is not available for your Chevrolet Suburban, 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

See also's exclusive 7- and 4-way brake-control installation kit (ETBC7 - sold separately) if you don't already have a 7-way plug at the back of your Chevrolet Suburban.

Video Transcript for Tekonsha Voyager Brake Controller Manufacturer Review

Congratulations. And thank you for owning one of the most sophisticated trailer braking systems available today. Whether you tow for work or play, you can depend on Tekonsha to enhance your towing experience by working to make sure both your tow vehicle and the trailer it is pulling slow down and stop at the same time. Over the next several minutes we will show you some important set up steps to be sure you have the smoothest braking experience possible. If you have questions or need more specific information, please refer to the installation and owners guide enclosed with your controller. If this is your first installation, please listen for a moment for some important tips. Performance braking controls are directional.

This means that the back of the control must be positioned toward the front of the vehicle or in the direction of travel. Locate the mounting position on the face of the dash in the most convenient position possible and within easy reach. Many brake controls have a primary operating range, nose up or nose down. Refer to your installation instructions for the range that applies to your control. Most newer vehicles have a brake control vehicle plug in point located in the primary electrical harness under the dash. Use the vehicles specific wiring harness, sometimes provided by the automobile manufacturer or available separately from your brake control supplier, to connect the break control wiring. Then plug it in under the dash.

If your vehicle is older, or does not provide a plug in point, use the generic wiring instructions provided with the brake control or see your dealer for installation details. If you have questions, please refer to the owners guide. The first step in positioning the sensor for a Tekonsha Voyager brake control is to park the tow vehicle and trailer on as level a surface as possible. With the trailers connector connected to the tow vehicle, the first thing that you will notice is the bi-colored LED on the front of the control will be glowing green. This will let you know that you have a complete circuit between the tow vehicle and the trailer. Next, find the power control knob on the right side of the control and turn it clockwise toward the front of the vehicle until the maximum setting is reached. Next, press the brake pedal and hold it. Look at the bi-colored LED on the control. If the light is green in color, find the level knob on the left side of the control and rotate it counter clockwise toward the front of the vehicle until the LED begins to pulsate between green and orange. You will want to move back into the green by rotating the level knob on the left side of the control clockwise toward the rear of the vehicle just a little at a time. What you are doing here is setting the sensor at the transition point just between the green and the flashing red. Tow the trailer at about 25 miles per hour and do a couple of slow speed stops as if coming to a stop sign. And notice the feel of the trailer.

Does it seem to pull a little at the end of the stop? If it does, your sensor setting is a little too aggressive. Simply move the level wheel clockwise very slightly and repeat the stop. Repeat the procedure until you feel the truck and trailer brake smoothly together. If you feel a pushing sensation from the trailer it is because the opposite has occurred. And you have a delayed setting on the sensor control. Simply move the level knob counter clockwise slightly into a more aggressive position. Once this is done the control is set and should not have to be reset until such a time that the road conditions change or the trailer weight changes significantly. Keep in mind that the power knob should never be used to fine tune your control. Harsh, aggressive braking at slow speed stops is usually caused by an improper sensor setting. After you have driven several miles and the trailer brakes have warmed up, you may want to repeat this process to further refine your stops. Please refer to the owners guide on warming the brakes. Because every trailer is different, your brake control needs to learn the weight of the trailer and condition of the trailer brakes. This is required to determine the optimum power necessary during an emergency stop without trailer wheel lock up. First, rotate the knob on the right side of the control so it is in the 12 o'clock position. Tow the trailer on as level a surface as possible and attain a constant speed of between 20 and 25 miles per hour and engage the manual slide bar found in the front of the control.

You will notice that the bi-colored LED will turn from green to orange to red indicating an increase of current to the brakes. Hold this for a few seconds and release. If the trailer brakes did not lock up, increase the power by turning the knob on the right side of the control clockwise toward t he front of the vehicle and repeating the manual engagement. Repeat these steps until such a time that the trailer brakes are just below wheel lock up. If at anytime the brakes do lock during this procedure, reduce the power by turning the knob counter clockwise toward the rear of the vehicle. Now the setting has been made so that the power output is just below wheel lock up. It is that easy. For information to fine tune your system, for optimal performance, check your owners guide for details.

Appears to work so far but too early to tell for a long term assessment. Liked that my vehicle had a ready plug under the dash so no wiring hassles were experienced. 89499


Thanks Patrick and I like it just fine although have used it only once. Is actuated by the use of the brake pedal and can be utilized manually by moving the lever horizontally to the right. Much of the credit should be given to the gal that took my call with the order. Originally was going the cheap route with no proportioning on the TBC and she indicated that I would be very disappointed if more money wasnt tendered for a proportioning TBC. It always helps when your sales staff has technical knowledge on the products.

Seems perfect. I'll put 5000 miles on it over the next month. The three controls are easy to adjust without looking, though I'd prefer the side mounted knobs to stick out a little more, so you can grab them easier. 221933


They work great. I actually had the controller stolen out of the truck in Albuquerque this summer and replaced it with the same unit. \Unfortunately, I had to buy it quickly traveling so I paid more at a trailer supply store.At least the thieves didnt get the truck! A friend in the same parking lot wasnt as fortunate.

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

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

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

I chose the Tekonsha Voyager inertia activated brake controller because i wanted the inertia system rather than the time delay system but needed it at a reasonable price. I have not tried it yet but it checked out electrically. I have two minor issues: it did not come with a wiring adapter. Maybe none of them do but one is needed to make wiring easy. Fortunately, I ordered one at the same time. The other issue is that it requires the metal bracket for mounting but on my vehicle it sticks out too far and I bang my knee on it when I slide behind the wheel. I think I can use double backed tape for mounting and still have it positioned so the inertia part will work okay. 290689

In terms of this brake controller, it may have been an early failure as after hooking it up and following the setup procedure, the LED came on and then, during adjustment, got bright and then went out permanently. I will update this review when I debug the problem more fully. I know my wiring is correct but I may have a 12V feed issue that is causing this. One thing I will say is that overall is outstanding! I do all of my business with them and tell people about how great they are every chance I get. Every aspect of their operation is excellent from technical information and support to customer service. Great company! 132219

I loved this controller so much I put one in my other vehicle. For the price you can't beat it. Just don't forget you need the wiring harness item 7894 ($$) to go with it. Pros It is really easy to dial in how much brake you need. I dial it down when I get off the highway to prevent the trailer from pulling hard and increase it for higher speeds. Also you can pinch the lever the engage the trailer brakes without braking your vehicle to see just how much braking the trailer (only) is doing. Also there is an led indicator that turns from green to pink to red as more break is applied and serves as a good visual indicator. 333539

I installed this in a 2014 Nissan xterra, The xterra has a white plug in under the dash near the computer plug in. This brake controller was very easy to install when used with the plug in wire adapter. I tried the brakes, they worked fine. You do need to fine tune & ADJ the controller, but not a big deal. When the lights are green on the controller you have brakes. E-Trailer sells this as a kit with both items, I think at a fair price. The shipping was fast and it arrived 2 days faster than expected, Thanks George! If I ever need trailer related parts, that will be my first place to look. 248615

After a year, the Tekonsha Voyager is working great. It was easy to install in my 2002 Dodge Ram 1500, what took the most time was my deliberating on the best spot to mount it. The unit is very sensitive to your vehicles loading. So changes in stance under load or unloaded may cause you to have to adjust the unit for more efficient trailer braking, which I needed to effortlessly do the other day while towing. I just needed to remember that. A great product and etrailer is a great company. I was at etrailer online browsing my lastest parts list for my camper trailer just today. CA. 362421

Received product this weekend, installed, and tested it. Everything is working great! We have installed this same brake controller on several trucks and it works well. Website was super helpful because we could enter make and model of the truck and it told us which wiring harness to use. On top of that, we had a video to review on exactly how to install it on our truck. Finally, the company sent me an email to follow-up and make sure I had everything I needed. If only every website was so customer service oriented. AWESOME Purchase experience! 356070

Just as described. I had a four pin and that plugged into this wire harness and then I had two wires to run to front of car. Once under the hood there are a few other wires to run to battery and through fire wall into vehicle to connect to a break controller. My local shops wanted over $400 for parts and labor. I saved over $250 doing it myself. It took me about 3 hours. At least an hour was running wires through the fire wall. The engine compartment was very tight near firewall in my 2006 Toyota Sierra. 86763

I have installed and used several different types of brake controllers over the years, and this on is hands down the best I have used. Installation is typical, no real issues. I will say that unless you plan to remove your controller often, save the cost for the plug in pig tail and hard wire the unit (I wondered why I needed that part...) The beauty of this unit is the set up-easiest brake controller I have ever set up! Great price and works as advertised... unprecedented! 188411

I'd had one of these before so ordered for my current install, they're a good controller, however, it's limited to 20ยบ nose down on the install, so it didn't fit my current dash. My mistake, I should have checked before ordering. Decided to order a P3 to replace it, etrailer customer service was awesome, issued an RMA (I hadn't attempted to install it yet, just read the instructions and saw the limitation). I'd deal with this company 100 times out of 100 for my trailer needs! 24628

It is inexpensive for a proportional controller. Unfortunately, there is no way to test it with out having it attached to a trailer. It makes a clicking noise when you apply the brakes or use the manual over ride, so I guess I have it hooked up correctly. I won't be able to test it until I drive across the country to pick up new trailer. You Tube videos are great. I would not have tackled this very time consuming project if it were not for the detailed videos. 263746

by: Walter Calloway/ Donna Calloway07/15/2017

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


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.

Installed in 2006 Toyota Sequoia towing 5000 lb camper. Nothing fancy with this brake control unit, but I wanted simplicity. I have exact same unit in 2000 Silverado used for towing 5th wheel camper. 13 years of towing various trailers, never a problem braking, this unit gets it done!

I installed this controller on a 2013 Jeep Grand Cherokee. Installation was easy (as I had also purchased the adapter cable for my Jeep), adjustment instructions were clear and the controller worked perfectly. 79126

Comments also looking at installing on my 2013 Jeep Grand Cherokee. Am in Australia....not sure what the adjuster cable is and whether it is something I should mention to my Auto Electrician. Are you able to clarify?

-- comment by: Terry B - 08/07/2013


The adapter cable referenced is for plugging the brake controller into a port under the dash that Jeep provides on models with the factory towing package, in this case, it is part 3045-P. Please note this port will only be present and active on models equipped with a factory 7-Way trailer connector at the rear. These harnesses are also developed and designed for North American Market vehicles and if your Grand Cherokee was built for sale in Australia, it may not be compatible and could potentially damage the vehicle electrical system. In that case, it may be best to have the installer hard-wire in the brake controller and use an ETBC7 kit to complete the install. It would give the installer all the parts needed to add a 7-Way and wire the Voyager in.

I have not used this product for trailer brakes yet as I have not bought my travel trailer. Installing was very easy even without a factory stock plug to connect to. The only problem I had with the unit is there is no way to know if it works until you have a trailer plugged in (or you jump the connections at the plug). I had to hook up to a friends trailer just to know if it worked. Other than that, no complaints. 31165

Product installed easily. The calibration seems straight forward and I was able to do the preliminary setup. Due to weather and time, I have not done the road test 'fine tuning' but I imagine it will work great as well. This is a very good mid price range controller. I rarely buy the 'very best' nor do I buy the 'low end'. Mid range is usually a good product for the money and this seems to be just that. 118238

Awesome controller. We use them often our our equipment. Only problem we had this install, was locating the right wiring to tie into the brake circuit. New 2014 Chevy express van. Chevy only uses a 5 volt switched supply at the brake pedal. Ended up locating and tied into the brake light circuit for the 12 volts needed for controller to see the brakes are applied. 150511

Great brake controller. I installed it in a 2003 F350. I mounted it inside the compartment under the 4x4 shift knob. I had to remove the pins from the connector to feed them through a hole i drilled in the back of the dash. I did this so there were no exposed holes drilled in the dash face. Then i mounted the controller inside the compartment using velcro. 123947

This is the same controller I have in my '99 k1500. The installation video made this simple to install in my wife's '10 Yukon, which is factory wired, but GM did not provide the connector. The controller is simple to install, adjust and operate, it works like it should, and it cost less than the competators. What more could I expect? 382498

Easy to install and works fine. I was a little confused though. I watched this vied which was extremely helpful and told me exactly how to install the device however, the video says the wire butts are included, and they were not. Otherwise, all is good. 107567


That video is for a different brake controller, the Prodigy P2 part 90885. The installation will be similar, but not all the same parts are included. The P2 does include a loose wire pigtail and butt connectors. Plug-in connectors and the loose wire pigtail connector are sold separately for the Voyager controller.

I was nervous about wiring into an Outback with 100 miles on it, so I ordered by phone. I was given everything to make it an easy, safe job. That, along with the online videos, made it easy. At the dealer, i was quoted 450 for the hitch and another 450 to install a brake controller. Through you, I did both for less than 300. Thanks much. 369350

Meriah was fantastic in handling my order. She assisted me (as did other's on previous calls) in ensuring that I was ordering the right pieces. She made sure that my order was filled quickly as I was under a time constraint to get the hitch installed to go pick up a new camper. It has arrived and waiting on the install. Thanks! Steve 223573

I already had a Tekonsha Voyager Trailer Brake controller on my wife's vehicle. Why not keep it simple and put the exact same kind on mine. I don't haul trailers too often, so the simplicity of this one makes life easy. If you don't get enough help from the trailer, turn it up. If the trailer brakes too hard, turn it down. Perfect. 246128

Great brake controller. Easy install. Good costumer support. Installed in my motor home. 2017 Liesure Unity Murphy bed. Mercedes 3500 Sprinter. Mercedes dealer wanted over $800.00 to do install. I did it myself for the cost of Tekonsha voyager controller and pigtail wire harness. Plug and play as they say.. Thanks Good Support team. 374269

I'm in the car hauling business, and use two diesel Ford Excursions, pulling enclosed car hauler trailers. I have used the Tekonsha Voyager electric brake controllers with great success, and this is the 3rd unit I have purchased, and will install it in my son's 1999 F250 diesel that he will pull his new 5th wheel camp trailer with. 358526

very good service and product. I already had a tow package on my Nissan truck and the connect pigtail sent was a perfect fit. Took me about 1.5 hrs to install it and check it out. Very easy to adjust and the electric brakes are great. The unit and pig tail were less than $100 and that included shipping. Thanks 287349

Tekonsha Voyager Trailer brake controller was purchased to replace the one I installed in 2003, which finally failed after 14 years of service.

Follow up review: I just used this controller again this last week while pulling my camping trailer, and for the last year it has performed flawlessly. I know there are other brands that sell for up to double the money but I honestly can't see why you need to spend more in this case. I am a "happy camper"! 361034

I've used this controller on and off for the last year on my 2010 Rav4 pulling a 3000 lb enclosed trailer.

It took a bit of time to get it installed but it went smoothly and has worked great ever since. 360608

I pull a small camper with a VW Touareg. The electronics in the T'reg don't play well with top of the line brake controllers. I spoke with the Tekonsha rep and he recommended the Voyager. The Voyager is a very simple controller, easy to install, and works well. I don't miss the fancy display. ICS 271698


Still works great. Pretty much set and forget.

Installation was a breeze with the adaptor wiring for my truck. 20 minutes and the unit was installed. Once the truck was hooked up to our 24 foot trailer, setting the brake controller took another 10 minutes. A quick test drive to fine tune the brakes and we were good to go! 383479

Easy to install and hook up. I used the GM adapter so there was no wiring, just plugged it in. Videos on website and written instructions make the install pretty much fool proof. Will be hauling the trailer next week, so will have to save review of actual performance 192327
