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 vehicle'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 vehicle. 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 is available for most newer trucks and SUVs. One end of the custom adapter plugs into your vehicle, and the other end plugs into the controller - no hardwiring required.

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

9030 Tekonsha Voyager Electric Brake Control

Tekonsha Custom Wiring Adapter for Trailer Brake Controllers - Dual Plug In
part number: 3023-P

Install your electric trailer brake controller quickly and easily with this custom wiring adapter. Simply plug one end of the adapter into your brake controller and then plug the other end into the built-in ports beneath your vehicle's dash.


  • Plug-in wiring adapter allows for quick, simple installation of your electric trailer brake controller
  • No cutting or splicing required
    • Custom connector end plugs into the built-in ports beneath the dash of your vehicle
    • Other end plugs into the back of your electric brake controller
  • Compatible with proportional brake controllers from Tekonsha
    • Brake controller must have built-in plug for adapter to connect - will not work on controllers with pigtail wiring harnesses
  • Limited 1-year warranty

Note: To illuminate your vehicle and trailer brake lights when you activate the manual override on your brake controller, use in conjunction with the Tekonsha brake controller converter with 7-way adapter (30235-P - sold separately). Required for use in the state of California.

Installation of Tekonsha Brake Controller Adapter

To install your electric brake controller, you need to connect the wiring of the controller to your vehicle. Certain auto manufacturers offer pre-wired options, typically known as tow packages, wherein wiring is run for you from the dash to the trailer connector on the back of your vehicle. When this is done, a port is installed at your dash so that you can easily plug in a brake controller.

This adapter plugs into the ports on your vehicle's built-in brake control wiring harness. The harness is located underneath the dash, to the left of the steering column, and it is taped to another harness near the emergency brake pedal.

No hardwiring is required to install this adapter. After you plug it into the factory port, you simply plug the other end of the adapter directly into your electric trailer brake controller. Because there are no wires to connect, installation is not permanent. You can unplug and remove your brake controller at any time to transfer it to another vehicle or securely stow it away.

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.

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

Installed easy and feels like its made well. I won't get a chance to use it for another week. The etrailer staff was very friendly and the shipping was fast. 116639


The brake controller has worked great over the last year. I have had no problems.

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

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

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 20º 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

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! Easy to install and set up. was great, ordered from website, had the unit 3 days later, installed and towing on day 4...Thank you. 68653

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

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.

  • Brake Controller Wiring Instructions for the Tekonsha Voyager # 39510
  • Depending on your vehicle year make and model, I will be able to provide instructions for wiring the Tekonsha Voyager brake controller. I have included the instructions for the Voyager, an FAQ article that features a basic diagram near the middle of the document, and an article on wiring a brake controller from scratch. The wires coming out of the Voyager attach as follows. The red wire attaches to the brake light switch wire that carriers a signal only when the brake pedal is pressed.

  • Tekonsha Voyager Brake Controller Not Activating Trailer Brakes When Brake Pedal Is Pressed
  • Yes, we can help you test your brake controller and determine if the controller is bad or if there is a wiring issue that is causing the problem on your 2003 Ford F-250 pickup. Lets start with the easiest things first. Be sure that when you are testing the trailer brakes with the brake pedal that the vehicle is moving. The trailer brakes will not apply with the brake pedal if the vehicle is not moving because of the proportional sensor. The first thing I would check is the red wire that

  • How Much Voltage Should Be Applied To Brakes on Trailer w/ Electric Brake Controller
  • Your brake controller should be getting 12 volts of power going into the brake controller. The wire that feeds power to the brake controller is the Black wire. You can test this wire by using a multimeter, part # part # BTMT15. The amount of power coming out of the brake controller depends on the adjustment of the gain on the controller. To test the voltage at the highest gain setting, you will want to sever the Blue wire a few inches from the back of the controller. Then, you will want

  • Tekonsha 9030 Voyager Brake Activator Wiring
  • You should have four wires coming out of the back of your Tekonsha #9030 Voyager Brake Activator, part # 39510. They should be white, blue, red and black. The white wire is grounded. The red wire must tap into the cold side of your vehicle brakes. The blue wire will run to the trailer connector on the back of your vehicle. The black wire must run to your battery to power the brake controller. If your trailer has 1-2 axles, use a 20 amp circuit breaker, part # PK54520, for this power

  • Troubleshooting LED Indicator Light Issues on a Tekonsha Voyager Brake Controller # 39510
  • It sounds like you are experiencing issues on the ground circuit of your Tekonsha Brake Controller, part # 39510. I would check to make sure that the white wire from the # 39510 is making good contact on the ground circuit. If you find corrosion or the wire not connected properly fix it as you deem necessary. If everything looks fine on the ground circuit I would next check the condition of the brake output (blue wire) looking for the same loose connections and corrosion. I attached

  • Installing 7-Way Connector on 2004 Ford Expedition with 4-Pole Trailer Connector
  • You are correct. That blue wire carries the output from the brake controller. To convert your 4-pole to a 7-way, use an adapter like part # 37185. The connector on the adapter would connect to your existing 4-pole. The remaining wires would connect as follows; the white wire would ground to the vehicle, the blue wire connects to the blue brake controller output wire and the black wire would be extended to attach to the positive battery terminal using an inline 40 amp circuit breaker like

  • What Do the Level and Gain Setting Do on a Tekonsha 9030 Voyager Brake Controller
  • On the Tekonsha Voyager brake controller, part # 39510, there are seven levels of brake intensity. You will need to decide how much brake you want applied to your trailer in relation to the amount of brake you are applying in your vehicle. For instance, let us say you are hauling a trailer that is heavier than your vehicle. If you are only lightly riding your brakes, you will need a little more power going to the brakes on your trailer to accomplish the same effect. In a case such as

  • Comparing the Tekonsha Voyager # 39510 and Tekonsha Envoy Electric Trailer Brake Controllers
  • The Envoy is an older brake controller that Tekonsha does not sell any longer. I do not know much about the Envoy controller so I asked my Tekonsha rep what he thought about the two and he stated that the Voyager is a more effective/reliable and user friendly brake control unit than the Envoy unit. The Tekonsha Voyager, part # 39510, is still sold by Tekonsha, and it has proved to be a valuable brake controller. I have added links to the Voyager instructions as well as a video review

  • Does the Light on the Tekonsha Voyager Brake Controller Only Come on When a Trailer Is Connected
  • You will need to have a trailer connected to the truck in order for the green light to come on on the Tekonsha Voyager Brake Controller, # 39510. You may see a light blink when you step on the brakes or use the manual override also and no trailer connected. To properly set up the controller, you will want to connect a trailer and then follow the set up steps in the instructions that I have linked for you.

  • Troubleshooting Tekonsha Voyager that Does not Apply Trailer Brakes Unless Manual Override is Used
  • There are a few things that can be checked fairly easily. The first is the inertia sensor. Inside the Voyager is a little pendulum that swings according to your braking, just like when you are pushed forward into your seat belt when you brake hard. This sensor reads how hard you are braking and sends the appropriate level of braking power to the trailer. The knob on the left hand side is the sensor level knob. It maye need to be adjusted if it got bumped. The power or gain knob on the

Since your brake controller shows no red light this indicates a short to the brake line (blue wire). If you are using wiring harness, # 3040-P, make sure that extra white ground wire is attached to a clean bare metal surface. If it is hardwired to the truck, the ground needs to be connected to the negative battery terminal. Sever the blue wire a few

  • Stop Light Feed Signal Circuit Options for a 2006 International 4300 Truck
  • If the brake pedal switch is not a 12 volt system on your 2006 International 4300 truck, another option would be to get the voltage from the the third brake light circuit. Sometimes this circuit is abbreviated as CHMSL. The reason you would not want to use the tail light brake light circuit is that if your brake light and turn signals were on the same circuit your brake controller would pulse with the blinker. I would recommend you use a circuit tester like the # 3808 to find the wire

  • Changing Idler Hubs on Small 5x8 Trailer to Electric Brakes
  • With a smaller trailer like you describe, electric brakes would be my recommendation both from a cost standpoint as well as the ease of installation. For the trailer, you would need two hub/drum assemblies and two brake assemblies. To determine if the hub/drum assemblies we offer are compatible with your trailer spindles, you will need to pull one of your idler hubs off, and look at the inner and outer bearing numbers. The hubs we offer, part # 84546UC3 use # L68149 inner bearings and

  • Trailer Connector Brake Output Pin on 2004 GMC Sierra Shows Constant 12-Volts
  • Are you by chance using a 7-way to 6-way adapter on the vehicle? There are two generally accepted methods of wiring the 6-way connector. One uses the center pin as the 12-volt accessory power feed, the other uses the center pin for the brake output voltage. If the adapter is wired one way and the trailer is wired the other way, the brakes are going to get 12-volts immediately upon plugging the trailer in. If you are not using the adapter, your trailer connector is most likely wired incorrectly.
