Proportional brake controller can be mounted within a 90-degree vertical range. LED monitor indicates braking action of trailer. Fine-tune power adjustment lets you set braking intensity to suit your towing needs.
Features:
Specs:
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.
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.
The Voyager is designed to be mounted in your cab at a vertical angle that is between -20 degrees and 70 degrees.


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 etrailer.com'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.

Tow Ready Replacement Plugin Harness for the Tekonsha P3, Voyager, Prodigy, and Primus Brake Controllers. Also works with Draw-Tite Intella-stop Xtreme, Intella-stop Ultra, Intella-stop Digital and Activator III (5520) brake controllers.
Video of Trailer Brake Controller Installation - 2001 Chevrolet Express Van
Videos are provided as a guide only. Refer to manufacturer
installation instructions and specs for complete information.
All right, today on this 2001 Chevrolet Express Van were going to install part #: 39523, this is the Tekonsha Power Track brake controller. Now to install this were also going to use part #: ETBC7, the brake controller install kit. Were going to start with that part first. Were going to start off of our wiring harness and start from the rear of the vehicle and work our way up. All right, next well go ahead and take our 7 pole bracket and were going to attach it directly to the bumper. All right, now well go ahead and take our seven to four pole adaptor, well attach it to the bracket, then well take the four pole and connect it to the preexisting four poles on the van.
Well use some dielectric grease to seal the connection up, connect the two four poles together and make a permanent connection out of it. All right, then well continue on with our gray wire and well run that to the front of the vehicle. Now, when we do well make sure stay away from anything moving like the suspension components or anything hot like the exhaust. Now well also take the white wire thats with the gray cable with the ring terminal and well attach that to the frame. Now to attach our ground were going to use a number 14 self-tapping screw.
Now, to run a wire up to the front were actually going to run all the way through the frame. Now, were using a piece of airline tubing to help run the wire through. This also can be a piece of stiff wire or something you can work with. Okay, well pull all the way up to the frame and then well run up through the engine compartment. Again, we want to make sure we stay away from anything moving or that gets hot like the exhaust.
Well run it up along the firewall and pull it out the top and then well use a zip tie to help secure the wire and take up the tension. Next well go ahead and install our circuit breakers. Were going to mount them to the inside of the fender well next to the battery. Now well take our duplex cable and well peel away the gray sheath. Our black wire will go on across the front of the vehicle to the 40 amp circuit breaker for a hot lead.
Then our wire well pull back and leave it out of the way for now. After we have our initial hook up to the circuit breaker well go ahead and take our white wire and then well pull it from the inside out. Now, on this vehicle theres a grommet thats missing in the firewall, so were going to use that hole to run our wires through. If there was a grommet there we would make a hole in the grommet and then run our wires through it. Now, since that weve ran out of cable on our install due to the way how we ran the wire from to rear and the lengths were going to add another piece of cable to it. Well use a ten foot length of wire, were using part #: 10-2-1. Well take this new length of wire and well run it from our 20 amp circuit breaker to the inside of the cabin to where were going to install our brake controller. Now, our black wire will be connected to the 20 amp circuit breaker and our white wire in this bundle will be attached to the factory ground. Okay, now that weve run our wires inside well go ahead and cut them to the length that we need. Then we can go ahead installing the wire harness for the brake controller. Now the wire harness were going to use is universal brake controller plug part #: 20127. Now, we hook up our wires, were going to start with our single white wire. Well connect that to the blue wire on our brake controller harness, then next well go to the gray cable with the black and white wires, well connect those color for color from the brake controller harness and our red wire well run up to the coal side of the brake switch. All right, at this point we can go ahead and start installing the brake controller. Well take our bracket and mount it to the bottom of the dash. Then well go ahead and take the brake controller and well get ready to install it to the bracket. Well go ahead and take one of the attachment screws and make some threads before we attach the brake controller to the bracket. Okay, well go ahead and attach it to the bracket. Well connect our wire plugs together and well zip tie the wires out of the way and well go back underneath the hood and make our final connection. Now, well run two wires to our power supply, one for the brake controller and one for the 40 amp circuit breaker for the 12 volt power supply out back. Normally you want to make your connections straight to the battery. However, due to the lack of room inside the engine compartment, with the battery, we cant really use battery extenders or post extenders. Okay, with our power hooked up well go ahead and attach the trailer to the vehicle and test the brake controller. Now, you can see we have a little green light on the LED. If we move the manual override over you can see how it turns to the green, to orange, to red and it also, since its a time delay brake controller, itll do the same thing when we hit the brake pedal. Okay, and with that, thatll finish it for our install of part #: 39523 from Tekonsha on our 2001 Chevrolet Express Van.

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. Etrailer.com was great, ordered from website, had the unit 3 days later, installed and towing on day 4...Thank you.68653

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'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

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
